Lispocephala applicatilobata sp. n.

( Figs 30 –35)

Holotype: male, Tuqiang town (53°28’N, 122°22’E), Heilongjiang Province, 28. iv. 1979, collected by Changyuan Cui.

Paratype: male, same data as holotype.

Male: Body length 4.7 mm.

Head: Eyes bare, lower posterior margin not concave. Frons at vertex about 0.37 times as wide as head, lateral margins nearly parallel. Frontal vitta black. Frontal triangle with faint gray pruinosity, reaching anterior margin of frons. Ocellar developed, longer than frons width. Outer vertical seta as long as posterior vertical, about 2/3 of ocellar. Profrons projecting. Frontal angle nearly right-angle. Face in the lower 1/3 and facial ridge red-yellow. Lower part of parafacial red-yellow, parafacial with faint gray pruinosity, 2/5 of flagellum 1 width. Vibrissa with 2 setae. Gena red-yellow on foreside, about 1/6 of eye height. Occiput black in ground colour, with faint gray pruinosity. Pedicel red-yellow, flagellum 1 black-drown. Flagellum 1 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 as long as arista basal diameter, bare in apical half. Palpi red-yellow, prementum black-brown.

Thorax: Dark in ground colour, with faint gray pruinosity, without vitta. Acr in two rows, 2+3 dc, anterior prst dc as long as posterior. 0+2 ial. 2 proepisternal setae, 2 proepimeral.

Wings: Veins yellow. Basicosta brown. Costal spine distinct. Area around crossvein r-m and dm-cu brown clouded. Calypters white, margin red-yellow. Lower calypter about 1.5 times as long as upper. Halters red-yellow.

Legs: Coxa and femur black, with faint gray pruinosity. Trochanter, tibia and tarsi red-yellow (apical part of tarsi brown). Mid femur with 1 row of av, twice as long as mid tibia diameter, 1 supra-median a, 2 subapical p, 1 row of developed pv (9–10). Mid tibia with 1 supra-median pd, 2.5 times as long as tibia diameter. Hind femur with 1 row of av, ad and pv, all developed and completed, 1 subapical pd. Hind tibia with 2 av, 2 ad, 2 pd, 1 subapical d, long, about 3/5 of hind tibia length. Claws and pulvilli big, long-rounded, about 4/5 of tarsomere 5 length.

Abdomen: Oval in dorsal view, longer than thorax, in ventral view, tail half widening. Syntergite 1+2, posterior margins of tergites 3–4 yellow, remaining black, with faint gray pruinosity, without median vitta, tergites 3–5 each with 1 pair of black rounded lateral spots, spot width about 2/5–1/3 of tergite length respectively. Tergite 5 with developed discal and posterior marginal setae, lateral setae dense and long, most longer than tergite. Tergites 7–8 each with 6 developed marginal setae. Basal part of lateral lobe of sternite 5 projecting ( Figs 31–32 ). In posterior view, cerci with narrow longitudinal ridge in apical 2/3 ( Fig. 30 ). Basal lateral process of apical distiph developed, dorsal process strip-liked (Fig. 35).

Female: Unknown.

Etymology: The specific name refers to male basal part of lateral lobe of sternite 5 projecting.

Applicatus means attached and lobatus means lobed in Latin.

Remarks: Resembles L. securisocialis (XUE et al. 1998) , but can be recognised by face in the lower 1/3 and facial ridge red-yellow; foreside of gena red-yellow; flagellum 1 black-brown; mid femur with 1 row of developed pv (9–10); basal nalia, profile view (scale bar: 0.2 mm); 34 = paramere (scale bar: 0.1 mm)

part of hind femur black; hind tibia with 2 av; abdominal epandrium projecting backwards; basal part of lateral lobe of sternite 5 with process; in posterior view, cerci with narrow longitudinal ridge in apical 2/3, in lateral view, posterior margin of cerci straight in middle part.
