Ding Yang ( CAU ). Diagnosis. – Wing with 5 brown spots on tip of R 2+3 to M 1+2 , preapical section of R 4+5 and m-m, apical spots on R 2+3 to M 1+2 more or less connected; subcostal cell dark apically. Description. – Body length 8.5 (male) mm, wing length 8.5(male) mm. Head yellow, with yellow dust. Frons about as long as wide and slightly converging backward, with dark anterior spots; ocellar triangle yellow brown; oc developed; face without spots; cheek about 1/7 height of eye. Antenna yellow; 3rd segment 2 times as long as wide; arista black except yellow base, with longest hairs as long as width of 3rd antennal segment. Proboscis yellow, with black and yellow hairs; palpus yellow, with black hairs. Thorax yellow, with yellow dust; scutellum testaceous. 0+3 dc, acr in 10 rows, 1st post-sutural dc broken. Legs yellow. Fore femur with 4 posterior ventral bristles, 5 posterior dorsal bristles, and ctenidium with 12 short bristles. Mid femur with 7 anterior bristles; mid tibia with 3 spurs. Wing pale yellow, dark on apex of subcostal cell, tip of R 2+3 to M 1+2, preapical section of R 4+5 and m-m; costa with 2nd, 3rd and 4th sections in proportion of 8:2:1.5; r-m before middle of discal cell; ultimate section of M 1+2 1.2 times as long as penultimate; ultimate section of M 3+4 about 1/5 of penultimate. Halter yellow. Abdomen yellow, with yellow dust. Male genitalia ( Figs. 38- 42 ): Protandrium forming a sclerotized band with a ventral segment, with a dorsal protuberance directed forward, without setulae around spiracle ( Fig. 39 ); surstylus on epandrium with distinct inner process; hypandrial apodemes rather weak, gonopod long and rolling up apically; aedeagus long, distinctly incised apically ( Fig. 42 ). Etymology. – The species is named after the type locality Tian’e. Distribution. – China ( Guangxi ). Remarks. – The new species is similar to Homoneura (Homoneura) yaromi Yang, Hu & Zhu, 2001 , from Zhejiang , but can be separated from the latter by frons with spots. In yaromi , the frons has no spots (Yang, Hu & Zhu, 2001).
