Type material.

Holotype: male. China: Zhejiang, Anji County, Longwangshan (30°23'N, 119°23'E), 1000-1200m a.s.l., 6/8.VIII.2000, Wu Dai & Cong Wei (NWAFU). Paratypes: 2 males, same data as holotype.

Description.

Body length: male 5.1-5.6 mm (n=3), forewing length: male 5.2-5.3 (n=3).

Coloration. General color black. Body slightly covered with powdery wax (Fig. 23). Eyes dark brown, ocelli white. Antenna and rostrum generally dark brown (Fig. 24). Vertex brown, apical margin of vertex and surroundings yellow (Fig. 26). Frons dark brown, apical and lateral margins of frons yellowish brown, adjacent area of middle carinae near middle to frontoclypeal suture dark, and V-shaped, frontoclypeal suture and clypeus blackish brown, median carina yellowish (Fig. 24). Pronotum dark brown with yellowish areas. Mesonotum black with 3 dark brown carinae (Figs 23, 26). Tegmina hyaline with veins brown and yellow brown granules, pterostigma blackish brown. Forewings with a small irregular, roundish spot on anterior branch of Y-vein (Figs 23, 25). Legs brown, abdomen dark brown.

Head and thorax. Vertex about 3.8 times wider than long. Lateral and transvers carinae slightly elevated, sub-apical transverse carina parabolic, median carina reaching transverse carinae (Fig. 26). Frons slightly swollen, median carina only distinct on basal portion, frontoclypeal suture strongly arcuate. Middle ocelli present. Clypeus swollen, with a visible median carina. Rostrum, just reaching hind coxae (Fig. 24). Pronotum tapered with obvious carinae and distinct lateral carinae, strongly incised in middle. Mesonotum with 3 distinct con-colorous carinae (Figs 23, 26). Tegmina slender, venation pattern: Scp+R usually forked distad of CuA. RP 3-branched, MP with 5 terminals: MP11, MP12, MP2, MP3, and MP4, CuA 2-branched, with 10 apical cells (Figs 23, 25). Legs with 3 tibial lateral spines. Hind tibia 6 apical spines; chaetotaxy of hind tarsi: 7/8, 2nd tarsal segment with 4 platellae.

Male terminalia. Pygofer with lateral margin sub-triangular in outline; in dorsal view, asymmetrical, wider than long, with a triangular medioventral process (Figs 27, 28, 36, 37). Anal segment in lateral view slender, widening in the middle and then narrowing, rounded at the apex; in dorsal view asymmetrical, longer than broad, narrow near base, expanded sub-apically (Figs 29, 30, 38, 39). Genital styles symmetrical, in lateral view with hook-shaped apex, inner margin deeply concave but outer margin rounded (Figs 31, 40). Aedeagus with 3 spinose processes, in ventral view, periandrium narrow near middle, with 2 spinose processes, the length of shorter spinose process about two-thirds of the longer spinose process. The longer one implanted on the left side near the mid-length of periandrium, gently curved from left to right side, apex curved over shaft and towards the right side. The shorter one arising near base of flagellum, touching shaft apically, apex curved and directed ventrally (Figs 32, 41). In dorsal view, flagellum with a stout and long spine extending nearly one-third the length of flagellum, the length of this spine more than two-thirds that of the longest spinose process, directed cephalad. The tip of flagellum reaches the base of the periandrium (Figs 35, 44). Periandrium asymmetrically widens at base, slightly curving to left. In ventral view, caudal margin of the basal segment of the periandrium convex, medially with a tooth, lateral apical angle with two teeth near the distal portion (Figs 32, 41).

Female terminalia. Unknown.

Etymology.

This species epithet is named after the type locality Longwangshan.

Distribution.

China (Zhejiang).

Remarks.

This new species is similar to K. flaviceps , but can be separated by the following characteristics: (1) in dorsal view, the process implanted on the left side near the mid-length of the periandrium ( K. longwangshanensis has a long spine, gently curved from left side to right side, apex curved over the shaft and to the right side, but K. flaviceps has a long spine, gently curved from the left to right side, apex not reaching the right lateral margin of the periandrium); (2) the process arising near the base of the flagellum ( K. longwangshanensis has a shorter spine, touching the shaft apically, apex strongly curved mesad and directed ventrally, but K. flaviceps has a spine not touching the shaft apically, apex slightly curved and directed cephalad); and (3) the process of the flagellum ( K. longwangshanensis has a stout and long spine extending nearly one-third the length of flagellum, the length of this spine is more than two-thirds of the longest spinose process, directed cephalad; but K. flaviceps has a thinner and shorter spine extending from the middle of flagellum, this spine is about half the length of the spinose process).
