African Dusky Flycatcher (Muscicapa adusta) - HBW 11, p. 122

French: Gobemouche sombre German: Dunkelschnäpper Spanish: Papamoscas Sombrío
Other common names: Dusky Alseonax/Flycatcher

Taxonomy: Butalis adusta Boie, 1828, “Auteniquoi” = George, Western Cape, South Africa.
Race poensis was formerly referred to sometimes as obscura, but latter name is preoccupied. Exhibits considerable clinal and intrapopulation variability (also variation in appearance of skins arising from different taxidermal procedures). Up to 20 races have been recognized, but many of these considered unwarranted: thus, albiventris (highlands of W Cameroon), kumboensis (montane forest of SW Cameroon) and okuensis (montane forest of Mt Oku, in W Cameroon) treated as synonyms of poensis; grotei (N Cameroon and NW Central African Republic), s..

Ten subspecies currently recognized.
