Earias Hübner

Type species: clorana Linnaeus, Sweden.

Synonyms: Aphusia Walker (type species speiplena Walker = vittella Fabricius, India); Cinciana Strand (type species nubica Strand = insulana Boisduval, Africa); Cincianella Strand (unnecessary replacement name for Cinciana); Digba Walker (type species uninotata Walker = flavida Felder, Borneo).

The adults are small, robust, rather glossy, with yellow or green predominant in the forewing coloration. The hindwings are usually white. The forewing lacks an areole; the radial sector branching system is ((R3, R4) R5). The hindwing veins around the posterior angle of the cell are reduced to three, with the anterior two of these stalked.

The male abdomen lacks tymbal structures, but, in some species (e.g. vittella), there are coremata laterally between the second and third segments. The eighth segment lacks apodemes. The genitalia have a short but distinctly bifid uncus. The valve is broadly bilobed distally, the dorsal lobe bearing an unusual, ventrally directed spine. There is also a small flap near the centre of the valve costa.

The female genitalia are characterised by a strongly fluted, elliptical, scobinate bursa copulatrix set on a long and very narrow ductus bursae. An appendix bursae may be present.

The larva has unusual chaetotaxy for the family as indicated above, and some of the setae can be supported on slender and elongated chalazae, giving a spiny appearance.

The pupa lacks a cremaster but some abdominal segments may have beaded or toothed margins.

Four species occur in Borneo, three very widespread and one Sundanian.
