Goniocraspedon Hampson

Type species: mistura Swinhoe, Indian Subregion, Christmas I..

The genus consists of species that have a more variegated, fasciated wing facies than those in the previous genus, Parilyrgis and the next, the wings being slightly shorter and deeper. The fasciation is only weak in the type species, however. The labial palps are directed forwards, the second segment moderate, the third short, more narrow. The male antennae are bipectinate.

In the male abdomen, the eighth segment is of the framed corematous type, the tergite with heavier sclerotisation in a central band and along the anterior margin, like a letter ‘T’. The uncus is slender, moderate in length, and the valves variable in shape. The vinculum is broad, rather angular, slightly produced laterally as well as distally. The aedeagus vesica is smaller than in the other Bornean genera in the group, resembling that in
Parilyrgis.

The female genitalia have a distinct, deciduous tuft of scales associated with the eighth segment. The ostium is also associated with the anterior of this segment with a broad but shallow, slightly corrugated pocket. The ductus is short, narrow, the corpus bursae ovate with extensive coarse scobination.

The genus consists of the type species, those described below, and
G. aroa Bethune-Baker (New Guinea). The last is listed by Poole (1989), but appears not to relate to the type species; it is currently included in the Hypeninae in BMNH. The record of the type species from Australia by Nielsen et al. (1996) needs checking in view of the complexity of species discussed below, as does the subfamily placement of the genus (see under Ilyrgis).
