Lispocephala bomiensis sp. n.

( Figs 2–7 )

Holotype: male, Bomi County (29°55’N, 95°45’E), Tibet Autonomous Region, 2300 m, 13. vi. 1978, collected by Fasheng Li.

Paratypes: 2 males, same data as holotype .

Male: Body length 2.4–3.3 mm.

Head: Eyes bare, lower posterior margin not concave. Frons about 0.35 times as wide as head, lateral margins parallel, narrowing towards lunule. Frontal vitta black, with faint yellow-gray pruinosity. Frontal triangle with yellow-gray pruinosity, reaching anterior margin of frons. Ocellar seta as long as or longer than frons width. Outer vertical seta 1.5 times as long as posterior vertical, shorter than ocellar. Fronto-orbital plate with yellow-gray pruinosity. Distance between orbital setae longer than that between frontal setae. With 1–2 small hairs between frontal setae and eyes. Face and gena dark in ground colour, with pale pruinosity. Parafacial brown-yellow in ground colour, with faint yellow pruinosity, about 0.25 times as wide as flagellum 1. Gena about 1/12–1/16 of eye height. 6 = lobe of sternite 5, profile view (scale bar: 0.2 mm); 7 = phallosome (scale bar: 0.2 mm) With 2 short and fine hairs above vibrissa. Profrons not projecting. Basal third of flagellum 1 red-yellow, apical 2/3 black-brown; flagellum 1 twice as long as pedicel; distance between end of antenna and epistoma about 2/5 of flagellum 1 length; arista short ciliated in basal 1/3, the longest hair about 2/3 of flagellum 1 width, bare in apical 2/3. Occiput black in ground colour, with gray pruinosity and black hairs. Palpi red-yellow, prementum black-brown.

Thorax: Black in ground colour, with gray pruinosity, with 3 faint brown vittae. 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: Faint brown, veins dark brown. Costal spine distinct. Calypters faint yellow. Lower calypter about 1.5 times as long as upper. Halters yellow.

Legs: Coxa and femur dark brown, with faint gray pruinosity; trochanter, tibia and tarsi yellow-brown, tarsomere 1 dark yellow. Mid femur with 1 row of long av (3–4 times as long as the diameter of mid tibia in basal half), 2–3 rows of anterior long bristle in basal half, shorter than av, 1 supra-median a, 2 subapical pd, 4–6 pv in basal half. Mid tibia with 1 median pd, about twice as long as the diameter of tibia. Hind femur with 1 row of av and ad, 1 subapical pv, 2 pv in basal 1/3. Hind tibia with 1 av, 2 ad, 2 pd (supra-median one as long as tibia diameter). Pulvilli small, oval, shorter than claws, claws about 1/5 of tarsomere 5 length.

Abdomen: Black-brown in ground colour, with dense gray pruinosity. Long-oviform in dorsal view, longer than thorax, widening backward half in lateral view. With faint median vitta, tergite 4 with 1 pair of faint lateral spots; tergite 5 with 1 pair of black and rounded lateral spots, in dorsal view, spot width about 1/3 of tergite 5 length, 4 discal and 4 marginal setae, developed. Tergite 8 with 2 discal setae. Lateral lobes of sternite 5 red-yellow, with dense long hairs. Sternite 1 bare, sternites 2–5 with long hairs in ventral surfaces.

Female: Unknown.

Etymology: The new species is named after the county of the type locality.

Remarks: Resembles L. secura MA, 1981 , but can be recognised by he scape and pedicel dark brown; face and facial ridge dark in ground color; abdominal tergite 3 without lateral spots; in posterior view, free part of cerci short ( Fig. 2 ).
