Hyphaenia tonkinensis (Laboissière, 1936), comb. nov.

Platyxantha tonkinensis Laboissière, 1936: 239 (original description)

Type material examined. HOLOTYPE: ♂, ‘ Hoa-Binh / de Cooman [w, h] // TYPE [red letters, p] / ♂ [w, h] // Platyxantha / tonkinensis / m [h] / V. Laboissière – Dét. [w, p] // Le Moult Vend. / via Reinbek / Eing. Nr. 1, 1957 [w, p]’ (ZMUH).

Comments. REID (1999) transferred this species to Taumacera without any comments. The holotype is deposited in the ZMUH and I studied it many years ago. Based on my notes and photographs taken at that time, I am excluding this species from Taumacera, and I provisionaly classify it as Hyphaenia tonkinensis (comb. nov.).
