Nicephora dianxiensis Wang & Liu sp. nov.

( Figs. 33–39 )

Materials. Holotype ♂, paratypes: 3♂♂, 1♀, China: Yunnan, Lushui country, Yaojiaping, 2700m, 2010. VI.21–23, leg. BI-Wenxuan.

Description. Male. Fastigium of vertex conical, with weak dorsal groove. Pronotum long and low, metazona very long, hind margin little point. Tegmina almost as long as pronotum, reaches base of 7th abdominal tergite, apex pointed, venation clear. Fore tibiae with spines armed 3, 3 (1, 1), mid tibiae with 3 inner and 3 outer spines, hind tibiae each margin above with 20~22 dorsal teeth and 2 pairs of apical spurs. 10th abdominal without lobes, hind margin little sinuate; cerci with small pointed upper medial process, lower process foliaceous, down curved, apex with 2 teeth ( Figs. 34, 36–38 ); middle part incurved, apical part straight and apex rounded. Genitalia with a pair of upper protruding and lower rounded sclerites ( Fig. 37 ). Subgenital plate is longer than wide, apical part of each side in front of styli with a weak carina, hind margin notched, styli short ( Fig. 36 ).

Female. Metazona shorter, more pointed. Tegmina short, interlaced. Subgenital plate almost triangular, with axis grooved deeply, hind margin pointed ( Fig. 39 ). Ovipositor with very weak apical hook.

Coloration. Pale brownish, antennae with darkish rings. Base of each tibiae with a darkened spot. Dorsal of abdominal with a longitudinal darkish band.

Measurement. (length in mm) Body: ♂8.5–9.5, ♀7.0; pronotum: ♂4.4–4.6, ♀4.0; tegmina: ♂4.0–4.2, ♀3.5; hind femora: ♂6.9–7.8, ♀8.5; Ovipositor 8.2.

Discussion. This new species without densely denticulate apex in male cerci, integrated features are very close to Eunicephora in type of male cerci and number of genital sclerites; it distinguishes with the preceding species by processes of male cerci and the shape of sclerites in genitalia.

Distribution. China (Yunnan)
