Omiza Walker Gen. rev.
Type species: pachiaria Walker, Indian Subregion, Andamans (affinis
Moore), Cochin. This genus is revived to contain a number of large species

narrow with an oblique, often concave postmedial that is colinear with a similar
fascia on the hindwing.

pleated, ventral part. The gnathus is apically scobinate. The furca has the left

but more irregular. The base of the bursa has a zone of sclerotised
The genus is mainly Oriental, consisting of the type species and those
