Homoneura (Homoneura) brevituba View in CoL sp. nov.
( Figs. 2, 13, 24, 35, 47–51)
Diagnosis. Face without spots. Antenna brown except yellow basally on 1st flagellmere. Wing slightly yellow, without markings. Abdominal tergite 2 with a pair of blackish brown lateral posterior bands; tergites 3–5 each with a black posterior band; tergite 6 with a small brown median spot.
Description. MALE. Body length 3.0– 3.2 mm, wing length 3.0– 3.3 mm.
Head ( Fig. 2) pale yellow. Face without spots. 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 strong, about as long as anterior or, anterior or slightly shorter than posterior or. Gena about 1/7 height of eye. Occiput with a wide grayish black stripe confluent with ocellar triangle. Antenna brown except yellow basally on 1st flagellmere, 1st flagellomere 1.7 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. 13) blackish brown with grayish white pruinescence. Mesoscutum with white pruinescence on anterior margin, 0+3 dc (anterior dc clearly behind transverse scutal suture), acr in 8 somewhat irregular rows. Anepisternum blackish brown except yellow posterior ventral corner, pteropleuron and dorsal margin of katepisternum blackish brown. 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 13–14 short bristles; fore tibia with 1 long preapical ad and 2 short apv. Mid femur with 6 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. 24) slightly yellow, without markings; 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 1.4: 0.5: 0.3; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.1: 0.7; ultimate section of CuA 1 about 1/5 of penultimate. Halter pale yellow.
Abdomen ( Fig. 35) yellow with sparse silvery white pruinescence; tergite 2 with a pair of blackish brown lateral posterior bands; tergites 3–5 each with a black posterior band; tergite 6 with a small brown median spot (sometimes absent). Male genitalia ( Figs. 47–51): protandrium circular; epandrium nearly oblong and surstylus incurved claviform in lateral view; hypandrium with a pair of excurved ventral processes, without hypandrial apodeme; gonopod columniform with apex incurved in ventral view; aedeagus apodeme short; aedeagus with distinct apical incision, consisting of a pair of dorsal sclerites and a pair of dorsal apical teeth.
FEMALE. Unknown.
Type material. Holotype ♂ ( CAU), CHINA, Yunnan Province: Xishuangbanna, Mengla, Bubeng Village , 8. V. 2009, Guoquan Wang . Paratype: CHINA, Yunnan Province: 1 ♂ ( CAU), Xishuangbanna, Mengla, Bubeng Village , 8. V. 2009, Guoquan Wang .
Distribution. China (Yunnan).
Remarks. The new species is somewhat similar to Homoneura (Homoneura) apicomata Shi & Yang from China (Yunnan and Hainan) in the following characters: face without spots; abdominal tergite 2 with a pair of blackish brown lateral posterior bands; tergites 3–5 each with a black posterior band; protandrium circular;
epandrium nearly oblong and surstylus incurved claviform in lateral view; gonopod columniform; hypandrium with a pair of excurved ventral processes, without hypandrial apodeme; aedeagus with distinct apical incision, consisting of a pair of dorsal sclerites and a pair of dorsal apical teeth. But it can be separated from the latter by the following features: wing without brown stripe on dm-cu; abdominal tergite 6 with a small brown median spot; aedeagal gonopod incurved at apex in ventral view; aedeagal apodeme short. In H. (H.) apicomata , the wing has a brown stripe on dm-cu; the abdominal tergite 6 has no median spot; the aedeagal gonopod is excurved at apex in ventral view; the aedeagal apodeme are long (Shi & Yang 2009).
Etymology. Latin, brevi -, prefix meaning short + tuba, meaning tube, referring to the aedeagal apodeme being short.
