  • Homoneura (Homoneura) lii sp. nov. (Figs 7–12) Body length 5.1–5.8 mm (male), 5.3–6.1 mm (female); wing length 5.7–6.4 mm (male), 5.5–6.1 mm (female). Head yellow. Frons wider than long, parallel­sided, with 2 pale brown stripes; ocellar triangle brown; ocellar bristle developed, longer than anterior fronto­orbital bristle; face without spots; gena about 1/4 height of eye. Antenna yellow; 1 st flagellomere somewhat pale brown, about 1.5 times as long as wide; arista black except yellow­brown base, with longest hairs as long as 1/2 width of 1 st 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 6 regular rows and equal in length, prsc about as long as anteriormost dc. Legs yellow. Fore femur with 5 posterior ventral bristles, 6 posterior dorsal bristles, and ctenidium with 12 short bristles. Mid femur with 6 anterior bristles; mid tibia with 1 preapical anterior dorsal bristle and 3 apicoventral spurs. Hind trochanter and femur without secondary characters. Wing (Fig. 7) pale yellow, dark on apex of subcostal cell, subapically on R 2+3, and preapically on R 4+5 and M 1, and along crossvein dm­cu; spots on R 2+3 and R 4+5 confluent; preapical spot on M 1 pale and small; costa with 2nd, 3rd and 4th sections in proportion of 11.5:2:1.4; r­m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 6.1:3.8; ultimate section of CuA 1 about 1/6 of penultimate. Halter yellow. Abdomen yellow, with central black stripes on tergites 3–8 and black edges on tergites 3–6 in male. Male sternite 5 with concave distal border. Genitalia (male) (Figs 8–12): Protandrium rather wide, semicircular, 7th spiracle without surrounding setulae; surstylus basally fused with epandrium, apically furcated, with two outer processes; hypandrium with apodemes small, gonopod divaricated; aedeagus long, without apical incision. Type material. Holotype male deposited in CAU, Guizhou: Fanjingshan Mountain (27°55'N, 108°41'E) (2100–2200 m), 2002. V. 31, Ding Yang. Paratypes 2 males 3 females, same as holotype; 2 males 2 females, Guizhou: Fanjingshan Mountain (27°55'N, 108°41'E) (1800–2200 m), 2002. VI. 1, Ding Yang. Remarks. The new species is similar to Homoneura (Homoneura) bistriata (Kertész, 1915) from Taiwan, but can be separated from the latter by the spots of the subcostal cell and r­m being separated, and the hypandrial apodemes are small. In bistriata, the spots of subcostal cell and r­m are confluent, and the hypandrial apodemes are distinct (Kertész 1915; Sasakawa & Ikeuchi 1982). Etymology. The species is named after Professor Zizhong Li. Distribution. China (Guizhou).
