Elusa ustula Hampson

Elusa ustula Hampson, 1909, Ann. Mag. nat. Hist. (8), 4:375.

Diagnosis

This is the smallest Bornean species. The male antennae are typically nodular. The forewings are deep, rich brown, only weakly marked. The male eighth sternite is only weakly corematous as in the previous two species. The uncus is hammer-headed, the valves rather tapering and with fine setae over most of the surface; the harpe is strong, simple, curved, and there is no corema. The aedeagus has an oblique row of short spines near the apex and a mass of coarse spines at the distal end of the vesica.
