Black-throated Thistletail (Asthenes harterti)


French: Synallaxe à gorge noire German: Schwarzkehlcanastero Spanish: Piscuiz gorjinegro

Schizoeaca harterti


, 1901,

Unduavi (Hichuloma), La Paz, Bolivia


This species and A. coryi, A. perijana, A. fuliginosa, A. griseomurina, A. helleri, A. palpebralis and A. vilcabambae (with ayacuchensis) were previously separated in genus Schizoeaca, and sometimes considered conspecific, although plumage patterns differ to an extent not found within species-level taxa in Furnariidae; genetic data#R#R reveal that all of these taxa, rather than forming a monophyletic group, are nested within Asthenes. Two subspecies recognized.
