1. This family is separated from the Formicariidae following Sibley & Ahlquist (1990), Sibley & Monroe (1990), Harshman (1994), Ridgely & Tudor (1994), AOU (1998), and Zimmer & Isler (2003). Sibley & Ahlquist (1985, 1990) found that the Thamnophilidae were the outgroup to all other furnaroid families, but this result has not been corroborated by other genetic data (Irestedt et al. 2002, Chesser 2004), which indicate that the Thamnophilidae is more closely related to the Conopophagidae than to the Formicariidae or any other furnaroid family.
1a. Genetic data (Irestedt et al. 2004) indicate that Hypoedaleus, Batara, Mackenziaena, and Taraba form a monophyletic group (Cymbilaimus not sampled).
2. Cymbilaimus sanctaemariae was formerly (e.g., Peters 1951, Meyer de Schauensee 1970) considered a subspecies of C. lineatus, but Pierpont and Fitzpatrick (1983) demonstrated that it is sympatric with lineatus and that the two differ in many ways, including voice.
2a. Zimmer & Isler (2003) suggested that Mackenziaena severa might be more closely related to species in the genus Frederickena than to M. leachii; Haffer (1987) proposed a close relationship between these three.
2b. Frederickena unduligera and F. viridis form a superspecies (Haffer 1987, Zimmer & Isler 2003).
2c. Parker et al. (1991) suggested that Frederickena unduligera may consist of more than one species.
2d. Frederickena unduligera was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937) placed in the genus Mackenziaena, but see Zimmer (1944). Genetic data (Irestedt et al. 2004) indicate that Frederickena and Mackenziaena are sister genera.
2e. Zimmer & Isler (2003) noted that vocal differences between the Middle American/trans-Andean transandeanus subspecies group and nominate major subspecies group of east of the Andes indicate that the former may merit recognition as a separate species from Taraba major.
2f. Genetic data (Irestedt et al. 2004) suggest that Sakesphorus (as represented by S. bernardi) may be embedded within Thamnophilus. Brumfield & Edwards (2007) found that bernardi indeed is the sister taxon to Thamnophilus atrinucha + T. bridgesi; they also found that melanothorax and melanonotus are members of a group of Thamnophilus that includes T. amazonicus, T. insignis, and T. divisorius. SACC proposal passed to move three species from Sakesphorus to Thamnophilus.
2g. Zimmer & Isler (2003) proposed that Sakesphorus canadensis, S. cristatus, and S. bernardi probably form a superspecies, but Brumfield & Edwards (2007) showed that bernardi is not part of that group.
2h. The northwestern subspecies pulchellus differs vocally from the others and may merit recognition as a separate species (Zimmer & Isler 2003).
3. Thamnophilus zarumae was formerly (e.g., Cory & Hellmayr 1924, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of T. doliatus, but Ridgely & Tudor (1994) and Parker et al. (1995) provided rationale based on differences in voice and plumage for treatment of zarumae as a separate species, and this was followed by Zimmer & Isler (2003) but not Dickinson (2003). Genetic data (Brumfield & Edwards 2007) indicate that they are not even sister taxa, with T. zarumae a member of the T. palliatus group of striped Thamnophilus.
3a. Zimmer & Isler (2003) noted that vocal differences among populations suggest that Thamnophilus doliatus may include more than one species.
3b. Zimmer (1933a) suspected that Thamnophilus multistriatus might be best treated as conspecific with a then-broadly defined T. palliatus. Genetic data (Brumfield & Edwards 2007) indicate that T. multistriatus is a member of the T. palliatus group of striped Thamnophilus, but that if tenuepunctatus is treated as a separate species from T. palliatus (see Note 4), then T. multistriatus should also be ranked at the species level.
3c. Brumfield and Edwards (2007) have published a phylogeny that will alter the linear sequence of species in the genus. SACC proposal passed to change linear sequence.
3d. Assis et al. (2007) claimed that they have "validated" (sic) that the subspecies capistratus of eastern Brazil is a species, but all that they showed was that capistratus is a diagnosable taxon (i.e., treated as subspecies under Biological Species Concept); whether capistratus merits species rank under the criteria used in this classification seems unlikely in that Assis et al. (2007) found no significant difference in any lousong characters between capistratus and doliatus from adjacent Brazilian Amazon.
4. Thamnophilus tenuepunctatus (with subspecies tenuifasciatus and berlepschi) was formerly (e.g., Peters 1951, Meyer de Schauensee 1970) considered a subspecies of T. palliatus, but see Cory & Hellmayr (1924), Ridgely & Tudor (1994), and Zimmer & Isler (2003); they constitute a superspecies; genetic data (Brumfield & Edwards 2007) confirm that they are sister taxa.
4a. See Cory & Hellmayr (1924) and Ridgely & Tudor (1994) for use of "Lined Antshrike" for tenuepunctatus and "Chestnut-backed Antshrike" for T. palliatus.
4b. Thamnophilus nigriceps and T. praecox are sister species (Zimmer 1937a) and form a superspecies (Ridgely & Tudor 1994, Zimmer & Isler 2003); genetic data (Brumfield & Edwards 2007) confirm that they are sister taxa.
5. Pinto (1937), Peters (1951), and Meyer de Schauensee (1966) considered cryptoleucus to be a subspecies of Thamnophilus nigrocinereus, but see Ridgely & Tudor (1994) and Zimmer & Isler (2003) for continued recognition of this species as separate from T. nigrocinereus, following Meyer de Schauensee (1970); they constitute a superspecies (Haffer 1987, Sibley & Monroe 1990); genetic data (Brumfield & Edwards 2007) confirm that they are sister taxa. Cory & Hellmayr (1924) treated cryptoleucus as a separate species, but in the genus Myrmeciza.
5a. Zimmer & Isler (2003) noted that vocal differences among subspecies indicate that Thamnophilus nigrocinereus may include more than one species.
5b. Thamnophilus aethiops and T. unicolor form a superspecies (Zimmer & Isler 2003). Genetic data (Brumfield & Edwards 2007) confirm that they form a group that also includes T. aroyae.
5c. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that Thamnophilus aethiops may consist of more than one species.
6. Thamnophilus schistaceus and T. murinus are presumably sister species (Zimmer & Isler 2003), as suggested by their traditional placement together in linear sequences. Genetic data (Brumfield & Edwards 2007) confirm that they are sister taxa.
6a. Formerly (e.g., Meyer de Schauensee 1970) called "Black-capped Antshrike," but see Ridgely & Tudor (1994); followed by Dickinson (2003) and Zimmer & Isler (2003).
7. Thamnophilus atrinucha, T. stictocephalus, T. sticturus, T. pelzelni, and T. ambiguus were formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Meyer de Schauensee 1970) considered conspecific with T. punctatus, with the broad species known as "Slaty Antshrike," but see Willis (1982) and Isler et al. (1997) for recognition as species, based mainly on vocal differences. Genetic data (Brumfield & Edwards 2007) indicate that atrinucha and punctatus belong to separate groups within Thamnophilus. Ridgely & Greenfield further recognized leucogaster of the Marañon Valley as a separate species; this taxon was tentatively retained as a subspecies of T. punctatus by Isler et al. (1997), with further evidence confirming subspecies status presented by Isler et al. (2001). Genetic data (Lacerda et al. 2007) indicate that ranking pelzelni and ambiguus as species is consistent with levels of divergence within this group.
