Proposal (594) to South American Classification Committee
Revise linear
sequences of species in Geositta,
Cinclodes, and Phacellodomus
This
set of proposals would make minor “book-keeping” modifications the linear
sequences of species in 3 genera in the Furnariidae to reflect relationships
shown by Derryberry et al. (2011), who sampled the family intensively (97% of
all species). The gene-sampling was also
intensive: “For the majority of individuals, we amplified and sequenced
three mitochondrial genes and one nuclear intron: NADH dehydrogenase subunit 3
(ND3; 351 bp), cytochrome oxidase subunit 2 (CO2; 684 bp), NADH dehydrogenase
subunit 2 (ND2; 1041 bp), and β-fibrinogen intron 7 (Bf7; ∼840 bp). For at
least one individual per genus, we also included a large portion of the single
exons of the recombination activating genes RAG-1 (2904bp) and RAG-2 (1152bp).” I have packaged
them all into a single proposal with multiple parts because they are all based
on Derryberry et al. (2011). The
sequences use the standard conventions, i.e., least-diverse (# taxa at same
rank) branch first, sister taxa or allospecies in superspecies listed
geographically, NW to SE; tabs used to signify nodes, and spaces aid in marking
sister species:
A. Geositta: Our current linear sequence
is based on Cheviron et al. (2005).
Geositta peruviana Coastal
Miner
Geositta cunicularia Common Miner
Geositta tenuirostris Slender-billed Miner
Geositta antarctica Short-billed Miner
Geositta isabellina Creamy-rumped Miner
Geositta saxicolina Dark-winged Miner
Geositta maritima Grayish Miner
Geositta punensis Puna Miner
Geositta rufipennis Rufous-banded Miner
Geositta poeciloptera Campo Miner
Geositta crassirostris Thick-billed Miner
New
information:
Derryberry et al. (2011) produced a phylogenetic hypothesis for the entire
family Furnariidae based on multiple loci and an almost complete sampling of
the family at the species level. The
tree was largely in agreement with the mtDNA-based tree of Cheviron et al.
(2005) with one exception: Geositta punensis was found to be the
sister species of G. cunicularia
rather than a member of the group of species rather than part of the group that
includes G. poeciloptera + G. crassirostris + G.
rufipennis. The
relevant section of the tree from Derryberry et al. (2011) is pasted in below.
To have our sequence reflect the phylogeny in
Derryberry et al. (2011), G. punensis
has to be moved adjacent to G.
cunicularia. As long as that move
needs to be made, we might as well make minor adjustments to the rest of the
sequence to follow the standard conventions:
Geositta peruviana Coastal
Miner
Geositta
tenuirostris Slender-billed Miner
Geositta
cunicularia Common Miner
Geositta
punensis Puna Miner
Geositta poeciloptera
Campo Miner
Geositta
crassirostris Thick-billed Miner
Geositta
rufipennis Rufous-banded Miner
Geositta maritima Grayish
Miner
Geositta
antarctica Short-billed Miner
Geositta
saxicolina Dark-winged Miner
Geositta
isabellina Creamy-rumped Miner
Analysis
and Recommendation: The proposed new sequence reflects the
findings of Derryberry et al. (2011) using sequencing conventions. This is all minor stuff, but as long as we’re
going to use linear sequences to reflect phylogeny, we have to pay attention to
these details, so I recommend a YES on this.
B.
Cinclodes: Our current sequence is based on Chesser
(2004) and SACC proposal 414.
