Type material.

Holotype: ♂, China: Yunnan Province, Lushui City, Pianma Town (26°1'N, 98°37'E), 17 June 2011, leg. Yu-Jian Li, Jian-Kun Long; paratypes: 1♂ 1♀, same data as holotype; 6♂♂ 1♀, Guizhou Province, Daozhen County, Xiannvdong Nature Reserve (29°3'N, 107°25'E), 26 August 2004, leg. Xiang-Sheng Chen.

Description.

Body length: male 5.1-6.3 mm (N = 8), female 6.1-6.5 mm (N = 2).

Coloration. General color blackish brown (Figs 1C, D , 4A, B ). Eyes dark brown, ocelli yellowish brown. Vertex dark brown, pronotum dark brown and mesonotum blackish brown. Face generally blackish brown. Rostrum generally dark brown except darker tip. Forewing semi-translucent, stigma blackish brown. Hind tibiae brown and abdominal sternites blackish brown.

Head and thorax. Vertex (Fig. 4A ) broad, 4.2 times wider than long; anterior margin slightly arched convex, posterior margin slightly arched concave; median carina reaching transverse carinae. Frons (Fig. 4B ) 1.2 times as wide as long, median carina indistinct, extending from slightly above level of lateral ocelli to median ocellus. Clypeus with median carina distinct and elevated throughout. Pronotum (Fig. 4A ) 4.4 times longer than vertex, posterior margin nearly at right angle. Mesonotum 1.9 times longer than pronotum and vertex combined. Forewing (Fig. 4C ) 3.1 times longer than wide, with 11 apical and 6 subapical cells; fork Sc+RP distad of fork CuA1+CuA2; first crossvein r-m basad of fork MP; RP 3 branches, MP with five terminals: MP11, MP12, MP2, MP3, and MP4, fork MP1+MP2 basad of fork MP3+MP4. Hind tibia with 3 lateral spines, metatibiotarsal formula: 6/7/8, second segment of hind tarsus with 3 platellae.

Male genitalia. Pygofer (Fig. 4D, E ) symmetrical, dorsal margin concave and U-shaped ventrally, widened towards apex; in lateral view, lateral lobes arched extended caudally. Medioventral process triangular in ventral view. Anal segment (Fig. 4D, F ) long, tubular, symmetrical, apical lobes slightly enlarged, 2.6 times longer than wide in dorsal view; anal style finger-like, not extending beyond anal segment. Gonostyli (Fig. 4D, E, G ) symmetrical in ventral view; in inner lateral view, apical part extended, apical margin round. Aedeagus (Fig. 4H-K ) in total with three processes. Spinose process on right side at apex of periandrium being the longest, slightly curved and apex directed left-dorsocephalad; left side in the middle with a strongly curved spinose process, apex directed ventrocephalad; base of periandrium ventrally with several small teeth. Endosoma slender, structure simple, dorsal margin near the middle with a stout and short spinose process, apex directed dorsocephalad.

Host plant.

Unknown.

Distribution.

China (Guizhou, Yunnan).

Etymology.

The specific name is derived from the Latin campylotropus, meaning curved, referring to the strong curved spinose process on the left side of periandrium.

Remarks.

This new species is similar to K. ussuriensis (Vilbaste, 1968), but differs in: (1) “right” spinose process of periandrium originating from right apex (in K. ussuriensis , “right” spinose process of periandrium originating from ventral apex); (2) left spinose process of periandrium shorter than right one in lateral view (the latter longer than right one); and (3) spinose process of endosoma not reaching apex of endosoma (in K. ussuriensis , spinose process of the endosoma nearly reaching apex of endosoma). It also closely resembles Kuvera kurilensis Anufriev, 1987, however, it differs in that: (1) right spinose process of periandrium longer than left one in lateral view (in K. kurilensis , both processes about equal in length); and (2) spinose process of endosoma not reaching apex of endosoma (in K. kurilensis , spinose process of endosoma nearly reaching apex of endosoma).
