Lispocephala longihirsuta sp. n.

( Figs 42–46 )

Holotype: male, Kuerle city (41°40’N, 86°3’E), Xinjiang, 1080 m, 16. vii. 1958, collected by CHANGQING LI.

Paratype: male, same data as holotype.

Male: Body length 2.9 mm.

Head: Eyes bare, lower posterior margin not concave. Frons about 0.38 times as wide as head, lateral margins parallel. Frontal vitta dark in ground colour, with dense gray-white pruinosity. Frontal triangle faint, with faint gray pruinosity, reaching anterior margin of frons. Ocellar longer than frons width. Outer vertical seta as long as posterior vertical, about 1/2 of ocellar seta length. Fronto-orbital plate dark, with faint gray-white pruinosity. 2 orbital setae, lower one longer than upper one. 2 frontal setae, lower one about 1/2 of upper one. With 2 hairs between frontal setae and eye. Distance between orbital setae longer than that between frontal setae. Profrons projecting. Face, Parafacial and dark, with faint gray-white pruinosity. Parafacial narrow, 1/4 of flagellum 1 width. Gena dark, about 1/12 of eye in height. Occiput with gray-white pruinosity. Apical margin of pedicel and basal half of flagellum 1 yellow, apical half of flagellum 1 brown yellow. Flagellum 1 about twice as long as pedicel. Distance between end of antenna and epistoma about 2/3 of flagellum 1 length. Arista short ciliated in basal half, the longest hair about 1/3 of flagellum 1 width, times as long as arista basal diameter, bare in apical half. Palpi yellow. Prementum black-brown.

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

Wings: Brown-yellow. Costal spine not marked. Calypters faint yellow. Lower calypter about 1.5 times as long as upper.

Legs: Coxa, fore and hind femur basal 1/5, mid femur basal 3/4 dark brown, remaining yellow. Mid femur with many long and fine ventral hairs in basal 1/3, without av, 1 supra-median a, 2 subapical pd, 1 supra-median pv. Mid tibia with 1 pd, 1.5 times as long as tibia diameter. Hind femur with many long and fine ventral hairs in basal 1/4, 4–5 av, 1 subapical pd, 1 long supra-median pv, 1 short subapical pv. Hind tibia with 1 av, 2 ad, 2 pd. Pulvilli oval, small.

Abdomen: Oval in dorsal view, dark brown in ground colour, with faint gray pruinosity. Tergites 2–4 posterior margin yellow. Tergites with faint median vittae. Tergites 3–5 each with 1 pair of dark brown rounded lateral spots, spot width about 1/3–1/2 of tergite length respectively. Tergite 5 with developed posterior marginal setae, lateral setae undeveloped, tergite 8 with 2 setae. Sternite 4 posterior half and sternite 5 with dense fine and long hairs.

Female: Unknown.

Etymology: The specific name refers to male cerci with long setae ( Fig. 44 ). Longus means long and hirsutus means hairy in Latin.

Remarks: Resembles L. bomiensis sp. n, but can be recognised by scape, pedicel and apical half of flagellum 1 faint brown, basal half of flagellum 1 yellow; fore and hind femur yellow in apical 4/5, mid femur yellow apical 1/4; abdominal tergites 3 with 1 pair of dark brown rounded lateral spots; L-shaped paraphallus.
