Comments. The male of Labomimus bannaus can be readily recognized by a large disc-like process at the apex of antennomere 9, basally expanded antennomere 10, curved antennomere 11, as well as by the unique form of aedeagus. This species was originally described from Xishuangbanna, Yunnan, southern China, and is here newly recorded from Vietnam and Laos. There is no obvious morphological difference between the population from China and those from Laos and Vietnam.

Distribution. China: Yunnan; Vietnam: Ninh Bình, Đồng Nai; Laos: Bolikhamsai, Ehammouan, Champasak, Attapeu (Y I N et al. 2013a; this paper). First country records for Laos and Vietnam.
