Hind coxa with many dense ventral spines (female absent); hind femur with 1 preapical anterodorsal seta; hind tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Wing (Fig.) yellow, subcostal cell hyaline; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1+2) sections in proportion of 5.9: 2.4: 1; r-m after middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1: 1.5; ultimate sections of CuA1 about 1/8. Halter pale yellow.

Abdomen yellow. Male abdominal tergite 6 about two times as high as tergite 5 in dorsal view, and sternite 5 bilobate posteriorly with 3 stout teeth on each lobe (Fig. 76). Male genitalia: syntergosternite 7+8 circular; surstylus widen and slightly curved in posterior view; phallus slender with a pair of teech-like processes; phallapodeme short Y-shaped.

Type material. Holotype ♂ (IMAU), CHINA, Gansu Province: Zhangye, Mati Temple, 2620 m, 10. VII. 2011, Sipei Liu. 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. IX. 2016, anonym; 1♂, 1♀ (IMAU), Hulunbuir, Hanma National Natural Reserve, Central management station, 200-meter plank roads along the stream, Malaise trap, 850 m, 28. VIII. 2015., anonym?

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.