7a. The subspecies cinereiceps may was formerly (e.g., Cory & Hellmayr 1924) treated as a separate species from Thamnophilus amazonicus, but see Zimmer (1933b), Pinto (1978), and Ridgely & Tudor (1994).
7aa. Newly described: Whitney et al. (2004). SACC proposal passed to recognize divisorius as a valid new species.
7aaa. Thamnophilus divisorius and T. insignis are sister species (Whitney et al. 2004, Brumfield & Edwards 2007).
7b. Thamnophilus amazonicus and the T. punctatus complex have been considered closely related, and there has been some taxonomic confusion between the two in the past (see Zimmer 1933b). Brumfield & Edwards (2007), however, found that they belong to different groups within Thamnophilus, with T. amazonicus related to a group that includes "Sakesphorus" melanothorax, T. insignis, and T. divisorius, and the South American T. punctatus group the sister to T. nigrocinereus + T. cryptoleucus.
7b. Meyer de Schauensee (1966) and Ridgely & Tudor (1994) suggested that Thamnophilus caerulescens may consist of more than one species; Cory & Hellmayr (1924) considered the western subspecies connectens, aspersiventer, and melanochrous each as separate species, but these were all considered conspecific with T. caerulescens by Zimmer (1933b) and Peters (1951); other authors (e.g. REF) have also considered the subspecies gilvigaster as a separate species. Vocal and genetic data support continued treatment of the Bolivian taxa, where most of the plumage extremes are represented, as subspecies of a single species (Brumfield 2005, Isler et al. 2005).
7c. Short (1975) suggested that the Andean subspecies (marcapatae and jaczewskii) might warrant recognition as a separate species from Thamnophilus ruficapillus, but see Ridgely & Tudor (1994).
7d. Sibley & Monroe (1990) considered Thamnophilus amazonicus and T. caerulescens to form a superspecies, but see Zimmer & Isler (2003) and Brumfield & Edwards (2007).
7f. Plumage and vocal characters strongly suggest that Thamnophilus ruficapillus and T. torquatus should be placed next to the T. doliatus group in linear sequences (Ridgely and Tudor 1994), and this change in sequence was made by Zimmer & Isler (2003), who considered them to form a superspecies. Genetic data (Brumfield & Edwards 2007) strongly support this, with T. ruficapillus and T. torquatus are sister species and closely related to T. doliatus. SACC proposal passed to change linear sequence of species.
8. Called "Guianan Slaty-Antshrike" in Isler et al. (1997), but see Isler et al. (2001).
8a. Correct spelling is "alixii" (Sibley & Monroe 1990), not "alixi", as in Meyer de Schauensee (1970).
9. Recently described: Lanyon et al. (1990).
10. Genetic data (Irestedt et al. 2004) indicate that Thamnistes and Pygiptila are sister genera. Proposal needed to change linear sequence.
10a. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that Thamnistes anabatinus may consist of more than one species.
10b. <note needed>
10c. Dysithamnus puncticeps presumably forms a superspecies with Middle American D. striaticeps (AOU 1983, 1998).
11. Dysithamnus occidentalis was formerly (e.g., Peters 1951, Meyer de Schauensee 1970, Hilty & Brown 1986) placed in Thamnomanes, and previously considered a subspecies of Thamnophilus aethiops (Cory & Hellmayr 1924), but see Zimmer (1933a), Willis (1984a), Whitney (1992), and Ridgely & Tudor (1994). The subspecies punctitectus was described as a separate species and in the genus Dysithamnus (Chapman 1924) while occidentalis was still considered a subspecies of Thamnophilus aethiops; Zimmer (1933a) provided rationale for considering this form a subspecies of D. occidentalis. See Ridgely & Tudor (1984) for the complex taxonomic history of this species. Donegan et al. (2007) noted that the Andean Dysithmanus (leucosticus and occidentalis) have similar bill structure, bill length, wing length, mass, male and female plumage, elevational range, distribution and habitat use to Thamnophilus unicolor; whether this refledcts relationships or convergent evolution is not known.
11a. Formerly called "Western Antvireo" or "Western Antshrike" (e.g., Meyer de Schauensee 1970), but see Whitney (1992).
12. Dysithamnus plumbeus was formerly (e.g., Cory & Hellmayr 1924, Peters 1951, Meyer de Schauensee 1970) placed in Thamnomanes, but see Schulenberg (1983) for a return to the classifications of Pinto (1937) and Phelps & Phelps (1950a).
12a. Meyer de Schauensee (1966) and Ridgely & Tudor (1994) proposed that the Andean and Venezuelan subspecies, leucostictus and tucuyenesis, might be best treated as a separate species from Dysithamnus plumbeus. Sibley & Monroe (1990), Ridgely & Greenfield (2001), and Zimmer & Isler (2003) treated leucostictus (with tucuyensis) as a separate species from D. plumbeus. Hilty (2003) further treated tucuyensis as a separate species from leucostictus. SACC proposal to elevate these to species rank did not pass. Isler et al. (2008) provided vocal evidence that leucostictus (with tucuyensis) should be treated as a separate species from D. plumbeus. Proposal badly needed. <Zimmer working on one>
13. Thamnomanes ardesiacus and T. saturninus have been treated as conspecific by many (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Hilty & Brown 1986, Sibley & Monroe 1990); see Ridgely & Tudor (1994) for rationale for continued recognition as separate species; they form a superspecies (Ridgely & Tudor 1994, Zimmer & Isler 2003).
13a. Thamnomanes ardesiacus and T. saturninus were formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Phelps & Phelps 1950a, Peters 1951) placed in Dysithamnus, but see Meyer de Schauensee (1966) and Zimmer & Isler (2003).
14. Thamnomanes caesius and T. schistogynus form a superspecies (Haffer 1987, Sibley & Monroe 1990, Ridgely & Tudor 1994, Zimmer & Isler 2003); they were formerly (e.g., Cory & Hellmayr 1924, Zimmer 1932b, Pinto 1937, Peters 1951) treated as conspecific, but there is no sign of intergradation where their ranges approach.
14a. Gyldenstolpe (1951) and Pinto (1978) treated glaucus (with persimilis) of southeastern Brazil as a separate species from Thamnomanes caesius.
15. Similarities in foraging behavior and some vocalizations suggest that Xenornis is most closely related to Thamnomanes (Whitney & Rosenberg 1993). <and Megastictus?>
15a. Called "Gray-faced Antbird" in (REF Eisenmann?), "Speckle-breasted Antshrike" in Meyer de Schauensee (1970), and "Speckled Antshrike" in Ridgely & Tudor (1994) and Zimmer & Isler (2003); see Remsen (1997) for retaining "Spiny-faced Antshrike," as in Wetmore (1972), AOU (1983, 1998). SACC proposal to change to "Speckle-breasted Antshrike" did not pass.
