Derisemias taiwanus Frieser, 1981

Figs. 3 & 8

Comments. This species is distinguished by the head without whitish line and patch, the median line of the pronotum from occiput to beyond the transverse line and elytra uniformly covered with yellowish hairs ( Frieser 1981; Frieser 1989). This species was collected in Taiwan (Fenchihu) and described as an allied species to D. ornatus Jordan, 1928 from Vietnam, without illustration. The holotype was originally deposited in Robert Frieser’s private collection, and later transferred to ZSM. The dorsal and lateral views of the holotype were taken by D. A. Balke, a curator of ZSM, and here are figured out for the first time.
