Type material.

Holotype: male, China: Shaanxi, Ningshan County, Huoditang (33°22'N, 108°33'E), 1400-1500m a.s.l., 21.VI.1985, Lan Liu (NWAFU). Paratypes: 1 male, China, Shaanxi, Ningshan County, Huoditang (33°22'N, 108°33'E), 1500m a.s.l., 15.VI.1985, Lan Liu (NWAFU).

Description.

Body length: male 6.7-7.0 mm (n=2), forewing length: male 5.8-6.0 mm (n=2).

Coloration. General color black. Body slightly covered with powdery wax (Fig. 1). Eyes dark brown, ocelli milky white. Antenna and rostrum generally dark brown (Fig. 2). Vertex brown with yellow carinae. Frons dark brown near base with lateral carinae yellow brown to pale brown from latero-basal angles to ends of frontoclypeal suture, clypeus black (Fig. 4). Pronotum shallow brown with darker areas. Mesonotum black with 3 dark brown carinae (Figs 1, 4). Tegmina hyaline with veins yellowish and dark brown granules, pterostigma blackish brown. Forewings with a small irregular, roundish spot on anterior branch of Y-vein (Figs 1, 3). Legs and abdomen yellowish brown.

Head and thorax. Vertex about 3.4 times wider than long. Anterior margin of vertex obscure, with only residual traces, subapical transverse carina parabolic, median carina reaching transverse carinae (Fig. 4). 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. 2). Pronotum tapered with obvious carinae and distinct lateral carinae, strongly incised in middle. Meso-notum with 3 distinct con-colorous carinae (Fig. 4). Tegmina slender, venation pattern: Scp+R usually forked distad of CuA. RP 3-branched, MP with 4 terminals: MP1, MP2, MP3, and MP4, CuA 3-branched, with 11 apical cells (Figs 1, 3). Legs with 3 tibial lateral spines. Hind tibia with 6 apical spines; chaetotaxy of hind tarsi: 7/8, 2nd tarsal segment with 3 platellae.

Male terminalia. Pygofer with a sub-triangular lateral margin; in dorsal view, asymmetrical, with a triangular medioventral process (Figs 5, 6, 14, 15). Anal segment in lateral view slender, straight at basal part; in dorsal view asymmetrical, longer than broad, widening to middle then narrowing, rounded to apex. Anal style sits subapically (Figs 7, 8, 16, 17). Genital styles symmetrical, in lateral view with hook-shaped apex, parallel-sided at basal half (Figs 9, 18). Aedeagus with 3 spinose processes, in ventral view, periandrium narrow near middle, with 2 spinose processes, one comparatively short, arising near base of flagellum, apex curved and directed cephalad. Another process comparatively long, implanted on left side near mid-length of periandrium, S-shaped, curved from left side to right side and then to middle of periandrium, apex curved 120 degrees and directed left-cephalad (Figs 13, 19). In dorsal view, flagellum with a small and short spine extending from middle, reaching apex of the sclerotized portion of flagellum, directed cephalad. Tip of flagellum near base of periandrium (Figs 10, 22). Periandrium asymmetrically widened at base, slightly curving to left. In ventral view, caudal margin of basal segment of periandrium convex, medially with two teeth, lateral apical angle with two teeth near distal portion (Figs 13, 19).

Female terminalia. Unknown.

Etymology.

This species epithet is named after the type locality Huoditang.

Distribution.

China (Shaanxi).

Remarks.

This new species is similar to K. vilbastei but can be separated by the following characteristics: (1) the process implanted on the left side near the mid-length of periandrium ( K. huoditangensis has a long and S-shaped spinose process, curved from the left side to the right side and then to the middle of the periandrium, apex curved 120 degrees and directed left-cephalad, but K. vilbastei has a long spinose process, curved from the left side to the right side, across the shaft sub-apically, apex curved 90 degrees and directed cephalad, not reaching the base of the periandrium); (2) the process extending from the middle of the flagellum ( K. huoditangensis has a small and short spine, reaching the apex of the sclerotized portion of flagellum, but K. vilbastei has a stout and long spine, reaching the middle of the membranous portion of flagellum); and (3) the basal segment of periandrium ( K. huoditangensis asymmetrically widens in dorsal view, slightly curving to the left, caudal margin of the basal segment of the periandrium convex, medially with two teeth, but K. vilbastei symmetrically widens, in ventral view, caudal margin of the basal segment of periandrium convex and serrated).
