Paratypes: 2♀♀ (IMAU), Zhangye, Forest Park, anonym; CHINA, Nei Mongol: 1♂ ( IMAU), Hulunbuir, Hanma National Natural Reserve, Central management station, 200-meter plank roads along the stream, Malaise trap, 850 m, 26.

Distribution. Nei Mongol (Hulunbuir).

Remarks. The new species is similar to Homoneura ( H.) ozerovi Shatalkin, 1993 from Russia, but the latter has four stout spines on each lobe of male sternite 5. The new species is also similar to Homoneura ( H.) tesquae ( Becker, 1895) from Russia, but the latter has male tergite 6 nearly as high as the sum of the previous three tergites (original description from Becker, 1895 and Czerny, 1 932) and the latter has six stout spines on each lobe of male sternite 5 ( Papp, 1978: fig. 16).

Etymology. The species is named after the collecting locality.
