Tamba bartelsi Kobes

Tamba bartelsi Kobes, 1997, Heterocera Sumatrana, 12: 56.

Diagnosis

See the previous two species. This is most similar to sobana in facies but with a larger reniform and a more irregular postmedial to the forewing. The portion of the latter anterior to the angle is edged by a series of dark brown spots distally, and this dark brown shade recurs over the submarginal just exterior to these spots, extending to the margin centrally. The male genitalia have the costal process to the valve very large, paddle-like, with an acute angle on the distal side of the handle of the paddle.

Geographical range

Sumatra, Borneo, Thailand (VK).