16. Hackett & Rosenberg (1990) found that Pygiptila is closely related to some Myrmotherula (the fulviventris group; see next Note) and that retention of this monotypic genus may make Myrmotherula paraphyletic.
16a. Genetic (Hackett & Rosenberg 1990) and vocal (Zimmer & Isler 2003) data indicate that the "stipple-throated" species of Myrmotherula (M. fulviventris through M. erythrura) form a monophyletic group that may be more closely related to Pygiptila than to other Myrmotherula. Irestedt et al. (2004) found that Myrmotherula was polyphyletic but found no relationship to Pygiptila, which they found to be closely related to Thamnistes and Myrmornis. Isler et al. (2006) named a new genus, Epinecrophylla, for the stipple-throated antwrens. SACC proposal passed to recognize Epinecrophylla.
16aa. Called "Fulvous Antwren" in Wetmore (1972).
16b. Zimmer (1932) suggested but although that the subspecies phaeonota might merit recognition as a separate species from Epinecrophylla leucophthalma, they are best treated as conspecific; see that paper for reallocation of subspecies to E. leucophthalma and E. haematonota from previous classifications.
16c. Epinecrophylla haematonota, E. fjeldsaai, and E. spodionota form a superspecies (Zimmer & Isler 2003). Epinecrophylla spodionota (with subspecies sororia) was formerly (e.g., Zimmer 1932, Peters 1951, Meyer de Schauensee 1970) considered conspecific with E. haematonota, but see Hilty & Brown (1986), Parker & Remsen (1987), and Ridgely & Tudor (1994). Epinecrophylla haematonota, E. fjeldsaai, and E. spodionota (Sibley & Monroe 1990, Zimmer & Isler 2003). Epinecrophylla haematonota and E. spodionota were considered subspecies of E. leucophthalma by Cory & Hellmayr (1924).
16d. Zimmer (1932a) suggested that Epinecrophylla erythrura and E. gutturalis were sister species; Haffer (1987) considered them to form a superspecies, along with E. gularis.
17. Recently described: Krabbe et al. (1999).
17a. Called "Yasuní Antwren" in Ridgely & Greenfield (2001).
18. Ridgely & Tudor (1994) suggested that Epinecrophylla ornata might consist of more than one species; the subspecies atrogularis was considered a separate species from Epinecrophylla ornata by Cory & Hellmayr (1924), but Zimmer (1932a) provided rationale for their treatment as conspecific.
19. Genetic (Hackett & Rosenberg 1990) and vocal (Zimmer & Isler 2003) data indicate that the yellow-bellied species of Myrmotherula (M. brachyura through M. longicauda) form a monophyletic group.
20. Peters (1951), Meyer de Schauensee (1970), Ridgely & Tudor (1994), and most recent references treated the taxon ignota as a subspecies of Myrmotherula brachyura. Ridgely & Greenfield (2001) treated ignota as a separate species ("Griscom's Antwren"). Isler & Isler (2003), however, demonstrated that ignota should be treated as a separate species from M. brachyura, and also provided rationale for merging M. obscura with M. ignota (which has priority), as proposed by Meyer de Schauensee (1966). Isler & Isler (2003) proposed the name "Moustached Antwren" for the combined species, and this was used by Zimmer & Isler (2003). SACC proposal passed to follow Isler & Isler (2003). Thus, Myrmotherula obscura ("Short-billed Antwren") is considered conspecific with, and a subspecies of, M. ignota.
20a. Myrmotherula sclateri and M. ambigua form a superspecies (Zimmer & Isler 2003); Zimmer (1932), who described M. ambigua, considered it likely that they were conspecific.
21. Myrmotherula multostriata was formerly (e.g., <check Hellmayr>, Pinto 1937, Phelps & Phelps 1950a, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of M. surinamensis (broadly known as "Streaked Antwren"), but see Isler et al. (1999) and Hilty (2003) for treatment as a separate species (and for linear sequence); this was followed by Zimmer & Isler (2003).
22. Called "Pacific Streaked-Antwren" in Ridgely & Tudor (1994) but see Isler et al. (1999) and Zimmer and Isler (2003), who noted that its sister species might be M. cherriei.
22a. Zimmer and Isler (2003) noted that vocal similarities suggest that Myrmotherula klagesi and M. longicauda are sister species.
22b. Gyldenstolpe (1930) recognized the southern, foothill subspecies australis as a separate species, but this has not been followed by subsequent authors; see Zimmer (1932).
23. Myrmotherula hauxwelli and M. guttata form a superspecies (Haffer 1987, Sibley & Monroe 1990, Zimmer & Isler 2003). They are perhaps not closely related to other Myrmotherula (Hackett & Rosenberg 1990).
23a. The relationships of Myrmotherula gularis are uncertain; often placed with the "stipple-throated group" (see Note 16d), its nest and behavior suggests that it is more closely related to M. hauxwelli and M. guttata (Zimmer & Isler 2003).
23b. Willis (1984b), Ridgely & Tudor (1994), Hilty (2003), and Zimmer & Isler (2003) noted that vocal differences among several subspecies of Myrmotherula axillaris suggest that more than one species is involved.
23c. Vocal, morphological, and behavioral similarities suggest that Myrmotherula schisticolor, M. sunensis, and M. minor may form a monophyletic group (<?>Whitney 1997, Zimmer & Isler 2003).
23d. Called "Black Antwren" in Wetmore (1972).
24. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that Myrmotherula longipennis may consist of more than one species; the subspecies garbei was treated as a separate species from Myrmotherula longipennis by Cory & Hellmayr (1924), but they were treated as conspecific by Peters (1951).
24a. Myrmotherula longipennis and M. urosticta form a superspecies (Zimmer & Isler 2003).
25. Recently described: Gonzaga (1988). Known only from the type specimen, which may be a hybrid M. axillaris X M. unicolor (Gonzaga 1988, Zimmer & Isler 2003).
26. Myrmotherula grisea, M. unicolor, M. snowi, and M. behni seem to form a monophyletic group based on vocalizations and habitat (Whitney 1997, Zimmer & Isler 2003).
26a. Called "Yungas Antwren" in Ridgely & Tudor (1994) and Zimmer & Isler (2003). SACC proposal to change English name to Yungas Antwren did not pass.
27. Recently described (as subspecies of M. unicolor): Teixeira & Gonzaga (1985). See Collar et al. (1992) and Whitney & Pacheco (1997) for elevation to separate species; they constitute a superspecies (Zimmer & Isler 2003).
27a. Herpsilochmus pileatus, H. atricapillus, H. motacilloides, and H. parkeri form a monophyletic group, but in describing sellowi, H. sellowi, Whitney et al. (2000) noted that it might well merit a separate genus because of several unique features. Herpsilochmus atricapillus and H. motacilloides were formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Meyer de Schauensee 1970) considered conspecific with H. pileatus, but see Davis and O'Neill (1986) and Whitney et al. (2000) for treatment of as separate species; Sibley & Monroe (1990) considered these three to form a superspecies.
