Proposal (746) to South American Classification Committee

 

Remove Arremon crassirostris from Hypothetical List to Main List

 

Effect on South American CL: This transfers a species from our Hypothetical List to the Main List.

 

Background: The Hypothetical List currently reads as follows:

 

Sight reports from Colombian side of Cerro Tacarcuna (see Ridgely & Tudor 1989; no specimens collected, fide Daniel Cadena).

 

New information: Renjifo et al. (2017) presented photos of two A. crassirostris specimens collected in 1980 at the east foothills of Cerro Tacarcuna in Colombia. Both specimens are currently deposited at Instituto Alexander von Humboldt, Villa de Leyva (IAvH-A 3164, 3174). They also reported a third specimen collected on 2008 at r’o Tanelita, east slope of Cerro Tacarcuna, which is deposited at Instituto de Ciencias Naturales, Bogot‡ (ICN 37368). All specimens exhibit the conspicuous white malar stripe and yellow patch on the central underparts typical of the species.

Recommendation: I recommend a yes vote to include the species on the Main List and remove it from the Hypothetical List.
