Gonodontis Hübner

Type species: delia Cramer.

Synonym: Orsonoba Walker (type species rajaca Walker).

This genus is best defined on features of the male genitalia. The sclerotised part of the uncus is slender, but based in a semicircular, membraneous structure. The tegumen is very deep with strong, lateral, digitate processes, usually bifid. The valve is simple, somewhat elliptical. The aedeagus apex is coarsely spined, the vesica globular with a group of short peg-like cornuti set relatively distally. The bursa of the female is an asymmetric hammer-head shape. The male antennae are bipectinate.

As currently constituted, the genus is most diverse in Australia (Queensland): G. diplodonta Turner, G. euctista Turner, G. stramentica Turner, G. zapluta Turner (none represented in London). The two species described below, and the N.E. Himalayan G. aethodrypta Prout, represent it in the Oriental Region, with another, undescribed, species in the mountains of Sulawesi (slide 12357). Taxa from the south-west Pacific (Robinson, 1975; Holloway, 1979) attributed to clelia are probably distinct species. The genitalia of the New Caledonian Gonodontis resemble those of a Queensland specimen (slide 13099) in the strong spining of the aedeagus apex (as in clelia), the lack of cornuti in the vesica (a unique feature), and small tegumen processes that are triangular rather than bifid; they differ in facies, with the New Caledonian species resembling G. pallida Butler and the Australian specimen a medium grey colour.

The biology of the type species is described below.