27b. See Ridgely & Tudor (1994) for use of "Pileated Antwren" for this species.
28. Recently described but nomenclature complex, with H. pileatus actually the "newly discovered" taxon (Whitney et al. 2000).
29. Called "Pileated Antwren" in Ridgely & Tudor (1994). SACC proposal passed to change English name from "Pileated Antwren" to "Bahia Antwren," following Zimmer & Isler (2003).
30. Recently described: Davis and O'Neill (1986).
31. Herpsilochmus dugandi was formerly (e.g., Peters 1951, Meyer de Schauensee 1970) considered a subspecies of H. sticturus, but see Ridgely & Tudor (1994) and Zimmer & Isler (2003); they constitute a superspecies (Zimmer & Isler 2003).
31a. Herpsilochmus stictocephalus was considered to form a superspecies with H. sticturus and H. dugandi by Sibley & Monroe (1990), but see Whitney & Alvarez (1998) for sister relationship to H. gentryi.
31b. Recently described: Whitney & Alvarez (1998).
32. Herpsilochmus pectoralis and H. longirostris were considered to form a superspecies by Sibley & Monroe (1990).
32a. Differences in vocalizations suggest that Herpsilochmus rufimarginatus might consist of more than one species (Zimmer & Isler 2003).
32b. Meyer de Schauensee (1966), Pinto (1978), AOU (1983), Ridgely & Tudor (1994), and Zimmer & Isler (2003) suggested that Microrhopias quixensis might consist of more than one species.
32c. Called "Dotted-winged Antwren" in Wetmore (1972).
33. Cory & Hellmayr (1924) used the name Neorhopias instead of Formicivora for this genus, but see Meyer de Schauensee (1966).
33a. Formicivora iheringi differs in many ways from other species in the genus and may warrant treatment in monotypic genus (Zimmer & Isler 2003).
34. Formicivora erythronotos was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Meyer de Schauensee 1970) placed in the genus Myrmotherula, but see Pacheco (1988) for its return to Formicivora (where it was described).
34a. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that Formicivora grisea may consist of more than one species. Hilty (2003) described major vocal differences between intermedia and grisea in Venezuela and treated them as separate species. proposal needed.
34b. Called "Black-breasted Antwren" in Wetmore (1972).
34c. Recently described: Gonzaga et al. (2007). SACC proposal passed to recognize Formicivora grantsaui.
35. Formicivora serrana, F. littoralis, and F. melanogaster form a superspecies and justification for treating them as species is weak (Pinto & Camargo 1948, Ridgely & Tudor 1994); Zimmer & Isler (2003) considered the first two to form a superspecies but did not include F. melanogaster (but did consider it the sister to F. serrana/F. littoralis.
36. Recently described (as subspecies of F. serrana): Gonzaga & Pacheco (1990). See Collar et al. (1992) and Ridgely & Tudor (1994) for considering it as a separate species from F. serrana.
37. Recently described: Bornschein et al. (1995). Treated in Formicivora by Gonzaga et al. (2007).
37a. Called "Marsh Antwren" in Zimmer & Isler (2003). proposal needed.
37b. Stymphalornis acutirostris probably should be transferred to the genus Formicivora; it may be more closely related to F. rufa and F. grisea than those species are to other Formicivora (REFS, Zimmer & Isler 2003).
38. Drymophila rubricollis was formerly (e.g., Meyer de Schauensee 1970) considered a subspecies of D. ferruginea, but see Willis (1988) for evidence for treating this as a separate species.
38a. Drymophila genei and D. ochropyga are sister species (Zimmer & Isler 2003). 38b. Drymophila devillei and D. caudata are sister species (Zimmer & Isler 2003).
39. Terenura sicki and T. maculata form a superspecies (Zimmer & Isler 2003).
39a. Recently described: Teixeira & Gonzaga (1983).
39b. Called "Alagoas Antwren" in Sibley & Monroe (1990). proposal needed?
39c. Meyer de Schauensee & Phelps (1978) suggested that the Perijá subspecies venezuelana might deserve recognition as a separate species from Terenura callinota.
39cc. Zimmer (1932b) suggested that Terenura callinota and T. humeralis might be conspecific, but they are presumed to be elevationally parapatric, and no intermediate specimens are known. Haffer (1987) proposed that T. callinota and T. spodioptila formed a superspecies. Fjeldså & Krabbe (1990), considered T. callinota and T. sharpei to form a superspecies, as suggested by their parapatry and similar elevational distributions.
39ccc. Called "Rufous-backed Antwren" in Wetmore (1972).
39d. The subspecies sclateri was formerly (e.g., Cory & Hellmayr 1924) treated as a separate species from Cercomacra cinerascens, but they were treated as conspecific by Peters (1951). Zimmer & Isler (2003) suggested that Cercomacra cinerascens may consist of more than one species.
39e. Fitzpatrick & Willard (1990) and Zimmer & Isler (2003) considered Cercomacra tyrannina, C. laeta, C . parkeri, C. nigrescens, and C. serva form a monophyletic group based on plumage and voice. Cercomacra laeta was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Meyer de Schauensee 1970, Ridgely & Tudor 1994) considered conspecific with C. tyrannina, but see Bierregaard et al. (1997) for evidence for treatment as a separate species.
39f. Ridgely & Tudor (1994) proposed that Cercomacra brasiliana may form a superspecies with C. tyrannina and C. laeta. Zimmer & Isler (2003), however, considered its relationships to other Cercomacra uncertain.
39g. Formerly (e.g., Wetmore 1972) known as "Tyrannine antbird.'
41. Recently described: Graves (1997b).
41a. Ridgely & Greenfield (2001) and Zimmer & Isler (2003) suggested that Cercomacra nigrescens may consist of more than one species.
42. Fitzpatrick & Willard (1990), Silva (1992), and Zimmer & Isler (2003) suggested that Cercomacra nigricans, C. carbonaria, C. melanaria, and C. ferdinandi form a monophyletic group based on plumage, voice, and ecology.
42a. Recently described: Fitzpatrick & Willard (1990).
43. The three Pyriglena species constitute a superspecies (Sibley & Monroe 1990, Zimmer & Isler 2003); they have been considered conspecific by some (e.g., Zimmer 1931). See Willis & Oniki (1981) and Ridgely & Tudor (1994) for justification for continued treatment of P. atra as a separate species from P. leuconota, of which it was treated as a subspecies by <check Cory & Hellmayr 1925>, Pinto (1937).
43a. Parker & Carr (1992), Ridgely & Tudor (1994), and Zimmer & Isler (2003) suggested that Pyriglena leuconota might consist of more than one species, but also see Ridgely & Greenfield (2001).
44. Voice and behavior suggest that Pyriglena and Rhopornis are sister genera (Zimmer & Isler 2003).
44a. Rhopornis is masculine, so the correct spelling of the species name is ardesiacus (David & Gosselin 2002b).
44b. Zimmer & Isler (2003) suggested that Myrmoborus leucophrys may consist of more than one species.
44c. Zimmer & Isler (2003) suggested that Myrmoborus myotherinus may consist of more than one species.
