Lispocephala apicihamata sp. n.

( Figs 36–41 )

Holotype: male, Mengzhe (21°56’N, 100°26’E), Xishuangbanna , Yunnan Province, 1750 m, 29. vi. 1958, collected by Shuying Wang.

Paratype: male, same data as holotype.

Male: Body length 3.7 mm.

Head: Eyes bare, lower posterior margin straight. Frons about 0.33 times as wide as head, lateral margins parallel. Frontal vitta black, without pruinosity. Frontal triangle with gray-white pruinosity, reaching to anterior margin of frons. Ocellar seta developed, longer than frons width. Outer vertical seta 1.5 time as long as posterior vertical, distinctly shorter than ocellar. Fronto-orbital plate with gray-white pruinosity. Profrons projecting, frontal angle obtuse. Face, parafacial and gena brown-yellow in ground colour, with yellow-gray pruinosity. Parafacial narrow, about 1/4 of flagellum 1 width. Gena hair black, about 1/17 of eye height. Occiput black in ground colour. Antenna entirely yellow, flagellum 1 about twice as long as pedicel. Distance between end of antenna and epistoma about 1/3 of flagellum 1 length. Arista short ciliated in basal half, the longest hair about 1/3 of flagellum 1 width, bare in apical half. Palpi yellow, prementum dark brown.

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

Wings: Hyaline, veins brown-yellow. Costal spine short. Calypters light yellow. Lower calypter about 1.5 times as long as upper. Halters yellow.

Legs: Entirely yellow. Hind femur with 1 row of av and ad, completed, 1 subapical p, 2 basal half pv, 1 subapical pv. Hind tibia with 1 av, 2 ad, 2 pd, 1 submedial av, long, 1/2 of tibia length, 1 submedial pd, as long as tibia diameter, pulvilli small.

Abdomen: Cylindrical, longer than thorax, long-oviform in dorsal view. Tergites 4–5 and basal half of sternite 5 dark brown, remaining yellow. Ter- Fig. 35. Lispocephala applicatilobata sp. gites 3–4 with faint median vittae respectively; ter- n.: phallosome (scale bar: 0.2 mm) gites 3 with brown lateral spots, faint. Tergites 4–5 with each 1 pair of rounded brown lateral spots, spot width about 1/3–1/2 of tergite length respectively. Tergite 5 with developed discal and posterior marginal setae, lateral setae undeveloped, tergite 8 with 2 pairs of discal setae. Surstyli with apical spinous process forward ( Fig. 41 ). Cerci upper apical part straight ( Fig. 36 ).

Female: Unknown.

Etymology: The specific name refers to male apical hamulus of surstyli. Apicis means apical and hamatus means falcate in Latin. (scale bar: 0.2 mm); 40 = paramere (scale bar: 0.1 mm); 41 = terminalia, profile view (scale bar: 0.2 mm)

Remarks: Resembles L. ungulitigris (FENG et XUE, 1997) , but can be recognised by flagellum 1 yellow in apical half; abdominal tergite 3 entirely yellow; abdominal syntergite 1+2 without spot; lateral lobe of sternite 5 less than twice of basal lobe in length; cerci without apical hamulus; surstyli with apical hamulus.
