Triorbis HampsonGen. rev.
Genus Details
Type species: annulata Swinhoe, Burma.
The forewings of the two included species are rich brown that is bisected basally by a golden streak. The male antennae are rather lamellate, robust.
The male genitalia have the uncus reduced or absent. The valves are also reduced (aureovitta Hampson) or with a long, curved process from the base of the costa (annulata). The vinculum is variably developed into a flimsy, slightly corematous, pocket-like structure. The aedeagus has a convolute vesica with some areas of scobination and sclerotisation.
In the female, the bursa is large, with a strong, but relatively short signum consisting of the pair of spined bands or triangles (annulata) typical of the subfamily; the spining is robust.
The two included species are described below.