45. Genetic data (Bates et al. 1999) indicate suggested that Hypocnemis is most closely related to Drymophila, contrary to its placement in traditional linear sequences. SACC proposal passed to change linear sequence.
45a. Ridgely & Tudor (1994) and Zimmer & Isler (2003) noted that the yellow-bellied (flavescens) subspecies group is almost certainly a separate species from Hypocnemis cantator (as treated by Cory & Hellmayr [1924] and Pinto [1937]). Following Zimmer (1932a), they have been treated as conspecific. Vocal differences and documentation of syntopy and parapatry among taxa formerly ranked as subspecies (Isler et al. 2007) indicate that H. cantator actually consists of at least six species, including H. flavescens. SACC proposal passed to revise species limits.
46. Reasons for treatment of Hypocnemoides melanopogon as a separate species from H. maculicauda are weak (Zimmer 1932a, Ridgely & Tudor 1994, Zimmer & Isler 2003); they form a superspecies (Haffer 1987).
47. Capparella et al. (1997) recommended considering the western subspecies, minor (with jensoni), as a separate species from Percnostola rufifrons, and this was followed by Dickinson (2003); see, however, Isler et al. (2001) and Hilty (2003).
48. Recently described: Isler et al. (2001).
48a. Zimmer & Isler (2003) considered Percnostola rufifrons and P. arenarum to form a superspecies.
49. The taxon Percnostola macrolopha, formerly (e.g., Meyer de Schauensee 1970) considered a distinct species, is a synonym (adult male plumage<?>) of P. lophotes (Parker 1982).
49a. Percnostola lophotes is unlikely to belong in Percnostola (Parker 1982<?>); Cory & Hellmayr (1924) and Zimmer (1932b) placed it in Myrmeciza, but subsequent authors have considered that incorrect.
50. The species in Schistocichla were formerly (e.g., Peters 1951, Meyer de Schauensee 1970, Haverschmidt & Mees 1994) placed in Percnostola, but see Ridgely & Tudor (1994) and Ridgely & Greenfield (2001) for rationale for return to use of Schistocichla for these three species (as in, e.g., Zimmer 1931, Pinto 1937, Phelps & Phelps 1950a). Zimmer & Isler (2003) continued to treat them in Percnostola; see also Braun et al. 2005. Proposal needed? Cory & Hellmayr (1924) placed them in Sclateria.
50a. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that the formerly broadly defined Schistocichla leucostigma probaly consisted of more than one species. Braun et al. (2005) provided evidence that the Tepui taxon saturata deserves species rank. SACC proposal passed to treat saturata as a species. Isler et al. (2007) further showed that the taxa humaythae, brunneiceps, and rufifacies, currently treated as subspecies of P. leucostigma, also warrant species rank. SACC proposal passed to revise species limits.
51. The genus Myrmeciza is widely suspected of being polyphyletic (e.g., Ridgely & Tudor 1994, Zimmer & Isler 2003), and this has been confirmed by recent genetic data (Irestedt et al. 2004). Myrmeciza ferruginea, M. ruficauda, M. loricata, M. squamosa, M. pelzelni, M. hemimelaena, M. atrothorax, and M. griseiceps were formerly (e.g., Cory & Hellmayr 1924) placed in a separate genus, Myrmoderus. Peters (1951) removed all but loricatus and squamosus from Myrmoderus; atrothorax was placed in a separate genus, Myrmophylax, and the rest were transferred to Myrmeciza. Zimmer & Isler (2003) noted that Myrmeciza ferruginea, M. ruficauda, M. loricata, and M. squamosa likely form a monophyletic group based on plumage, voice, and nest structure. Zimmer (1932b) and Meyer de Schauensee (1966, 1970) merged Myrmoderus and Myrmophylax into Myrmeciza. See also Notes 55a and 55b.
51a. Zimmer & Isler (2003) suggested that Myrmeciza longipes may consist of more than one species.
51b. Pinto (1978) suggested that Myrmeciza loricata and M. squamosa should be considered conspecific, but see Ridgely & Tudor (1994); they form a superspecies (Zimmer & Isler 2003).
51c. Myrmeciza laemosticta and M. nigricauda form a superspecies (Zimmer & Isler 2003).
51d. Formerly (e.g., Wetmore 1972) called "Salvin's Antbird."
52. Sipia rosenbergi was formerly (e.g., Cory & Hellmayr 1924 Peters 1951, Meyer de Schauensee 1970) considered a separate species ("Esmeraldas Antbird") from Myrmeciza ("Sipia") berlepschi, but Robbins and Ridgely (1991) showed that this taxon is a synonym of M. laemosticta nigricauda; thus, the species Sipia rosenbergi becomes M. nigricauda.
52a. Myrmeciza berlepschi was formerly (e.g., Peters 1951, Meyer de Schauensee 1970) treated in a separate genus, Sipia, along with "Sipia rosenbergi" (see note 52). The genus Sipia, however, is not diagnosable and was merged into Myrmeciza by Robbins and Ridgely (1991).
53. SACC proposal passed to recognize Myrmeciza castanea as a species distinct from M. hemimelaena, following Isler et al. (2002).
53a. SACC proposal passed to retain long-standing "Chestnut-tailed Antbird" for M. hemimelaena, and to coin new name, "Zimmer's Antbird" (after John T. Zimmer, who described this taxon as a species), for M. castanea, rather than adopt the English names "Northern Chestnut-tailed Antbird" for Myrmeciza castanea and "Southern Chestnut-tailed Antbird" for Myrmeciza hemimelaena, as in Zimmer & Isler (2003).
54. "Myrmeciza stictothorax" was formerly (e.g., Peters 1951, Meyer de Schauensee 1970, Sibley & Monroe 1990) considered a separate species ("Spot-breasted Antbird") or as a subspecies of M. atrothorax (e.g, Pinto 1937), but see Schulenberg & Stotz (1991) for reasons for considering it a synonym of M. atrothorax melanura.
55. Myrmeciza melanoceps and M. goeldii were considered to form a superspecies by Parker (1982), Haffer (1987), and Sibley & Monroe (1990).
55a. Zimmer & Isler (2003) suggested that Myrmeciza immaculata and M. fortis might form a superspecies.
55b. Myrmeciza disjuncta may not belong in Myrmeciza but rather in Sclateria ( Ridgely & Tudor 1994, Hilty 2003); Zimmer & Isler (2003) considered its relationships to other Myrmeciza uncertain.<see recent Zimmer paper>
55c. Myrmeciza griseiceps may not belong in Myrmeciza but rather in Cercomacra or a monotypic genus (Zimmer 1932b, Ridgely & Tudor 1994, Ridgely & Greenfield 2001); Zimmer & Isler (2003) considered its relationships to other Myrmeciza uncertain but possibly related to M. nigricauda.
55d. Although its terrestrial morphology recalls an antpitta (Formicariidae), voice and plumage suggest that Myrmornis torquata is a member of the Thamnophilidae, perhaps closest to Myrmeciza (Schwartz & Lentino 1984). Zimmer & Isler (2003), however, suggested that its inclusion in the Thamnophilidae was in need of reappraisal.
