Femur with a ventroapical black spot and tibia with a black basal ring. Wing with preapical spot on R2+3 confluent with a brown spot on R4+5 and brown cloud on dm-cu, basal part of R4+5 brown, basal 2/3 of CuA1 brown; an elliptic subbasal spot on R2+3 confluent with brown cloud on r-m; a brown apical spot on Sc and R1, confluent with subbasal spot on R2+3 and broad brown cloud on r-m. Male tergites 2–6 (female 2–7) with black posterior margin.
Description. MALE. Body length 3.7 mm, wing length 4.0 mm. FEMALE. Body length 4.1–4.3 mm, wing length 4.1–4.5 mm.
Head brownish yellow. Frons as long as wide and parallel-sided, with two brownish black stripes extending to ocellar triangle; ocellar triangle black; oc longer than anterior or, anterior or longer than 1/2 length of posterior or. Face yellowish brown, with a thin brown transverse stripe on ventral margin, parafacial yellowish brown with black inner margin; gena yellow, about 1/5 height of eye. Antenna brownish yellow, 1st flagellomere blackish brown except for yellow on basal 1/3, 1.4 times longer than high; arista black except for brownish base, ray short plumose, with longest ray as long as 1/2 height of 1st flagellomere. A blackish brown triangle spot present between base of antenna and eye. Proboscis and palpus brown.
Thorax yellow with grayish white pruinosity. Mesonotum with a wide grayish black medial stripe and two brown lateral stripes; 0+3 dc (1st post-sutural dc behind transverse suture), acr in 8 rows and prsc shorter than 1st post-sutural dc. Scutellum blackish brown except for yellow lateral margins, with grayish white pruinosity. Legs dark yellow except for femora blackish brown; femur with a ventroapical black spot and tibia with a black basal ring. Fore femur with 6 pv, 8 pd, and ctenidium with 13–14 short setae; fore tibia with 1 long preapical ad and 1 short apv. Mid femur with 6 a and 1 app; mid tibia with 1 strong preapical ad and 2 strong apv. Hind femur with 1 weak preapical ad; hind tibia with 1 strong preapical ad and 1 short apv. Wing (Fig. 18) pale yellow with preapical spot on R2+3 confluent with a brown spot on R4+5 and brown cloud on dm-cu, apical spots on R4+5 and M1 confluent; basal part of R4+5 and basal 2/3 of CuA1 brown; an elliptic subbasal spot on R2+3 confluent with brown cloud on r-m and brown apical spot on Sc and R1; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1) sections in proportion of 4:1.4:1; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.2; ultimate section of CuA1 about 1/5 of penultimate. Halter pale yellow.
Abdomen dark yellow with grayish white pruinosity, male tergites 2–6 (female 2–7) with black posterior margin. Male genitalia (Figs 244–248): syntergosternite semicircular with three setulae around spiracle; epandrium broad, round apically in lateral view; surstylus with a small claviform inner process in lateral view; hypandrium nearly H-shaped with a triangle middle ventral segment; postgonite longer than aedeagus, coniform and curved forward in lateral view; aedeagus round apically with a pair of acute dorsal processes in lateral view; aedeagal apodeme shorter than aedeagus.
Type material. Holotype ♂ (CAUC), CHINA, Zhejiang Province: Shunxi, Hengyuan, 22. VII. 2007, Yajun Zhu. Paratypes: 2 ♀ (CAUC), CHINA, data same as holotype.
Distribution. China (Zhejiang).
Remarks. The new species is very similar to Homoneura (Homoneura) chishuiensis Gao & Yang from China (Guizhou, Hainan) in the following characters: mesonotum with a wide grayish black medial stripe and two brown lateral stripes; wing with large brown clouds; abdominal male tergites 2–6 (female 2–7) with black posterior margin, syntergosternite semicircular with setulae around spiracle and surstylus with a small claviform inner process in lateral view, but it can be separated the latter by the following characters: the brown cloud being on r-m with an acute tip; the hypandrial apodemes being far from each other; the aedeagus being round apically; the aedeagal apodeme shorter than the aedeagus. In chishuiensis, the brown cloud on r-m is round without the acute tip; the hypandrial apodemes are close to each other; the aedeagus is subuliform apically; the aedeagal apodeme is longer than the aedeagus. (Gao & Yang 2006).
Etymology. The species is named after the type locality Shunxi.
