Woodpeckers (Picidae)

White-wedged Piculet (Picumnus albosquamatus) - HBW 7, p. 429

French: Picumne noir et blanc German: Weißschuppen-Zwergspecht Spanish: Carpinterito Albiescamoso
Other common names: Guttate Piculet (guttifer); Blackish Piculet (“P. asterias”)

Taxonomy: Picumnus albosquamatus d’Orbigny, 1840, Río Tamanipaya, Yungas, Bolivia.
Hybridizes with P. dorbignyanus, also to limited extent with P. cirratus, and occasionally with P. temminckii. Race guttifer formerly considered a separate species, but appears to intergrade with nominate in W Mato Grosso; these mixed populations probably account for the form previously listed as race P. a. corumbanus. Forms described as species “P. asterias”, known only from single type specimen, and “P. sagittatus” are indistinguishable from variable race guttifer, and are thus synonymized with it.

Taxonomy: Picumnus albosquamatus d’Orbigny, 1840, Río Tamanipaya, Yungas, Bolivia.

Race guttifer formerly considered a separate species, but appears to intergrade with nominate in W Mato Grosso; these mixed populations probably account for the form previously listed as race P. a. corumbanus. Forms described as species “P. asterias”, known only from single type specimen, and “P. sagittatus” are indistinguishable from variable race guttifer, and are thus synonymized with it. Two subspecies currently recognized.

Subspecies and Distribution:

  • guttifer Sundevall, 1866 - E & C Brazil, from S Pará and S Maranhão S to S & E Mato Grosso and W São Paulo.