55e. Ridgely & Tudor (1994) and Zimmer & Isler (2003) suggested that Myrmornis torquata may consist of more than one species; Cory & Hellmayr (1924) treated the subspecies stictoptera of Central America and western Colombia as a separate species.
55f. Myrmornis torquata was formerly (e.g., Phelps & Phelps 1950a) listed as Rhopoterpe torquata, but see <REF>. 56. Pithys castaneus, until recently known only from the type specimen, has been suspected of being an aberrant P. albifrons or a hybrid (Willis 1984c), but Lane-Valqui-Alvarez (MS) have discovered populations in northeastern Peru and have shown that it is a valid species. Whether it belongs in Pithys is uncertain (Zimmer & Isler 2003; cf. Bond 1951a).
56b. Pithys is masculine, so the correct spelling of the species name is castaneus (David & Gosselin 2002b).
57. Willis (1967) suggested that trans-Andean bicolor subspecies group deserved separate species, and this was followed by Wetmore (1972), Hilty & Brown (1986), and Sibley & Monroe (1990), returning to the species limits of Cory & Hellmayr (1924). See Hackett (1993) for continued treatment of bicolor as conspecific with G. leucaspis, as outlined by Zimmer (1937a).
57a. Gymnopithys leucaspis and G. rufigula form a superspecies (Zimmer & Isler 2003).
57b. Gymnopithys lunulatus and G. salvini are sister species (Zimmer 1937a) that form a superspecies (Sibley & Monroe 1990, Zimmer & Isler 2003). <check Hackett on rufigula>
57c. Gymnopithys is masculine, so the correct spelling of the species name is lunulatus; rufigula, however, is invariable (David & Gosselin 2002b).
58. The five species of Rhegmatorhina form a superspecies (Haffer REF, Sibley & Monroe 1990).
58a. Ridgely & Tudor (1994) suggested that the subspecies brunneiceps might deserve recognition as a separate species from Rhegmatorhina melanosticta; Zimmer & Isler (2003) suggested that R. melanosticta may consist of more than one species..
58b. Rhegmatorhina melanosticta was formerly (e.g., Cory & Hellmayr 1924) placed in the genus Gymnopithys, but see Zimmer (1932b) for its transfer to Rhegmatorhina, which has been followed in all subsequent classifications.
59. Hylophylax naevioides and H. naevius were considered to form a superspecies by the AOU (1983, 1998).
59b. Hylophylax is masculine, so the correct spellings of the species names are naevius, punctulatus, and poecilinotus (David & Gosselin 2002b); the correct spelling of the latter is poecilinota (now poecilinotus), not poecilonota (e.g., as in Meyer de Schauensee 1970, Haverschmidt & Mees 1994).
59c. Zimmer & Isler (2003) suggested that Hylophylax naevius may consist of more than one species.
60. Pinto (1978) treated lepidonota (with duidae) as a separate species, and Hilty (2003) and Zimmer & Isler (2003) suggested that more than one species was involved; however, see Zimmer (1934d), Willis (1982), and Ridgely & Tudor (1994).
60a. Ridgely & Tudor (1994) suggested that Dichropogon (Hylophylax) poecilinotus might belong in Hypocnemoides; Zimmer & Isler (2003) also suggested that it might not be closely related to other Hylophylax. Brumfield et al. (2007) have shown that its inclusion in Hylophylax makes it a paraphyletic taxon. SACC proposal passed to revive genus Dichropogon. Dichropogon, however, is preoccupied by a genus of asilid fly, and Agne & Pacheco (2007) proposed Willisornis as a new name. SACC proposal passed to replace with Willisornis.
61. The taxon "Phlegopsis barringeri", formerly (e.g., Meyer de Schauensee 1970) considered a valid species, was shown to be a hybrid P. erythroptera X P. nigromaculata by Graves (1992), as suspected by Willis (1979).
62. Skutchia borbae was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951) placed in the genus Phlegopsis, but see <REFs>, Zimmer & Isler (2003).
62a. Formerly (e.g., Meyer de Schauensee 1970, Sibley & Monroe 1990, Dickinson 2003) known as "Pale-faced Bare-eye." Called "Pale-faced Antbird" in Willis (1968), Ridgely & Tudor (1994), and Zimmer & Isler (2003) to emphasize that it does not belong in the genus Phlegopsis. SACC proposal passed to change English name from "Bare-eye" to "Antbird".

1. This family is separated from the Thamnophilidae following Sibley & Ahlquist (1990), Sibley & Monroe (1990), Harshman (1994), Ridgely & Tudor (1994), AOU (1998), and Zimmer & Isler (2003). Genetic data (Chesser 2004) indicate that it is more closely related to the Rhinocryptidae + Furnariidae than to the Thamnophilidae. Genetic data (Irestedt et al. 2002, Chesser 2004, Rice 2005b) also indicate that the Formicariidae itself is not monophyletic: Formicarius, the type genus for the family, and Chamaeza are more closely related to the furnariidae and Rhinocrpytidae than to a group that includes Grallaria, Grallaricula, and Myrmothera. Genetic data (Rice 2005a, b) also indicate that Pittasoma is more closely related to the Conopohagidae than to the Grallaria group. SACC proposal passed to create new family for Grallaria group and to transfer Pittasoma to Conopophagidae.
1a. The ruficeps subspecies group was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951) considered a separate species from Formicarius colma, but they were treated as conspecific by Meyer de Schauensee (1966, 1970).
1b. Formicarius analis may include two or three taxa that deserve recognition as separate species (Howell 1994, Krabbe & Schulenberg 2003a); Krabbe & Schulenberg (2003a) treated the northern subspecies group as a separate species, F. moniliger. proposal needed.
1c. Krabbe & Schulenberg (2003a) suggested that Chamaeza campanisona may consist of up to four separate species.
1d. Chamaeza campanisona was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937) known as C. brevicauda, but see Peters (1951).
1e. SACC proposal to change English names of species in Formicarius and Chamaeza to "Ant-thrush" did not pass.
2. Krabbe & Schulenberg (2003a) suggested that the southeastern subspecies fulvipectus deserves recognition as a separate species from Chamaeza nobilis.
2a. Called "Noble Antthrush" in Ridgely & Tudor (1994), but Ridgely & Greenfield (2001) reverted to "Striated Antthrush."
3. Chamaeza meruloides was formerly (e.g., REFS) considered conspecific with C. ruficauda, but see <REFS>.
3a. Called "Cryptic Antthrush" in Ridgely & Tudor (1994) and Krabbe & Schulenberg (2003a). SACC proposal to change to "Cryptic Antthrush" did not pass.
4. Chamaeza turdina was formerly (e.g., Cory & Hellmayr 1924, Peters 1951, Meyer de Schauensee 1970) considered conspecific with C. ruficauda, but see (REFS).
4a. Called "Scalloped Antthrush" in Sibley & Monroe (1990) and Ridgely & Tudor (1994). SACC proposal to change to "Scalloped Antthrush" did not pass.
