Fig. 4

Indonemoura geminus Zwick, 1977: 104 ; Murányi & Li, 2013: 173.

Examined material. 1 male ( CAU), Xizang, Chayu County, Shuidianzhan , 2394 m, 2019.VI.13, light trap, 28.6669° N, 97.4750° E, leg. Qicheng Yang.

Remarks. Tergum IX, epiproct, and paraproct characteristics ( Figs. 4a–c ) match well with the description of the holotype male, indicating that the specimen examined above belongs to I. geminus and not its close relative I. shergaoni ( Aubert 1967) as discussed by Zwick (1977). Males of I. geminus are characterized by tergum IX with a symmetrical posterior margin ( Fig. 4a ). The epiproct has stout, curved flagellum ( Fig. 4b ). The outer lobe of the paraproct is L-shaped with an enlarged rounded apex ( Fig. 4c ). This species was previously known from Bhutan ( Murányi & Li, 2013); this record is new for China.
