Lispocephala subcurvilobata sp. n.

( Figs 59–64 )

Holotype: male, Mt. E’mei (29°36’N, 103°25’E), Sichuan Province, 1800–2000 m, 23. v. 1957, collected by KEREN HUANG.

Paratype: male, Laochang town (25°41’N, 104°25’E), Pan county , Guizhou province, 18. ix. 1984, collected by LIANMENG WEI .

Male: Body length 2.4 mm.

Head: Eyes bare, lower posterior margin not concave. Frons at vertex about 0.34 times as wide as head, lateral margins parallel, lower part narrowing. Frontal vitta black in ground colour, with yellow-gray pruinosity. Frontal triangle wide, with yellow-gray pruinosity, reaching anterior margin of frons. Ocellar developed, 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. Face with gray-white pruinosity. Parafacial with faint yellow pruinosity, 1/4 of flagellum 1 width. Vibrissa angle with 2 short setae. Gena with gray-white pruinosity, about 1/16 of eye height. Occiput black in ground colour, with faint gray pruinosity. Pedicel and apical part of flagellum 1 red-yellow, remaining red-brown. Flagellum 1 about twice as long as pedicel. Distance between end of antenna and epistoma about 2/5 of flagellum 1 length. Arista short plumose in basal 1/3, the longest hair about 2/3 of flagellum 1 width, bare in apical 2/3. Palpi yellow, prementum black-brown.

(scale bar: 0.1 mm); 63 = paramere (scale bar: 0.1 mm); 64 = terminalia, profile view (scale bar: 0.2 mm)

Thorax: Black in ground colour, with faint gray pruinosity, without vitta (sometime with 2 brown faint vittae), with faint brown pruinosity. Acr in two rows, slightly developed. 2+3 dc, anterior prst dc about 3/5 of posterior one length. 0+2 ial. 2 proepisternal setae, 2 proepimeral.

Wings: Brown, posterior margins light, veins dark brown. Costal spine well marked. Calypters faint yellow. Lower calypter about 1.5 times as long as upper. Halters yellow.

Legs: Apical part of femora, trochanters, tibiae and tarsi yellow, remaining black. Mid femur with many long and fine av, 4–5 times as long as mid tibia diameter in basal half, 1 supra-median a, 2 subapical p, in basal half, 2–4 pv. Mid tibia with 1 medial pd, twice as long as tibia diameter. Hind femur with 1 row of av and ad, 1 subapical pd, 2 basal half pv. Hind tibia with 1 av, 2 ad, 2 pd (subbasal twice as long as submedial). Pulvilli oval, small.

Abdomen: Long-oviform in dorsal view, longer than thorax, dark black in ground colour, with gray pruinosity, without median vitta. Abdominal tergites 4–5 each with 1 pair of black rounded lateral spots, spot width about 1/3 of tergite length respectively. Tergite 5 with developed discal and marginal setae, tergite 8 with 2 discal setae. Sternites 2–5 with long hairs, dense in sternite 5 ( Fig. 60 ).

Female: Unknown.

Etymology: This specific name is from the Latin words sub-, meaning similar, referring to the new species resembles L. curvilobata sp. n.

Remarks: Resembles L. curvilobata sp. n, but can be recognized by male apical part of femora yellow, remaining black; paraphallus broad and short ( Fig. 59 ); in lateral view, basal part of surstyli projecting backward, beyond cerci ( Fig. 64 ), anterior artus of paramere short.
