Lispocephala mucronata sp. n.

( Figs 65–70 )

Holotype: male, Wulumuqi city (43°46’N, 87°40’E), Xinjiang, 980 m, 8. ix. 1959, collected by SHUYONG WANG.

Paratype: male, Baiguerte (39°42’N, 75°15’E), Wuqia County, Xinjiang, 2300 m, 19. vi. 1959, collected by SHUYONG WANG .

Male: Body length 3.0 mm.

Head: Eyes bare, lower posterior margin not concave. Frons about 0.38 times as wide as head, lateral margins parallel. Frontal vitta black in ground colour, hardly with faint pruinosity. Frontal triangle with yellow-gray pruinosity, reaching anterior margin of frons. Ocellar developed, longer than frons width. Outer vertical seta longer than posterior vertical, about 1/2 of ocellar. Fronto-orbital with faint gray pruinosity. Distance between orbital setae about 1.5 times as long as that between frontal setae. Parafacial and gena with gray pruinosity. Parafacial about 1/2 of flagellum 1 width. Gena about 1/11 of eye height. Occiput dark, with gray pruinosity. Antenna red-yellow, apical half of flagellum 1 brown-yellow. Flagellum 1 about twice as long as pedicel. Distance between end of antenna and epistoma about 1/2 of flagellum 1 length. Arista short ciliated in basal half, the longest hair about 2/3 of flagellum 1 width, arista bare in apical half. Palpi yellow, prementum dark brown.

Thorax: Dark in ground colour, with faint gray pruinosity, without vitta. Acr in two rows. 2+3 dc, anterior prst dc about 1/2 of posterior one length. 0+2 ial. 2 proepisternal setae, 2 proepimeral.

Wings: Hyaline. Costal spine well marked. Calypters yellow to white. Lower calypter about 1.5 times as long as upper. Halters yellow.

Legs: Coxa and basal 3/4 of femur black-brown, remaining brown-yellow. Mid femur with 1 row of av, seta-liked, longer than tibia diameter, 1 supra-median a, 2 subapical pd, 2 short pv in basal 1/3. Mid tibia with 1 pd, 1.5 times as long as tibia diameter. Hind femur with 1 row of av, 2 subbasal cerci, posterior view (scale bar: 0.2 mm); 70 = lobe of sternite 5, profile view (scale bar: 0.2 mm) short, 2 pv in basal 1/3, 1 short subapical pv. Hind tibia with 1 av, 2 ad, 2 pd, 1 subapical d, as long as tarsomere 1 length. Pulvilli oval.

Abdomen: Oviform, apical part narrow, longer than thorax, posterior margins of abdominal tergites 2–4 yellow, remaining dark black in ground colour, with gray pruinosity. Tergites 2–4 with faint median vittae, tergites 3–5 each with 1 pair of black rounded lateral spots, spot width about 1/2–2/3 of tergite length respectively. Tergite 5 with developed discal and posterior marginal setae, tergite 8 with 2 short setae. Lateral lobes of sternite 5 with apical long setae. End of cerci acuate.

Female: Unknown.

Etymology: This specific name is from the Latin words mucronate, meaning acuate, referring to the new species resembles L. apicaliseta XUE & ZHANG, 2006 , but male end of cerci very acuate ( Fig. 69 ).

Remarks: Resembles L. apicaliseta XUE et ZHANG, 2006 , but can be recognized by in lateral view, male fore margin of surstyli straight; in posterior view, cerci in basal 2/5 ( Fig. 69 ); end of cerci acuate.
