Aedeagus sclerotized with dorsoatrium slightly arched in lateral view; aedeagal shaft long, straight, tapering apically and sword-like in ventral view, slightly arched in lateral view ( Figs 47, 48 ).

Examined type materials. Holotype: Male, CHINA, Yunnan Province, Menglun , 101.28°E, 21.92°N, 10 June 1982, coll. Jingruo Zhou and Sumei Wang. Paratypes: 1 Female, same data as holotype . 2 Males, Yunnan Province, Xishuangbanna , 100.91°E, 22.01°N, 8 July 2017, coll. Weijian Huang.
