 Diagnosis. Face with a pair of blackish brown elliptical spots (sometimes two spots confluent) extending to inner margin of parafacial. Wing slightly yellow, with a narrow pale brown stripe on dm-cu. Abdominal tergites 1–2 each with a pair of blackish brown lateral bands, tergites 2–6 each with a black median spot, sometimes confluent with blackish brown lateral bands on tergites 3-4, tergites 5–6 each with a pair of blackish brown lateral bands.   
 Description. MALE. Body length 3.9–4.3 mm, wing length 3.7–4.1 mm. FEMALE. Body length 3.7–4.1 mm, wing length 3.8–4.2 mm.   
 Head (Fig. 1) pale yellow. Face with a pair of blackish brown elliptical spots (sometimes spots confluent), extending to inner margin of parafacial. Frons about as long as wide and parallel-sided, with two narrow blackish gray stripes along or rows and a narrow brown triangular median stripe extending to ocellar triangle; ocellar triangle grayish black; oc strong, about as long as anterior or, anterior or slightly shorter than posterior or. Gena about 1/6 height of eye. Occiput with a wide grayish black stripe confluent with ocellar triangle. Antennal scape and pedicel black, 1st flagellomere brownish except yellow basally; 1st flagellomere 1.8 times longer than high; arista long plumose, blackish brown except brownish basally, with longest hairs longer than height of 1st flagellomere. Proboscis yellowish brown, with yellowish and blackish hairs; palpus pale yellow with blackish hairs.   
 Thorax (Fig. 12) blackish brown with grayish white pruinescence. Mesoscutum with white pruinescence on anterior margin, 0+3 dc (anterior dc clearly behind transverse scutal suture), acr in 8 somewhat irregular rows. Anepisternum and katepisternum pale yellow with whitish gray pruinescence, and each with a grayish black spot. Scutellum brownish black except yellow along apical margin, with yellowish gray pruinescence. Legs pale yellow, but all tarsi dark yellow, except tarsomere 5 brown on apical half; hind tibia with an incomplete brown basal ring. Fore femur with 4 strong pv and 5–6 pd, ctenidium with 9–10 short bristles; fore tibia with 1 long preapical ad and 1 short apv. Mid femur with 6 a and 1 apv; mid tibia with 1 strong preapical ad and 3 strong apv. Hind femur with 1 preapical ad; hind tibia with 1 weak preapical ad and 1 short apv. Wing (Fig. 23) slightly yellow, with a narrow pale brown stripe on dm-cu; subcostal cell hyaline; costa with 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 2.3: 0.6: 0.4; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.3: 0.9; ultimate section of CuA 1 about 1/6 of penultimate. Halter pale yellow.   
Abdomen (Fig. 34) yellow with sparse silvery white pruinescence; tergites 1–2 each with a pair of blackish brown lateral bands, tergites 2–6 each with a black median spot, sometimes confluent with blackish brown lateral bands on tergites 3-4, tergites 5–6 each with a pair of blackish brown lateral bands. Male genitalia (Figs. 42–46): protandrium circular, with a long narrow ventral process; epandrium nearly oblong in lateral view, surstylus consisting of a digitiform process and a narrow curved bar-like process; hypandrium with a pair of long narrow ventral processes, hypandrial apodeme distinct; gonopod columniform and slightly curved; aedeagus without apical incision, dorsal sclerites confluent at dorsal view, with a pair of lateral median teeth and a pair of lateral median processes.  
 Type material. Holotype ♂ (CAU), CHINA, Yunnan Province: Baoshan, Baihualing, Wenquan, 29. V. 2007, Xingyue Liu. Paratypes: CHINA, Yunnan Province: 1 ♂, 3 ♀ (CAU), data same as holotype; 4 ♂, 3 ♀ (CAU), Baoshan, Baihualing, Wenquan, 23. V. 2006, Xingyue Liu; 2 ♂, 2 ♀ (CAU), Baoshan, Baihualing, Wenquan, 23. V. 2006, Yajun Zhu; 1 ♀ (CAU), Nujiang, Gongshan, Dimaluo, 19. V. 2007, Xingyue Liu; 1 ♂ (CAU), Nujiang, Gongshan, Bingzhongluo, Wuli, 25. V. 2007, Xingyue Liu.   
 Distribution. China (Yunnan).   
 Remarks. The new species is somewhat similar to Homoneura (Homoneura) latissima Shi & Yang from China (Hainan) in the following characters: wing with a pale brown stripe on dm-cu, abdominal tergite 6 yellow with a small brown median spot; protandrium circular, with a long narrow ventral process; surstylus consisting of digitiform process and a narrow curved bar-like process; gonopod columniform. But it can be separated from the latter by the following features: face with a pair of blackish brown elliptical median spots (sometimes two spots confluent); antennal scape and pedicel black, 1st flagellomere brownish except yellow basally; aedeagus without apical incision and apical processes. In H. (H.) latissima, the face has no spots; the antenna is blackish brown except the 1st flagellomere is pale yellow apically; the aedeagus has a small apical incision and two pairs of contorted apical processes (Shi & Yang 2009).   
 Etymology. The new species is named after the type locality Baihualing.
