description: Lispocephala apertura sp. n.   (Figs 47–52)  Holotype: male, Damenglong (21°58’N, 100°47’E), Xishuangbanna, Yunnan province, 650 m, 22. iv. 1958, collected by YIRAN ZHANG.  
Paratype: male, same data as holotype.  
Male: Body length 2.8 mm.  
Head: Eyes bare, lower posterior margin not concave. Frons at vertex about 0.33 times as wide as head, lower part becoming wide. Frontal vitta black-brown in ground colour, nearly without 0.2 mm); 51 = lobe of sternite 5, profile view (scale bar: 0.1 mm); 52 = paramere (scale bar: 0.1 mm) pruinosity. Frontal triangle with yellow-gray pruinosity, reaching anterior margin of frons. Ocellar developed, as long as frons lower part width. Outer vertical seta longer than posterior vertical, about 2/3 of ocellar. Fronto-orbital with gray-white pruinosity. Distance between orbital setae longer than that between frontal setae. Parafacial with gray-white pruinosity, narrow, 1/4 of flagellum 1 width. Gena with gray-white pruinosity, about 1/12 of eye height. Occiput black in ground colour, with dense gray-white pruinosity. Apical margin of pedicel and basal half of flagellum 1 red-yellow, remaining brown. Flagellum 1 about 2.2 times 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 about 2/3 of flagellum 1 width, bare in apical half. Palpi yellow, prementum black-brown.  
 Thorax: Dark black in ground colour, with faint gray pruinosity, without vitta. Acr in two rows, developed. 2+3 dc, anterior prst dc about 1/2 of posterior one length. 0+2 ial. 2 proepisternal setae, 2 proepimeral.   
Wings: Hyaline, veins yellow. Costal spine well marked. Calypters yellow to white. Lower calypter about 1.5 times as long as upper. Halters yellow.  
 Legs: Coxa and femur dark brown, remaining yellow. Mid femur with 1 row of short av, about 1.5 times as long as mid tibia diameter, 2 medial a, 2 subapical pd, 2 pv in basal 2/5, 1–2 seta-liked subapical pv, about 1.5 times as long as mid tibia diameter. Mid tibia with 1 supra-median pd, about twice as long as mid tibia diameter. Hind femur with 4 developed av and 2 short av, 1 subapical pd, in basal 2/5 2 pv, 2 subapical pv. Hind tibia with 1 av, 2 ad (supra-median one long, 1/2 of tibia diameter), 2 pd (supra-median one short, as long as tibia diameter). Pulvilli small, oval.   
Abdomen: Oval in dorsal view, longer than thorax, posterior margins of tergites and lateral lobes of sternite 5 yellow, remaining dark brown in ground colour, with gray-white pruinosity. Abdominal tergites with fainted brown median vittae; tergites 3–5 each with 1 pair of black brown rounded lateral spots, spot width about 1/2–3/4 of tergite length respectively. Tergite 5 with developed posterior marginal setae and discal setae, tergite 8 with 2 discal setae. End of surstyli and cerci cuspidal. Apicialula and dorsialulae of paraphallus slightly sclerotized, 1 pair of auricle-liked laterialulae. In profile, apical part of paraphallus with a small middle posterior window.  
Female: Unknown.  
 Etymology: The specific name refers to male apical part of paraphallus with a small middle posterior window in profile (Fig. 47). Apertura means aperture in Latin.   
 Remarks: Resembles L. pilimutinus XUE et ZHANG, 2006, but can be recognized by apical margin of pedicel and basal half of flagellum 1 red-yellow, remaining brown; coxa and femur dark brown, remaining yellow; mid femur 2 medial a; in profile, apical part of paraphallus with a small middle posterior window; paraphallus without basal villi zone.
