description: Lispocephala nigriala sp. n.   (Figs 71–77)  Holotype: male, Leidongping, Mt. E’mei (29°21’N, 103°17’E), Sichuan Province, 2400–2690 m, 3. vi. 2009, collected by MINGFU WANG.  
Paratype: male, same data as holotype.  
Male: Body length 3.8–4.0 mm.  
Head: Eyes bare, lower posterior margin not concave. Frons densely grayish dusted, about 0.37 times as wide as head. Frontal vitta black in ground-color, about 2.0–2.4 times as wide as fronto-orbital plate. Frontal triangle with gray-yellow pruinosity, reaching to anterior margin of frons. lunule brownish, with thin faint pruinosity. Ocellar seta strong, about as long as frons width. Inner vertical seta about 2.0 times as long as outer vertical. Fronto-orbital plates and parafacials with brown-gray pruinosity; parafacial about 2/5 of flagellum 1 in width. Gena about 1/10 of eye height; gena, postgena and epicephalon with black hairs. Epistoma not projecting. Vibrissal angle behind the vertical line of profrons in profile. Occiput with blue gray pruinosity; median occipital sclerite bare. Distal 1/3 of pedicel and base of flagellum 1 yellow, remaining part dark black. Arista long-haired on basal 1/3, apical 2/3 bare, the longest hair about 0.6 times as wide as antenna width. Flagellum 1 about 2.5 times as long as wide; the distance between flagellum 1 and epistoma about 3/5 of antenna length. Prementum black, shining, about 2.5 times as long as high. Palpi yellow, as long as prementum, labella length about 1.2 of prementum height.  
 Thorax: Black in ground colour, grayish dusted, without distinct vitta. Acr in 2 rows, hair-like. 2+3 dc, anterior prst -dc about 3/7 of posterior prst -dc length. 0+2 ial, without pra. 2 proepisternal setae (the lower one shorter), 2 proepimeral (the lower one shorter). 1 anterior anepisernal seta.   
 Wings: Brownish, veins brown. Basicosta yellow. Costal spine longer than crossvein r-m. Costa continuing to apex of vein M. Veins R 4+5 and M straight, parallel. Calypters yellowish; lower calypter about 1.6 times as long as upper. Halters faint yellow.   
 Legs: Fore and mid trochanters, apex of femur, tibia and tarsi brown-yellow, remaining black. Fore tibia with 1 subapical p. Mid femur with 1 row of short av (2–3 fine hairs in basal 2/3, the longest one about 4/5 of this tibia diameter), becoming shorter towards apex, 1 median a, 2 apical pd, 2 strong pv in basal half. Mid tibia without ad, 1 supra-median pd, 1 medial pd. Hind femur with 4 av (subbasal 1, supra-median 1, submedial 1, subapical 1), 1 strong pv in basal 1/3, longer than the diameter of mid tibia, sometimes with 1 basal pv, about 1/2 of diameter of mid tibia. Hind tibia with 1 av, 2 ad, view (scale bar: 0.2 mm); 75 = phallosome (scale bar: 0.2 mm)   
 1 sub-basal pd, short, 1 strong pre-apical d. Only fore tarsi longer than tibia. Claws longer than pulvilli, about 3/5 of tarsomere 5 length.   
Abdomen: Black, with dense blue gray to gray pruinosity, without shifting patches. Nearly spindly in dorsal view. Tergites 2–3 each with dark brown median vitta, vitta width as long as the diameter of hind tibia (Fig. 71), without lateral spot; tergites 4 to 5 each with 1 pair of black brown lateral spots and 2–3 discal setae, the distance between lateral spots on tergite 4 wider (Fig. 71), body hairs sparse, lateral body-hairs and setae not becoming long; tergite 6 and sternite 1 bare.  
Female: Unknown.  
 Etymology: This specific name is from the Latin words niger, meaning dark black, ala meaning wing, referring to the new species resembles L. obfuscatipennis (XUE, 1998), but male wing opaque in basal, dark black.   
 Remarks: Resembles L. obfuscatipennis (XUE, 1998), but can be recognised by 2 proepisternal setae; basal part of wing opaque, brown, veins brown; mid tibia with 2 pd; abdomen entirely black; tergite 3 without lateral spot, tergites 2–3 each with median vitta; lateral lobe of sternite 5 with 3–4 long hairs in distal part; free part of cerci longer than basal part; surstyli furcated in distal part (Fig. 73).
