Lacida Walker

Type species: antica Walker, Sri Lanka.

Synonyms: Antipha Walker (type species costalis Walker, Sri Lanka); Utidava Walker (type species incomptaria Walker, Sri Lanka).

The genus currently contains two species (the generic types) from the Indian Subregion, but a few Sundanian species are similar to these in facies and male genitalia characters. The moths are grey with deep, rather rounded forewings with angled fasciae and black marginal spots, irregular in size.

The male abdomen has tymbals. In the genitalia, the uncus is long, slender and the saccus moderate. The tegumen is relatively broad, with well developed bands of thickening. The valves are diagnostic, very shallow centrally, but with acute processes well separated from each other dorsally and ventrally, the ventral ones very small in the generic type species. The aedeagus vesica has a single distal cornutus.

The female (antica) has dense scale tufts on the expanded intersegmental area. Segment 8 and the ovipositor lobes are rather compressed together, but the ductus is broadly funnel-like and setose.

Moore (1883) illustrated and described the larva of the type species. It is blackish brown, thicker centrally, and with short setae on the verrucae. There is a transverse pale pink line between segments A2 and A3.

As well as the Bornean species below, Schintlmeister (1994) illustrated two further species that are congeneric: L. vertiginosa van Eecke comb. n. (Sumatra, Java) and L. morawae van Eecke comb. n. (Sumatra).
