Taxonomic review of the rhinocryptid genus Eleoscytalopus (I): Bahia Tapaculo (E. psychopompus) is vocally and morphologically distinct from White-breasted Tapaculo (E. indigoticus)

The Bahia Tapaculo (Eleoscytalopus psychopompus) is a rare taxon endemic to a narrow strip of lowland Atlantic Forest in the coast of Bahia, Brazil. Its phenotypic distinction from its sister species, the White-breasted Tapaculo (E. indigoticus), has been considered doubtful because the supposed dia...
