Arasada Moore

Type species: pyraliformis Moore.

The male antennae are ciliate, and the hindlegs bear scale tufts over the tibial to tarsal section. The wings are variably buff to grey-brown, with irregular and diffuse paler fasciation and with an irregularly punctate, blackish submarginal. The hindwing postmedial, however, is typically white, often somewhat broken, and straight with minor irregularities. The forewing discal mark is typically a white dot, but that of the hindwing is bipunctate, blackish. The hindwing dorsal margin of the male can have a fringe of straw-coloured hair-scales similar to those of the hindleg.

The male abdomen has the eighth segment unmodified. The uncus is short, broad, apically acute and downturned. The tegumen is narrow, and there is a long, narrow saccus. The valves are narrow with distal processes much as in the next genus: a narrow unsclerotised and setose apical process and a more heavily sclerotised pair of processes that are developed from the costa and sacculus. The valve bases are fused to the juxta; this is long, slender and distally bifid. The aedeagus is moderate, straight, having a short vesica with a number of small diverticula and sometimes a small sclerite at its centre.

The female genitalia have the ostium set in a broad, deep, scobinate pouch formed from the eighth segment within the seventh, and this may contain more complex structures such as ridges or spines. The ductus bursae is short; the corpus bursae is elongate, somewhat pyriform, usually with a central ring of spines, but shows no significant coiling at its base.
