Thosea trifurca Holloway sp. n.
♂ 17mm.
Externally this species resembles borneensis but with the forewing basal to the medial zone suffused with dark grey. The male genitalia have the gnathus trifid, the central prong perhaps three times as large as the two lateral ones. The uncus is broad, distinctively shouldered. The furca arms are much shorter than the valves, curved. The valves have the costa produced into a strong, slightly curved spine.
