Borbo detecta Trimen 1893

Borbo detecta (Trimen)
Pamphila detecta Trimen, 1893: 141; pi. 8, fig. 12 (Natal). =Pamphila fallatus Holland, 1896: 63 (Mabille ms. name). = Pamphila pyrrhobaphes Mabille, 1897: 214 (Tanganyika). = Baoris auritinctus Butler, 1898: 416 (Kenya).
The range of this species given by Evans (1937: 182 — primarily South and East African records) is puzzling since the bulk of material in Carnegie Museum is from Cameroon, Gabon and the Congo, a distribution which validates Holland's (1896: 63) records from the first country. Unless Evans' (1937: 178-179) key to the species is in error in the separation of this species and the last, detecta has a far greater range than he ascribes to it. The male genitalia of Cameroon specimens are more like his figure (1937: pi. 29) of the present species than of perobscura, but, as is so often true of his figures, there are just enough discrepancies between the specimens and the plates to cause us to wonder.
The first Liberian record: Harbel, 1 2 , I, 1 2 , X (Fox).

Borbo detecta, the rusty swift, is a butterfly of the family Hesperiidae. It is found from South Africa to eastern Africa and Zaire. In South Africa it is found in Eswatini and lowland riverine forests and savannah in KwaZulu-Natal to south-eastern Mpumalanga. The habitat consists of moist woodland.

The wingspan is 34–36 mm for males and 36–38 mm for females. Adults are on wing year-round, but are scarcer in winter in southern Africa.

The larvae feed on various Poaceae species, including Ehrharta erecta.
