Eugoa obliquipuncta sp.
8-9mm. The facies is similar
to that of basipuncta, with the dark antemedials and postmedials both
diffusing away paler distally from a sharp edge on their basal side, but both
are distinctly oblique. The hindwings are grey. The male antennae are
bipectinate rather than serrate or ciliate. The male genitalia have the tegumen
shouldered, the uncus angled, and there is a hirsute process from the valve
sacculus that is larger than the part of the valve distal to its point of
origin. The aedeagus has a subapical cluster of small spines. The female
genitalia are similar to those of basipuncta, but the ostium is flanked
by a pair of thumb-like processes.
