Pogonopygia Warren

Type species: nigralbata Warren.

Both this and the next genus contain species with an Abraxas-like facies: white wings with dark grey spots and fasciae, and an orange thorax, also with black spots. The abdomen is orange or white with black spots. Both contain a few Oriental species.

The male antennae are ciliate. The type species has an irregularly defined foveate zone that extends from the anterior cubital vein to posterior to the anal vein. This is lacking in the only other species in the genus, here transferred from Dilophodes Warren, but present in typical Dilophodes.

The best distinction between the genera lies in the abdominal characters. A setal comb is present in males of both genera; the type species of Pogonopygia has lateral coremata between segments 7 and 8 on the basal margin of 8, and there are hair tufts ventrally on the distal margin of 7 and laterally on segment 3.

P. nigralbata and P. xanthura Prout comb. n. share the following male genitalic features presumed to be apomorphic: a square apex to the uncus (acute in Dilophodes); a tuft of hair-like setae from the valve costa; a prominent terminal harpe to the valve sacculus. P. xanthura resembles Dilophodes in having a clump of deciduous spicules on the aedeagus vesica; in P. nigralbata these are lacking, but there is general scobination. Dilophodes has an acutely triangular apex to the gnathus and is distinguished by dorsal projection of the tegumen as two prominent lobes bearing long, scale-like setae.

In the female genitalia all species have the bursa sclerotised basally, but in Pogonopygia it is elongate, slightly twisted, with a squarish, dentate, mushroom-type signum distally. In Dilophodes the signum is central and consists of a much smaller, more finely scobinate patch that is pinched up centrally. The larva of the type species is described below.
