Homoneura (Homoneura) miaoae sp. nov.

( Figs 57−62 , 63−67 )

Description. MALE. Body length 5.6–5.7 mm, wing length 5.3–5.4 mm.

Head ( Figs 58−59 ) yellow. Ocellar setae, anterior and posterior fronto-orbital setae broken. Parafacial yellow, with a row of black short setulae on apical half of inner margin. Gena about 1/7 height of eye. Antenna yellow, 1st flagellomere about 2.5 times longer than high; arista brown except for yellowish base, with longest ray as long as 2/3 height of 1st flagellomere. Proboscis and palpus yellow.

Thorax ( Fig. 60 ) yellow. Mesonotum with 0+3 dorsocentral setae (1st post–sutural dorsocentral setae close to the transversal suture), acrostichal setulae in irregular 6–8 rows. Legs mostly yellow, all femora yellow (sometimes apicodorsal side of fore femur pale brown) and all tarsomeres 3–5 brown at apex. Fore femur with 5 posterodorsal setae, 4 posteroventral setae and ctenidium with 14–16 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 2 strong apicoventral setae. Hind femur with 1 short preapical anterodorsal seta; hind tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Wing ( Fig. 62 ) pale yellow, brown elliptical spot on R 2+3 larger than apical and median spots on R 4+5, and a brown apical spot on M 1+2 (absent on right wing of paratype); a brown stripe on crossvein dm-cu; subcostal cell pale yellow; 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 5.6:1.4:1; r-m beforediscal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.4; ultimate sections of CuA 1 about 1/7. Halter pale yellow.

Abdomen ( Fig. 61 ) yellow. Male genitalia ( Figs 63−67 ): syntergosternite 7+8 close to circular, but sternal part flat; epandrium with two pairs of long dorsal setae; surstylus blunt round and slightly rolled up with several setulae in lateral view; hypandrium H-shaped; pregonite shorter than postgonite, narrow apically in ventral view; phallus with a pair of teeth-like subapical processes in ventral view; phallapodeme as long as phallus.

FEMALE. Unknown.

Type material. CHINA, Shaanxi Province: Holotype ♂ ( IMAU), Foping County, yueba, Heilongtan, 27. VIII. 2014, Xiumei Lu . Paratypes ( IMAU): 1♂, data same as holotype ; 1♂, Foping County, Daguping, 1329.2 m, 24. VIII. 2014, Xiumei Lu ; 1♂, Yang County, Evergreen fir flat, 29.VII. 2006, Yajun Zhun .

Distribution. China (Shaanxi).

Remarks. The new species is similar to Homoneura (Homoneura) chinensis Malloch, 1926 from China (Sichuan), but the latter has a brown apical spot on M 1 and a sharp apical process on the surstylus. The new species is also similar to Homoneura (Homoneura) dadongshannica Shi & Yang, 2014 from China (Guangdong), but the latter has a brown apical spot on M 1 and the acrostichal setulae in irregular 10 rows on mesonotum.

Etymology. The new species is named after Miao Liu who works hard with me.
