status

 

Grallaria cochabambae Bond & Meyer de Schauensee, 1940  , subspecies elevated to species

Bolivian Antpitta

Includes population designated cochabambae  2 in the analysis.

Diagnosis. Upperparts dark reddish yellow-brown; underparts paler grading to pale buffy brown on center of belly and undertail coverts; pale feather edgings and pencil streaks on belly; pale eye-ring. Short songs of two unmodulated notes distinguish G. cochabambae  ( Fig. 18View FIGURE 18) from all other populations except G. sinaensis  and the nominate form of G. occabambae  . The flat or slightly downslurred shape of short song notes of G. cochabambae  distinguishes them from the rounded notes of those of G. occabambae  . The internote interval of short songs of G. cochabambae  is significantly longer than that of G. sinaensis  and significantly shorter than that of G. occabambae  . Long songs of G. cochabambae  differ from those of G. sinaensis  and G. occabambae  in their sharply downslurred note shape and in their significantly faster pace. They differ from long songs of G. occabambae  by their falling and rising frequency pattern and by their duration pattern, in which notes lengthen, become even, and shorten while intervals remain more constant. They differ from long songs of G. sinaensis  by the lesser extent that frequency rises in the terminal half of the song.

Distribution. Endemic to Bolivia in eastern La Paz and Cochabamba, 2950–3500 m.

Plumage. Overall plumage of upperparts, including rectrices, remiges (primaries edged paler), crown and auriculars, dark reddish yellow-brown (7.5YR 4/4), shading to color of underparts in malar area; eye-ring pale. Throat and breast reddish-yellow-brown (7.5YR 5/8–5/6); belly and undertail coverts pale buffy brown (10YR 7/4), pale feather edgings and pencil streaks restricted to belly; flanks dark reddish yellow brown (7.5 5/4) (specimen photographs App. 6, Fig. A32).

Etymology. The English name refers to the country to which this species is endemic. The name was also used by Krabbe et al. (2019).

Remarks. The type locality (Incachaca, Cochabamba) of G. rufula cochabambae  falls within the geographic range of this species.
