Description. MALE. Body length 5.3−5.4 mm, wing length 5.0− 5.1 mm.

Head ( Figs 25−26 ) yellow. Frons as long as wide and parallel–sided, a pair of pale brown stripes extending to ocellar triangle; ocellar setae incomplete. Parafacial with a row of short setulae on apical half of inner margin. gena about 1/8 height of eye. Antenna yellow; 1st flagellomere pale yellow, about 1.4 times longer than high; arista brown except for yellowish base, with longest ray slightly shorter than 1/2 height of 1st flagellomere. Proboscis and palpus yellow.

Thorax ( Fig. 27 ) yellow. Mesonotum with 0+3 dorsocentral setae (anterior dorsocentral setae behind the transversal suture), acrostichal setulae in irregular 6 rows. Legs mostly yellow, all tarsomeres 3−5 brown. Fore femur with 5 posterodorsal setae, 4 posteroventral setae and ctenidium with 12 short setae; fore tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Mid femur with 4 anterior setae and 1 short apicoposterior seta; mid tibia with 1 strong preapical anterodorsal seta and 3 strong apicoventral setae. Hind femur with 1 preapical anterodorsal seta; hind tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Wing ( Fig. 29 ) pale yellow, brown apical spots on R 2+3, R 4+5 and M 1 slightly separated; brown cloud on dm-cu; a brown rectangular median spot on R 4+5 far from brown cloud on crossvein dm-cu; subcostal cell dark brown at apex; 2nd (between R 1 and R 2+3), 3rd (between R 2+3 and R 4+5) and 4th (between R 4+5 and M 1) sections in proportion of 2:1:1.1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.5; ultimate section of CuA 1 about 1/8 of penultimate. Halter yellow.

Abdomen ( Fig. 28 ) yellow, male tergites 3−6 each with brown posterior margin. Male genitalia ( Figs 30−34 ): Syntergosternite 7+8 circular; epandrium broad and slightly swollen subapically in lateral view; surstylus with a small triangluar process with several setulae in lateral view; hypandrium H-shaped and hypandrial apodeme short; pregonite shorter than postgonite, both of them sharp at apex; phallus with a pair of sharp teeth-like processes at middle in ventral view and small sharp dorsal processes subapically in lateral view; phallapodeme longer than phallus.

FEMALE. Unknown.

Type material. Holotype ♂ ( IMAU), CHINA, Shanxi Province, Foping County, Daguping, 1329.2 m, 24. VIII. 2014, Xiumei Lu . Paratype ( IMAU): 1♂, data same as holotype .

Distribution. China (Shaanxi).

Remarks. The new species is similar to Homoneura (Homoneura) acutata Yang, Zhu & Hu, 1999 from China (Henan), but the latter has the following features: the mesonotum having acrostichal setulae in 10 rows and the surstylus having sharp apex pointing downwards, and the phallus lacking pairs of teeth-like processes.

Etymology. The new species is named after the collecting locality Daguping.
