Brunia Moore Gen. rev.

Type species: antica Walker, Sri Lanka.

This genus is revived from synonymy with Eilema and defined on male genitalic characters, though a number of the species have a small areole in the forewing venation, and most have sexual dimorphism of forewing facies. The uncus is relatively short, with a dorsal ridge and is slightly expanded at the base as in Eilema, but the saccus is much shorter, narrow, rather acute and has no membrane with hairs or coremata. The valve tapers distally to a rounded apex that is downturned; the saccular process is always shorter but usually robust, and the ventral margin of the sacculus is often angled. The aedeagus apex is usually extensively spined, the spines short, broad, directed apically. The vesica has several broad diverticula that can be scobinate or bear robust cornuti, one of which at least is usually very shallow and asymmetric.

The females usually have the bursa elongate, the basal half sclerotised and having a small basal appendix, and the distal half containing two small scobinate signa.

Apart from the type species and those transferred below, the genus also includes B. cucullata Moore comb. n. (Andamans), B. dorsalis Walker comb. n. (Sula Is., New Guinea, N. Australia), B. ekeikei Bethune-Baker comb. n. (New Guinea) and B. testacea Rothschild comb. n. (Solomons). Australasian taxa may be numerous and in need of revision.

The first two species discussed below were placed in synonymy (e.g. Hampson, 1900) with the African taxon vicaria Walker. The male and female genitalia of vicaria have the generic features just described, and there is sexual dimorphism similar to that in sarawaca Butler and apicalis Walker, the male having a darker border to the forewing. The African species is distinguished by a robust bifid saccular process in the male genitalia, but should also be assigned to Brunia, comb. n.