4aa. Called "Brazilian Antthrush" in Sibley & Monroe (1990), Sick (1993), and Clements (2000). SACC proposal to change to "Brazilian Antthrush" did not pass.
4b. Fjeldså (1992) proposed that Grallaria squamigera and G. gigantea were sister species, based on plumage similarities, as reflected in their placement in traditional linear sequences. Hilty (2003) and Krabbe & Schulenberg (2003a) suggested that Grallaria excelsa and G. gigantea may be conspecific. Krabbe & Schulenberg (2003a) further suggested that the subspecies lehmani, currently treated within G. gigantea, could be placed in G. excelsa, or that the subspecies hylodroma, currently treated within G. gigantea, should be treated as a separate species. Rice (2005) found that G. squamigera and G. varia were sister taxa (G. gigantea not sampled) that form a group basal to all other Grallaria.
4bb. <REFS> suggested that the subspecies imperator (with intercedens) might deserve recognition as a separate species from Grallaria varia, but see Krabbe & Schulenberg (2003a).
4c. Hilty (2003) noted that Grallaria chthonia is extremely similar to G. guatimalensis and may be only a subspecies of that species. Krabbe & Schulenberg (2003a) considered Grallaria chthonia and G. alleni to be more closely related.
4d. Grallaria dignissima was formerly (e.g., Cory & Hellmayr 1924, Zimmer 1937a, Peters 1951, Meyer de Schauensee 1966) placed in the genus Thamnocharis, but see Lowery & O'Neill (1969) for its merger into Grallaria.
4e. Grallaria guatimalensis and G. alleni form a superspecies; they may be better treated as conspecific (Sibley & Monroe 1990). [incorp. Krabbe & Coopmans (2000)]
4f. Grallaria dignissima and G. eludens form a superspecies (Haffer 1987, Sibley & Monroe 1990, Krabbe & Schulenberg 2003a); genetic data (Rice 2005) indicate that they are sister species.
6. Grallaria watkinsi was formerly (e.g., Zimmer 1934, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of G. ruficapilla, but Parker et al. (1995) <check>, Ridgely & Greenfield (2001), and Krabbe & Schulenberg (2003a) considered watkinsi a separate species primarily because of their songs differ strongly, thus returning to the species limits of Chapman (1919) and Cory & Hellmayr (1924); they form a superspecies (Sibley & Monroe 1990). See Zimmer (1934) for the original rationale for treatment of watkinsi as conspecific with G. ruficapilla. proposal needed.
7. Recently described: Stiles (1992).
8. Krabbe & Schulenberg (2003a) suggested that Grallaria andicolus is not particularly closely related to other Grallaria species and may warrant treatment in monotypic genus.
8a. The southern subspecies punensis was formerly (e.g., Cory & Hellmayr 1924) considered a separate species from Grallaria andicolus, but Peters (1951) treated them as conspecific; Krabbe & Schulenberg (2003a) noted that vocal differences suggest that punensis should be treated as a separate species.
8b. Correct spelling for species name is andicolus (David & Gosselin 2002a).
8c. Based on shared plumage features, Zimmer (1934d) proposed that Grallaria rufocinerea and G. erythroleuca were sister species.
9. Recently described: Krabbe et al. (1999).
9a. Grallaria nuchalis and G. carrikeri form a superspecies (Schulenberg & Williams 1982, Parker et al. 1985, Sibley & Monroe 1990).
9b. The northern subspecies ruficeps was formerly (e.g., Cory & Hellmayr 1924) considered a separate species from Grallaria nuchalis, but they were treated as conspecific by Peters (1951). Krabbe & Schulenberg (2003a) noted that vocal differences suggest that the subspecies obsoleta deserves recognition as a separate species from G. nuchalis.
10. Recently described: Schulenberg & Williams (1982).
10a. Krabbe & Schulenberg (2003a) suggested that Grallaria albigula might be part of the G. hypoleuca superspecies (see Note 12); see Zimmer (1934d) for rationale for a close relationship to the G. nuchalis group.
11. Grallaria flavotincta was formerly (e.g., Peters 1951, Meyer de Schauensee 1966, 1970) considered a subspecies of G. hypoleuca, but Hilty & Brown (1986)<check>, Sibley & Monroe (1990), Ridgely & Tudor (1994), Ridgely & Greenfield (2001), and Krabbe & Schulenberg (2003a) considered flavotincta a separate species because of slight differences in voice, thus returning to the species limits of Cory & Hellmayr (1924). proposal needed.
12. Grallaria hypoleuca (with flavotincta), G. przewalskii, G. erythroleuca, and G. capitalis were considered conspecific ("Bay-backed Antpitta") by Meyer de Schauensee (1970) but not by Peters (1951) or Meyer de Schauensee (1966) or any recent authors; they constitute a superspecies (Sibley & Monroe 1990, Krabbe & Schulenberg 2003a). See also Note 8c.
13. Geographic variation in song strongly suggests that Grallaria rufula includes more than one species (Krabbe & Schulenberg 2003a). Hilty (2003) noted that plumage and size differences alone suggest that saltuensis from the Perijá Mountains may be a separate species, and Krabbe & Schulenberg (2003a) suggested that saltuensis might be more closely related to G. quitensis.
14. Recently described: Graves (1987).
14a. Krabbe & Schulenberg (2003a) considered Grallaria blakei and G. rufula to form a superspecies; genetic data (Rice 2005) are consistent with their treatment as sister species.
14a. Krabbe & Schulenberg (2003a) noted that vocal differences suggest that the subspecies alticola and atuensis each deserves recognition as a separate species from Grallaria quitensis.
15. See Lowery & O'Neill (1969) for recognition of Hylopezus as a separate genus from Grallaria, in which it was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951, Meyer de Schauensee 1966) included. In fact, genetic data (Rice 2005) indicate that Hylopezus is the sister genus to Myrmothera, not to Grallaria.
15a. Called "Spectacled Antpitta" in AOU (1983), Ridgely & Gwynne (1989), and Stiles & Skutch (1989).
16. Hylopezus auricularis was formerly (e.g., Peters 1951, Phelps & Phelps 1950a, Meyer de Schauensee 1970) considered a subspecies of H. macularius, but Maijer (1998) provided evidence from vocalizations that it warrants recognition as a separate species; they form a superspecies. Additional species may be involved within macularius (Hilty 2003, Krabbe & Schulenberg 2003a).
17. Hylopezus dives was formerly (e.g., Cory & Hellmayr 1924, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of H. fulviventris, but evidence from vocalizations (REFS, Ridgely & Tudor 1994) indicates that it warrants recognition as a separate species; they form a superspecies with H. berlepschi (Sibley & Monroe 1990). Krabbe & Schulenberg (2003a) noted that vocal similarities between H. fulviventris and H. berlepschi suggest that they might be conspecific.
18. Hylopezus dives was called "Fulvous-bellied Antpitta", the name for the former composite species (dives + fulviventris), by Ridgely & Tudor (1994). The AOU (1998) coined "Thicket Antpitta" not only to emphasize the species split but also to avoid use of "Fulvous-bellied" for H. dives when the species name for White-lored is fulviventris. proposal needed?
