Platyxantha bicornuta Medvedev, 2001: 185 (original description)

Type material examined. HOLOTYPE (photograph): ♂, ‘2. Vietnam, Prov. Vinh-Phu, / Tamdao , 800-1200 m, forest / 12-22.IV.1986, leg. L. MED- / VEDEV, S. GOLOVATCH et al. [w, p] // HOLOTYPUS [p] / Platyxantha / bicornuta m. [h] / L. Medvedev det. 19 [p] 98 [r, h]’ ( LMRM).

Comments. I examined only photographs of the holotype of Platyxantha bicornuta . Based on the structure of the aedeagus with a bifurcate apex I tentatively transfer it to Hyphaenia , however, further study is necessary to confirm this placement.
