Lispocephala dynatophallus sp. n.

( Figs 8–13 )

Holotype: male, Diaokou (36°25’N, 111°4’E), Pu County, Shanxi Province, 11. x. 1980, collected by Mingfu Wang.

Paratype: male, same data as holotype.

Male: Body length 4.5 mm.

Head: Eyes bare, lower posterior margin not concave. Frons at vertex about 0.33 times as wide as head, lower part wider. Frontal vitta dark drown, without gray pruinosity. Frontal triangle with gray-yellow pruinosity, reaching anterior margin of frons. Ocellar developed, about as long as upper orbital seta. Outer vertical seta longer than posterior vertical and shorter than ocellar. Face with gray-white pruinosity. Parafacial with faint yellow pruinosity, 2/5 of flagellum 1 width. Apical 2/3 of flagellum 1 dark drown, basal third brown-yellow. flagellum 1 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 times as long as arista basal diameter, bare in apical half. Profrons projecting. Gena black in ground colour, with gray pruinosity, about 1/14 of eye height. Occiput dark in ground colour, with black hairs and gray-white pruinosity. Palpi red-yellow, about 1.2–1.4 times as long as prementum. Prementum black-brown, about 2.2 times as long as high. Labella with 1 pair of big teeth in each side, 4/5 of fore claws length.

Thorax: Black in ground colour, with gray-white pruinosity; dorsal surface of scutum and scutellum with gray-brown pruinosity, without vitta. Acr in two rows, hair-liked. 2+3 dc, anterior prst dc about 1/2 of posterior one length. 0+2 ial. 2 proepisternal setae; 2 proepimeral.

12 = lobe of sternite 5, profile view (scale bar: 0.2 mm); 13 = terminalia, profile view (scale bar: 0.2 mm)

Wings: Faint brown. Basicosta yellow. Costal spine longer than crossvein r-m. Calypters faint yellow. Lower calypter about 1.3 times as long as upper. Halters yellow.

Legs: Mid and hind coxa black-brown, remaining brown-yellow. Mid femur with 1 supra-median a, 2 subapical pd, 2 pv in basal 2/5. Mid tibia with 1 median pd, without ad. Hind femur with 1 row of av and ad, 2–3 pv in basal 2/5. Hind tibia with 1 av, 2 ad, 2 pd. Pulvilli oval, small, shorter than claws, claws about 2/3 of tarsomere 5 length.

Abdomen: In ventral view, basal half yellow-brown, lateral lobes of sternite 5 yellow, remaining black-brown, with gray-white pruinosity. Long-oviform in dorsal view, longer than thorax, back half wider in lateral view, without median vitta, tergites 3–5 each with 1 pair of black-brown rounded lateral spots (spots of tergite 3 faint), spot width about 2/5 of tergite length respectively. Tergite 5 with 4 discal and 4 marginal setae. Tergite 8 with 2 setae. Aedeagus thick and strong, curving forward.

Female: Unknown.

Etymology: The species name is from the Greek words dynatos meaning muscular, phallos meaning aedeagus, referring to the thick and strong aedeagus ( Fig. 11 ).

Remarks: Resembles L. bomiensis sp. n., but can be recognised by the pedicel red-yellow; femur yellow; mid femur without fine and long hairs; basal part of paraphallus without villi zone ( Fig. 1 ), juxta broad; in lateral view, apical part of surstyli broad.