Cinclodes
pabsti
Long-tailed Cinclodes
Cinclodes antarcticus Blackish Cinclodes
Cinclodes fuscus Buff-winged Cinclodes
Cinclodes albidiventris Chestnut-winged Cinclodes
Cinclodes comechingonus Cordoba Cinclodes
Cinclodes albiventris Cream-winged Cinclodes
Cinclodes olrogi Olrog's Cinclodes
Cinclodes excelsior Stout-billed Cinclodes
Cinclodes aricomae Royal Cinclodes
Cinclodes atacamensis White-winged Cinclodes
Cinclodes palliatus White-bellied Cinclodes
Cinclodes oustaleti Gray-flanked Cinclodes
Cinclodes patagonicus Dark-bellied Cinclodes
Cinclodes taczanowskii Surf Cinclodes
Cinclodes nigrofumosus Seaside Cinclodes
Derryberry
et al. (2011), with broader genetic and taxon sampling, found a slightly
different branching pattern:
A
sequence modified to reflect these relationships is below:
Cinclodes pabsti Long-tailed Cinclodes
Cinclodes fuscus Buff-winged
Cinclodes
Cinclodes antarcticus Blackish
Cinclodes
Cinclodes comechingonus Cordoba
Cinclodes
Cinclodes albidiventris Chestnut-winged
Cinclodes
Cinclodes olrogi Olrog's
Cinclodes
Cinclodes albiventris Cream-winged
Cinclodes
Cinclodes oustaleti Gray-flanked
Cinclodes
Cinclodes excelsior Stout-billed
Cinclodes
Cinclodes aricomae Royal Cinclodes
Cinclodes palliatus White-bellied
Cinclodes
Cinclodes atacamensis White-winged
Cinclodes
Cinclodes patagonicus Dark-bellied
Cinclodes
Cinclodes taczanowskii Surf
Cinclodes
Cinclodes nigrofumosus Seaside
Cinclodes
Analysis
& Recommendation:
The above sequence reflects the new findings of Derryberry et al. (2011). Frankly, the sequence from fuscus through oustaleti is baffling to me biogeographically and from what little
I thought I knew about the birds.
Nonetheless, the genetic data are solid and largely match those of Sanín
et al. (2009), and so I recommend a YES.
C.
Phacellodomus: Our current
sequence is:
Phacellodomus
rufifrons
Rufous-fronted Thornbird
Phacellodomus sibilatrix Little Thornbird
Phacellodomus striaticeps Streak-fronted
Thornbird
Phacellodomus maculipectus Spot-breasted
Thornbird
Phacellodomus striaticollis Freckle-breasted
Thornbird
Phacellodomus dorsalis Chestnut-backed
Thornbird
Phacellodomus ruber Greater Thornbird
Phacellodomus erythrophthalmus Orange-eyed
Thornbird
Phacellodomus ferrugineigula Orange-breasted Thornbird
Our
current note covers the problem:
73. Phacellodomus maculipectus was
formerly (e.g., Peters, 1951, Meyer de Schauensee 1970) considered a subspecies
of P. striaticollis. Ridgely & Tudor (1994), based on Nores
and Yzurieta (1979<check>), considered the subspecies maculipectus
to be a separate species from striaticollis. SACC
proposal passed to recognize maculipectus as a separate
species. Derryberry et al. (2011) found that they were not sister taxa,
with P. striaticollis
the sister to P. ruber, and P. maculipectus sister
to P. dorsalis. SACC proposal needed to change linear sequence.
Derryberry
et al. (2011) found the following branching pattern:
The following modification corrects our
sequence, namely to show that P. maculipectus
and P. striaticollis are not sisters:
Phacellodomus rufifrons Rufous-fronted
Thornbird
Phacellodomus striaticeps Streak-fronted
Thornbird
Phacellodomus sibilatrix Little
Thornbird
Phacellodomus dorsalis Chestnut-backed
Thornbird
Phacellodomus maculipectus Spot-breasted
Thornbird
Phacellodomus striaticollis Freckle-breasted
Thornbird
Phacellodomus ruber Greater
Thornbird
Phacellodomus erythrophthalmus Orange-eyed
Thornbird
Phacellodomus ferrugineigula Orange-breasted
Thornbird
Analysis
& Recommendation:
The above sequence reflects the new findings of Derryberry et al. (2011), who
did not sample Phacellodomus ferrugineigula, but a safe assumption is that it is sister to P. erythrophthalmus, with
which it was considered conspecific until recently. The genetic data are solid and the nodes all
have strong support; so I recommend a YES.

Comments from Stiles: “YES. Given the
now solid genetic data and the use of standard conventions, I see no problem with
rearranging the sequences of species in these genera to accord with these data.”
Comments from Zimmer: “YES, on all three
sub-proposals, to reflect the most current genetic data.”
Comments from Pacheco: “Eu decido meus votos seguindo as expressas recomendações
de Remsen por refletirem de forma mais ampla as filogenias apresentadas:
[YES] to A, B, and C.”
Comments
from Pérez-Emán: “YES
to all sub-proposals to incorporate the most recent phylogenetic information.”
Comments
from Jaramillo: “A –
Revise linear order in Geositta as
stated in the proposal. YES.
B – Revise
linear order of Cinclodes. YES. An aside, this is a prediction, but Fuegian antarcticus, is likely from the patagonicus clade. Probably quite
unrelated to Falkland antarcticus.
Unfortunately genetic and vocal data for that population are essentially
unknown, we shall have to wait for data to emerge at some point.
C – Revise
linear order in Phacellodomus. YES.
