Gasterocome Warren

Type species: pannosaria Moore.

In facies this genus resembles Alcis, particularly some of the Bornean species, but is distinguished by translucence, particularly on the hindwing where there is a distinct dark brown border with a straight interior edge. The forewing discal spot is pale-centred.

The male antennae are ciliate (bipectinate in Alcis). The fovea is absent (present in Alcis). A setal comb is present on the third sternite. The male genitalia have a number of unusual features: the uncus is narrower over the apical part, which is square-ended; the gnathus is broadly triangular with a central longitudinal row of oblong plates (a similar feature is seen in Coremecis Gen. n.); the valve has the apex expanded, the cucullus zone membranous, crinkled, with a fold extending basad to an angled subcostal process; a band of short setae occurs centrally alongside this angled process; there is a slender, curved, digitate process from the sacculus; the aedeagus is slender, with a small, laterally directed spine at the apex.

In the female genitalia the basal part of the bursa continues on from a sclerotised ring in the short ductus as a long slender scobinate tube that expands out into a rather narrow, pyriform distal part. The signum, at one third in the pyriform section, consists of two separate bosses adjacent to each other, each with a small spine.

The genus contains a small number of Oriental species, mainly allopatrically distributed. As well as the type species there is G. fidoniaria Snellen (Sulawesi, with a related but slightly different taxon in Seram), G. conspicuaria Leech (China; placement needs investigation) and G. polyspathes Prout (Sri Lanka).
