Lybius leucocephalus usukumae Neumann, 1908: 46 .

Now: Lybius leucocephalus lynesi C.H.B. Grant & Mackworth-Praed, 1938 . See del Hoyo & Collar (2014); but see also Peters (1948: 58); Short & Horne (2002).

Holotype: ZMB 50.29 (Fischer no. 189), skin, male, collected at “Kagehi”, [06.12.1885].

Paratype: ZMB 29077 (Emin Pasha no. 687), skin, male, collected by Emin Pasha at “Bussissi”, [16.10.1890] .

Type locality: “ countries on the south and south-east shore of Lake Victoria”, from the original description and “Kagehi” [ Kayenzi , Mwanza Region, Tanzania], the locality of the holotype .

Remarks: In the original description the holotype was mentioned as the “type” and the collecting date is provided. ZMB 29077 collected by Emin Pasha was designated as a paratype by Neumann, who compared it with all specimens available at the ZMB, and its locality is included in the type locality. Neumann (1908) considered the type locality as “countries on the south and south-east shore of Lake Victoria”. Simultaneously, he defined “Kagehi” [Kayenzi, Mwanza Region, Tanzania] as type locality with the designation of a holotype. The form usukumae was regarded as a synonym of Lybius leucocephalus albicauda (Shelley) ( White 1965: 254) , but Short & Horne (2002) considered it an intergrade between albicauda and lynesi (see Dickinson & Remsen 2013: footnote p. 330).
