Chamaita Walker

Type species: trichopteroides Walker, Borneo.

Synonym: Homopsyche Butler (type species nudarioides Butler, Bismarck Is.).

This genus has a similar maculate, translucent appearance to Schistophleps, but is distinguished by an elongate, hairy scape to the male antenna. The forewing venation is different, lacking veinlets in the costal area and having the veins arising from the cell reduced, with only one dichotomous branching system in the radial sector (Fig 5e); females usually have two (one in the type species, however) veins anterior to this, but males may have only one, often accompanied by narrowing of the cell or a well scaled fold within it. R1 does not anastomose with Sc. The markings are rufous brown, diffuse, rather punctate: an angled antemedial row of spots, a very sinuous postmedial one, and a more evenly curved submarginal one. The markings are strongest on the veins, and there may be more striate marginal markings also.

The male genitalia are diverse in structure, but frequently involve bilateral asymmetry. The females are similarly diverse, with spining in the bursa absent or present in diversity of form.

The genus occurs throughout the Indo-Australian tropics. A further species that may prove to occur in Borneo is C. psocidula van Eecke (Sumatra, Peninsular Malaysia), marked greyish in a similar manner to Caulocera crassicornis Walker (see Caulocera crassicornis Walker) but with typical Chamaita antennae. This may be a synonym of C. nubifera Hampson (Philippines).

An undescribed species from Peninsular Malaysia was reared from a pupa in a loosely spun cocoon incorporating larval hairs, it was found on the skin of an orange. The genitalia of a male from the same locality (slide 5124) show similar asymmetry to those of C. nudarioides Butler stat. rev. (slide 5133).
