Type species: cyanopyga Felder (= chloropyga Walker).
Synonym: Spilobotys Butler (type species arctioides Butler,
Species in this genus are bright yellow with orange spots or fasciae on
the forewing. At the base of the forewing and on the thorax occur small black
spots. The abdomen is banded with yellow and blue-black, often with the apex
broadly the latter colour.
The male lacks a retinaculum; the antennae are filiform, with short
cilia. The genitalia are very elongate, the valves simple, narrow, the uncus
slender, tapering to a point. The tegumen is ‘shouldered’ in the type
species but not in all species. There is a large saccus. The aedeagus vesica is
large, bilobed, finely scobinate throughout.
In the female genitalia the distal margin of the eighth tergite is
fringed with setae, and it gives rise to a pair of finger-like invaginations
that run anteriorly. The ductus bursae is long, sclerotised, and the bursa is
also elongate, corrugated throughout, with the ductus seminalis arising basally
The genus is distributed from Sundaland to Queensland, Vanuatu and New
Caledonia. It was reviewed by Holloway (1979).
