Typical Antbirds (Thamnophilidae)

Black-throated Antbird (Myrmeciza atrothorax) - HBW 8, p. 665

French: Alapi de Buffon German: Braunscheitel-Ameisenvogel Spanish: Hormiguero Gorginegro
Other common names: Spot-breasted Antbird (“stictothorax”)

Taxonomy: Formicarius attothorax [sic] Boddaert, 1783, Cayenne, French Guiana.
Genus appears not to represent a monophyletic grouping, but traditional arrangement maintained pending further phylogenetic study. Affinities uncertain; possibly not closely related to other members of genus. Taxon named as stictothorax (lower R Tapajós, in Brazil) considered a separate species by some authors and a race of present species by others, but recordings and specimens obtained near type locality suggest that it is a plumage variant of race melanura. Further, described races obscurata (E Peru, W Brazil) and griseiventris (W Bolivia) considered inseparabl.. View all taxonomy...

Taxonomy: Formicarius attothorax [sic] Boddaert, 1783, Cayenne, French Guiana.
Genus appears not to represent a monophyletic grouping, but traditional arrangement maintained pending further phylogenetic study. Affinities uncertain; possibly not closely related to other members of genus. Taxon named as stictothorax (lower R Tapajós, in Brazil) considered a separate species by some authors and a race of present species by others, but recordings and specimens obtained near type locality suggest that it is a plumage variant of race melanura. Further, described races obscurata (E Peru, W Brazil) and griseiventris (W Bolivia) considered inseparable from latter, which itself highly variable; re-examination of populations S of R Amazon, employing other data (e.g. genetic) in addition to morphological studies, is required. Five subspecies recognized.
