Daddala Walker

Type species: quadrisignata Walker, [India].

Elpia Walker (type species achaeoides Walker, Sulawesi).

The wing margins are more dentate than in the preceding genera, particularly that of the hindwing where there may be a longer process on M3, especially in
D. brevicauda Wileman & South, though this is not as conspicuous as in the next genus. The forewing pattern often involves a transverse component through or adjacent to the reniform that can separate a darker basal area from a paler one distally, though this may be obscure in some forms of the more variable species. The underside has prominent but narrow dark fasciae that show similarity in the splayed disposition of those of the forewing to those in the next genus (as does the lobe to the hindwing dorsum of D. quadrisignata Walker). However, though the male antennae are fasciculate or bipectinate, those of the females are filiform.

In the male abdomen, the eighth tergite is shortened to a narrow transverse strip apart from narrow, semi-detached lateral processes that flank the sternite. The latter is massively enlarged, square, with a crescent-shaped, framed lacuna anteriorly that bears hair-setae. This does not appear to be homologous with the typical framed corematous condition. The edges of both sternite and tergite are invested with fringes of hairs. The genitalia are characterised by long, narrow valves that become slightly but sharply upturned at their central point; there is a central, tongue-like flap subbasally.

The female genitalia are typical of the
Sypna group (see p. 171).

The genus is exclusively Indo-Australian, extending from the Indian Subregion to New Guinea.
