Iridoplecta
Warren
Type species: ferrifera Moore.
The facies consists of pinkish brown markings on a whitish ground, the
marking being particularly intense in the marginal zone distal to the postmedial.
Both the forewing (weakly) and the hindwing (more strongly) are angled centrally
at the margin. The male antennae are ciliate and the chaetosemata normal rather
than of the semiothisine type. There is no fovea.
The male genitalia have the valves bifid, with the dorsal and ventral,
slender, apically curved arms separated by a short central lobe. The uncus is
apically rounded and lacks horns. The aedeagus is short with a small cornutus at
the base of a finely scobinate tube that has a lateral lobe bearing two further
large cornuti at its apex.
The female genitalia have the bursa asymmetrically bilobed, the basal
half of the major lobe being sclerotised and fluted, this extending over the
adjacent side of the minor lobe.
The genus contains the type species, I. ochrias West from the
Philippines and I. differens Bastelberger from Taiwan.
