Dusuna bimaculata Cai & Kuoh

Dusuna bimaculata Cai & Kuoh, 1993: 449, pl. 2, figs A–C

Distribution. China (Yunnan).

Remarks. This species was described from the female holotype (not examined) with the following data: “ China, Yunnan, Menglun, 8 April 1974, Chongsheng Wei”. It was distinguished in its original description in the following way: “This species can easily be separated from other species in the genus by the two black markings on the posterior margin of vertex”. However, due to the similarity of congeneric females in Dusana and absence of males in this species it is not possible to be certain of its identity or indeed its validity.
