Abdominal tergites 2–6 each with a blackish brown median spot, confluent with blackish brown posterior bands on tergites 3–5. Description. MALE. Body length 4.4 mm , wing length 4.8 mm . FEMALE. Body length 4.4–4.8mm , wing length 4.7–4.8 mm . Head ( Fig. 3 ) pale yellow. Face with a large blackish brown median spot. Frons about as long as wide and parallel–sided, with two narrow blackish gray stripes along or rows and a narrow brown triangular median stripe extending to ocellar triangle; ocellar triangle grayish black; oc and anterior or broken. Gena about 1/6 height of eye. Occiput with a wide grayish black stripe confluent with ocellar triangle. Antenna blackish brown except 1st flagellomere brownish, 1st flagellomere 1.6 times longer than high; arista long plumose, blackish brown except brownish basally, with longest hairs longer than height of 1st flagellomere. Proboscis yellowish brown, with yellowish and blackish hairs; palpus pale yellow with blackish hairs. Thorax ( Fig. 14 ) blackish brown with grayish white pruinescence. Mesoscutum with 5 brownish yellow longitudinal stripes. 0+3 dc (anterior dc clearly behind transverse scutal suture), acr in 6 somewhat irregular rows. Anepisternum blackish brown except yellow dorsal margin, and with 1 yellow median stripe, pteropleuron blackish brown, katepisternum yellow. Scutellum brownish black except yellow apical margin, with yellowish gray pruinescence. Legs pale yellow, but all tarsi dark yellow except tarsomere 5 brown on apical half; hind tibia with an incomplete brown basal ring. Fore femur with 4 strong pv and 5 pd , ctenidium with 9 short bristles; fore tibia with 1 long preapical ad and 2 short apv . Mid femur with 5 a and 1 apv ; mid tibia with 1 strong preapical ad and 3 strong apv . Hind femur with 1 preapical ad ; hind tibia with 1 weak preapical ad and 1 short apv . Wing ( Fig. 25 ) slightly yellow, with a narrow brown stripe on dm-cu ; subcostal cell hyaline; costa with 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 2.3: 0.8: 0.4; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.7: 1.2; ultimate section of CuA 1 about 1/6 of penultimate. Halter yellow. Abdomen ( Fig. 36 ) yellow with sparse silvery white pruinescence; tergites 2–6 each with a blackish brown median spot, confluent with blackish brown posterior bands on tergites 3–5. Male genitalia ( Figs. 52–56 ): protandrium circular; epandrium nearly triangular and with a subapical concavity on anterior ventral margin in lateral view; surstylus incurved claviform; hypandrium with a pair of ventral processes, hypandrial apodeme long; gonopod coniform; aedeagal incision distinct, with a pair of dorsal sclerites and a pair of preapical lateral processes. Type material Holotype ♂ ( CAU ), CHINA , Yunnan Province : Kunming , Xishan , Erdaogou , 15. IV. 2007 , Hui Dong . Paratypes : CHINA , Yunnan Province : 1 ♀ ( CAU ), Kunming, Xishan, Erdaogou, 15. IV. 2007 , Hui Dong ; 1 ♀ ( CAU ), Kunming, Xishan, Erdaogou, 15. IV. 2007 , Wenliang Li . Distribution. China ( Yunnan ). Remarks. The new species is somewhat similar to Homoneura ( Homoneura ) convergens Shi & Yang from China ( Hainan ) in the following characters: face with spots; acr in 6 somewhat irregular rows; mesoscutum with brownish yellow longitudinal stripes; wing with a narrow brown stripe on dm-cu ; abdominal tergites 2–6 each with a blackish brown median spot and/or a pair of posterior bands; epandrium with a subapical concavity on anterior ventral margin in lateral view; gonopod coniform. But it can be separated from the latter by the following features: mesoscutum with 5 brownish yellow longitudinal stripes; abdominal tergites 2–6 each with a blackish brown median spot, confluent with blackish brown posterior bands on tergites 3–5?protandrium without ventral processes; surstylus consisting of 1 process. In H . ( H .) convergens , the mesoscutum has 4 brownish yellow longitudinal stripes; the abdominal tergite 2 has a black median spot and tergites 3–4 have a black posterior band, tergite 5 has a black triangular median spot and tergite 6 has a black elliptical spot; protandrium has no ventral process; surstylus is consisting of 2 processes (Shi & Yang 2009). Etymology. Latin, conica , meaning coniform, referring to the gonopod being coniform.
