Glauconycteris machadoi Hayman 1963

Glauconycteris machadoi Hayman 1963 , Comp. Diamantes de Angola, Ser. Cult., 1963: 107.

Type Locality: Angola, Lac Calundo.

Vernacular Names: Machado's Butterfly Bat.

Distribution: Angola; known only from the type locality.

Conservation: IUCN 2003 – Not evaluated; not considered in IUCN / SSC Action Plan (2001).

Discussion: Known only from the holotype. Koopman (1971a:6) treated machadoi as a subspecies of variegata, suggesting that it might be "simply a melanistic mutant individual" of the latter widespread species, which is typically pale creamy buff with a whitish head and pale wing membranes. Alternatively, Hayman and Hill (1971) treated machadoi as a separate species in recognition of its distinct coloration, which includes brown dorsal fur, a dark brown head, dark wing membranes, and a creamy-white underbelly. Peterson and Smith (1973) and Crawford-Cabral (1989c) also treated machadoi as distinct. I follow the latter authors pending additional evidence.