19. Hylopezus nattereri was formerly (e.g., Peters 1951, Meyer de Schauensee 1970) considered a subspecies of H. ochroleucus, but Whitney et al. (1995) provided evidence from differences in vocalizations, habitat, and plumage that it warrants recognition as a separate species, a return to the classification of Pinto (1937); they form a superspecies (Sibley & Monroe 1990).
19a. Krabbe & Schulenberg (2003a) suggested that the southeastern subspecies subcanescens deserves recognition as a separate species.
20. Formerly (e.g., Meyer de Schauensee 1970) called "Brown-breasted Antpitta," but see Ridgely & Tudor (1994). proposal needed?
20a. The subspecies boliviana (with similis) was formerly (e.g., REF) considered a separate species from Grallaricula flavirostris.
20aa. Called "Ochraceous Pygmy Antpitta" in Wetmore (1972).
20b. Meyer de Schauensee (1966) suggested that Grallaricula peruviana might be best treated as a subspecies of G. loricata.
20c. Grallaricula peruviana and G. ochraceifrons were considered to form a superspecies by Parker et al. (1985) and Sibley & Monroe (1990).
21. Recently described: Graves et al. (1983).
22. The subspecies rara was formerly (e.g., Cory & Hellmayr 1924) treated as a separate species from Grallaricula ferrugineipectus, but Peters (1951) treated them as conspecific. Ridgely & Tudor (1984) suspected that G. ferrugineipectus might consist of more than one species. Krabbe & Schulenberg (2003a) indicated that vocal differences suggest that the southern subspecies leymebambae deserves recognition as a separate species.
23. (REF) proposed that the subspecies of the coastal mountains of Venezuela deserve recognition as a separate species from Grallaricula nana, but voices evidently similar (Krabbe & Schulenberg 2003a).
24. Parker et al. (1985) proposed that Grallaricula nana and G. ferrugineipectus formed a superspecies.

CONOPOPHAGIDAE (GNATEATERS) 1

Conopophaga ardesiaca Slaty Gnateater
Conopophaga melanops Black-cheeked Gnateater
Pittasoma michleri Black-crowned Antpitta
Pittasoma rufopileatum Rufous-crowned Antpitta


1. The Conopophagidae have sometimes been treated in the Formicariidae sensu lato (e.g., Ames 1968, Meyer de Schauensee 1970). [recent data] <incorp. Whitney 2003> Genetic data (Chesser 2004) indicate that they are the sister group to the Thamonophilidae. Proposal needed to change linear sequence of families. Rice (2005a, b) found that Pittasoma was the sister txon to Conopophaga; therefore, Rice (2005b) advocated inclusion of Pittasoma in the Conopophagidae. SACC proposal passed to include Pittasoma in the Conopophagidae.
2. The subspecies cearae of northeastern Brazil was formerly (e.g., Cory & Hellmayr 1924, Pinto 1937, Peters 1951) considered a separate species from Conopophaga lineata, but most authors have followed Pinto & Camargo (1961) and Meyer de Schauensee (1966) in considering them conspecific. Vocal differences between cearae and other populations of C. lineata suggest that it deserves a return to species rank (Whitney 2003).
3. Conopophaga aurita almost certainly consists of more than one species (Whitney 2003).
4. Conopophaga aurita was formerly (e.g., Cory & Hellmayr 1924) known as C. snethlageae, but aurita has priority (see Peters 1951).

1. [family relationships, linear sequence; undescribed species]. Genetic data (Chesser 2004) indicate that the Rhinocryptidae are most closely related to a group that includes Formicarius and Furnariidae sensu lato. Proposal needed to change linear sequence of families. Genetic data (Irestedt et al., Chesser 2004) also indicate that Melanopareia does not belong in the Rhinocryptidae. SACC proposal passed to create new family.
2. See Howell & Webb (1995) and Chesser (1999) for evidence for continued recognition of Pteroptochos castaneus and P. tarnii as separate species; they were considered conspecific by Fjeldså & Krabbe (1990) and Sibley & Monroe (1990); they form a superspecies (Krabbe & Schulenberg 2003b).
3.
4. Psilorhamphus formerly had been placed by some in the Formicariidae (e.g., Cory & Hellmayr 1924, Pinto 1937), and Peters (1951) proposed that it belonged in the Sylviidae, but its position in the Rhinocryptidae has not been questioned since Plotnik (1958) and Sick (1960).
4a. SACC proposal passed to delete hyphen from English name "Bamboo-wren."
4b. Merulaxis stresemanni and M. ater form a superspecies (Krabbe & Schulenberg 2003b).
4c. Eugralla has priority over Triptorhinus, the name used by Cory & Hellmayr (1924).
5. REFS, and Hilty & Brown (1986) considered Myornis not worthy of recognition in a monotypic genus, but see Fjeldså & Krabbe (1990) for continued recognition of the genus. <REF> included it within Scytalopus, but see Krabbe & Schulenberg (2003b).
6. Scytalopus latrans was formerly (e.g., Zimmer 1939x, Phelps & Phelps 1950a, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of S. unicolor; for treatment as a separate species from S. unicolor based on differences in voice, see Krabbe & Schulenberg (1997) and Coopmans et al. (2001); it had previously been considered a separate species by Cory & Hellmayr (1924).
7. Krabbe & Schulenberg (1997) and Ridgely & Greenfield (2001) suggested that the subspecies subcinereus might deserve recognition as a separate species from Scytalopus latrans.
8. Formerly much more broadly defined; see Krabbe & Schulenberg (1997) and Coopmans et al. (2001).
9. Scytalopus parvirostris was described as (Zimmer 1939x) and formerly (e.g., Peters 1951, Meyer de Schauensee 1970) considered a subspecies of S. unicolor; for treatment as a separate species from S. unicolor based on differences in voice, see Krabbe & Schulenberg (1997).
9a. Krabbe & Schulenberg (2003b) considered Scytalopus speluncae and S. iraiensis to be sister species. Bornschein et al. (2007) found that thesongs of these two species did not differ. Proposal needed to re-evaluate species rank of iraiensis.
9b. Recently described: Maurício (2005). Scytalopus pachecoi populations were formerly included in S. speluncae, but the two differ in voice and are locally sympatric Maurício (2005). SACC proposal passed to recognize S. pachecoi.
9c. Raposo et al. (2006) have described a new species, S. notorius, most closely related to S. speluncae, and have redescribed S. speluncae. Proposal badly needed.
9d. Bornschein et al. (2007) have described a new species, S. diamantinensis, most closely related to S. pachecoi and S. novacapitalis. SACC proposal to recognize diamantinensis as a species did not pass.
10. Recently described: Bornschein et al. (1998).
10b. Zimmer (1939x) suspected that Scytalopus macropus was most closely related to his broadly defined Scytalopus unicolor based on structural proportions, bill shape, and plumage.
11. Scytalopus sanctaemartae was formerly (e.g., Zimmer 1939x, Peters 1951, Meyer de Schauensee 1970) considered a subspecies of S.
