description: <i>Homoneura (Chaetohomoneura) setuligera</i> sp. nov. (Figs. 1–6) Body length 6.3–6.7 mm (male); wing length 6.0– 6.7 mm (male). Female (unknown). Head yellow. Frons about as long as wide and parallel­sided, with 2 brown stripes extending to ocellar triangle; ocellar triangle with brown edge; ocellar bristle developed, about as long as anteriormost fronto­orbital bristle; face without spots; gena about 1/5 height of eye. Antenna yellow; 1st flagellomere 1.6 times as long as wide; arista black except yellow base, with longest hairs as long as width of 1st flagellomere. Proboscis yellow, with black and yellow hairs; palpus yellow, with black hairs. Thorax yellow. 0+3 dc (anteriormost dc clearly behind transverse scutal suture), acr in 8–9 somewhat irregular rows and equal in length, prsc longer than 1st post­sutural dc, 2 sa (anterior seta loner than posterior one). Legs yellow. Fore femur with 5 posterior ventral bristles, 7 posterior dorsal bristles, and ctenidium with 12 short bristles. Mid femur with 6 anterior bristles; mid tibia with 1 preapical anterior dorsal bristle, 7 posterior dorsal bristles and 4 apicoventral spurs. Hind trochanter and femur without secondary characters. Wing (Fig. 1) pale yellow, lightly darkened at apex of R 2+3, subapically on R 4+5 and M 1 and along crossvein dm­cu; spots on R 2+3 and R 4+5 confluent and connecting with spot on M 1; costa with 2nd (between R 1 and R 2+3), 3rd (between R 2+3 and R 4+5) and 4th (between R4+5 and M) sections in proportion of 5:1.2:0.9; r­m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 3:2.4; ultimate section of CuA 1 about 1/8 of penultimate. Halter yellow. Abdomen yellow, edges of tergites 1–6 black brown. Male sternite 5 with concave distal border. Genitalia (male) (Figs. 2–6): Protandrium rather wide, circular, with a setula, and 7th spiracle with surrounding setulae; surstylus basally fused with epandrium, apically not furcate, with oblique acute tip in lateral view; hypandrial apodemes small, gonopod long; aedeagus long, with apical incision. Type material. Holotype male deposited in CAU, Guizhou: Fanjingshan Mountain (27°55'N, 108°41'E) (600 m), 2002. VI. 3, Ding Yang. Paratype 1 male, same as holotype. Remarks. The new species is somewhat similar to <i>Homoneura (Chaetohomoneura) fuscicostata</i> (Walker, 1856) from Malaysia, but can be separated from the latter by the short hypandrial apodemes. In <i>fuscicostata</i>, the hypandrial apodemes are long (Sasakawa 1992). Etymology. The species is named after 7th spiracle with surrounding setulae. Distribution. China (Guizhou).
