Nothomiza Warren

Type species: costalis Moore, India

Synonym: Organomiza Wehrli (type species formosa Butler, Japan).

The majority of species in this Oriental genus have wings where yellow ground colour is extensively suffused with pinkish grey such as to leave only marginal fragments of pure ground colour exposed, particularly triangles on the forewing costa. The condition of the male antennae ranges from bipectinate (e.g. costalis) to ciliate (e.g. xanthocolona Meyrick).

The male genitalia are typical of the group with peg-like setae on the valves, and usually have some modification to the valve costal margin. Socii are present, and flanked by massive flanges from the tegumen in the type species and lesser ones in other species.

The aedeagus vesica usually bears one or more cornuti. In N. formosa and N. flavicosta Prout (Taiwan) there is an unusual longitudinally carinate plate between the seventh and eighth abdominal segments.

The female genitalia (costalis, xanthocolona) have the bursa elongate, pyriform, more or less generally sclerotised but not fluted, its inner walls bearing a profuse scattering of spines of varying sizes, often large, but no distinct signum.

N. formosa has been reared from several species of Ilex (Aquifoliaceae) in Japan (Sato & Nakajima, 1975). The ashy grey larva with paler flanks and dark spiracles has been illustrated by Sugi (1987).

There is a single species in Borneo, two in Sumatra and none further east.
