“Mataeomera” obesicosta Holloway sp. n.

♂ 6mm. The facies of this species is again much as in the previous three, but the thorax and forewing area basal to the antemedial are a slightly paler grey than the rest of the wings. The genitalia have valves of a similar form to digitata except the basal half of the costa has a more marked bulge, and the cucullus and costal spine are straighter, though still adjacent to each other. The central process is similarly digitate with a subbasal accessory process, but has its greatest flexure immediately distal to that process. The aedeagus is similar but has three flatly obtuse spines near its apex and no barbs. There is a small cornutus in the vesica.
