Homoneura crispa sp. n. Male. (11) Body, lateral view (apical portion of abdomen removed). (12) Wing. (13) Head, dorsal view. (14) Mesoscutum, dorsal view. (15) Abdomen, dorsal view.

Head (Fig. 13) yellow. Frons about as wide as long and parallel-sided, with 2 brown lateral bands; ocellar triangle black brown; oc strong, about as long as anterior or; anterior or shorter than posterior or. Gena about 1/5 height of eye. Antenna yellow; 1st flagellomere yellow except brown one side, 1.6 times longer than high; arista black except brown basally, with longest hairs about 1/4 width of 1st flagellomere. Proboscis brownish, with blackish and yellowish hairs; paplus yellowish, with black hairs.

Thorax (Fig. 14) brownish, with grayish white pruinescence. Mesoscutum with 1 wide blackish brown median band extending to apical margin of scutellum, 0+3 dc, anterior dc close to transverse scutal suture, acr in 6 rows, prsc shorter than anterior dc. Legs yellow. Fore femur with 5 strong pv and 7 pd, ctenidium with 9-10 short bristles; fore tibia with 1 long preapical ad and 1 short apv. Mid femur with 7 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. 12) slightly yellow, with 5 brown spots, dark on dm-cu, r-m, preapices of R 2+3, R 4+5 and M 1; preapical spots of R 4+5 and M 1 confluent; subcostal cell brownish; 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 12: 2.8: 2.3; r-m before middle of discal cell; ultimate and penultimate

sections of M 1 in proportion of 1.8: 1.0; ultimate section of CuA 1 about 1/8 of penultimate. Halter pale yellow.

Abdomen (Fig. 15) brown, with grayish white pruinescence; tergites 2-6 each with a black band at posterior margin, and tergites 3-6 with a narrow black median band. Male genitalia (Figs 16-20): protandrium circular, with setulae above spiracle; surstylus bifurcated, anterior one with hairs, and longer than posterior one; hypandrium Y-shaped, hypandrial apodemes not distinct, gonopod long; aedeagus curled towards dorsum and acuted apically, with pair of lateral spurs medially.

Female: Unknown.

DISTRIBUTION: China (Yunnan).

REMARKS: The new species resembles H. suturalis Yang, Zhu & Hu from China (Fujian) in the following characters: wing with similar pattern, preapical spots of R 4+5 and M 1 confluent; anterior dc close to transverse scutal suture; abdominal tergites with a black median band. But it can be separated from the latter by the following features: face without spots; mesoscutum with 1 wide blackish brown median band extending to apical margin of scutellum; subcostal cell of wing brownish; abdominal tergites 2-6 each with a black band at posterior margin. In H. suturalis , the face has a brown spot; the mesoscutum has no darkened bands; the subcostal cell of the wing is hyaline; abdominal tergites 2-6 each has a black band at the posterior margin ( Yang, Zhu & Hu 2003).
