Xanthodisca vibius Hewitson 1878

[Xanthodisca vibius (Hewitson)]
Astictopteras vibius Hewitson, 1878: 343 (Gabon).
This species is included as a possible Liberian resident since Berger (1962: 453) reports a male from Mount Tonkoui, Ivory Coast, at 1300 meters elevation. This is as strange a record for vibius as is the Holland type of Osmodes staudingeri for rega, and it lends further credence to the hypothesis that rega and vibius are very closely related to, but distinct from, one another.

Xanthodisca vibius, the Vibius orange and Vibius skipper, is a butterfly in the family Hesperiidae. It is found in Cameroon, Equatorial Guinea, Gabon, the Democratic Republic of the Congo, Uganda, western Kenya, eastern Tanzania, Malawi, north-western and north-eastern Zambia and Zimbabwe. The habitat consists of forests and moist dense woodland, especially Brachystegia woodland.

Adults are known to mud-puddle. They are on wing from January to May.

The larvae feed on Aframomum species.
