Acraea diogenes

Acraea diogenes is a butterfly in the family Nymphalidae. It is found in the Democratic Republic of the Congo (from the south to Haut-Lomani and Lualaba), Angola and north-western and north-eastern Zambia.

Description
A. diogenes Suff. (55 f) is only known in the female, but suggests a thinly scaled form of the preceding species [ Acraea leucopyga ]. Forewing transparent whitish grey, at the apex and distal margin broadly darkened, with discal dots in 1 b and 2 and occasionally also with a median dot, but with no other dots. Hindwing somewhat more fully scaled, above dull grey, beneath with reddish spots; marginal band and black dots almost as in leucopyga. Southern Congo.

Taxonomy
It is a member of the Acraea cepheus species group. But see also Pierre & Bernaud, 2014.
