Nirmides Hering

Type species: basalis Walker
This genus embraces small species with triangular forewings that are apically more acute than in most other genera. The basic pattern of the forewing consists of a basal zone, usually pale, bounded distad by a straight border running from one third along the costa to just subtornally on the dorsum. The discal zone is marked by a transverse dash beyond which is a irregular pale submarginal.

The antennae are broadly bipectinate over the basal half in the male. The palps are upcurved. The venation is as in Fig. 37.

Nirmides basalis

The male genitalia are diagnostic,: the eighth sternite is distally bifid, sclerotised; the saccus is well developed; the uncus is almost completely divided, the gnathus horizontally flattened, broad; the valves are vestigial, reduced to small setose ampullae, but there are prominent socii from the tegumen.

The female genitalia have a relatively short ductus bursae, the bursa unornamented, and the eighth segment unmodified.

The genus consists of the type species and three other Bornean species described below. In the Philippines there occurs the pale orange N. pura West comb. n. N. cuprea Moore from the Himalaya has not been examined but the illustration in Hering (1931) indicates it is larger than the other species, possibly not related (see next genus also).
