Type material.

Holotype: China • 1 ♂; Qinghai, Gande; 33.96 ° N, 99.93 ° E; 22. VIII. 2008; coll. Xinjiang Li, Jiantao Xiao, Yongchao Zhi; catalogue number 080822015 .

Paratypes: China 8 ♂ 11 ♀, same data as the holotype; catalogue numbers 080822016 – 080822035 .

Etymology.

The species is named after Gande, the type locality.

Diagnosis.

The new species resembles K. wardi in having a small and obtuse furcula in the male epiproct and long cerci that nearly reach the tip of the epiproct, but it can be distinguished by the characters presented in Table 1 .

Description.

Male: body medium-sized (Fig. 1 A, B ). Head shorter than pronotum, and frons slightly oblique in profile. Frontal costa distinct and concave on the level of median ocellus (Fig. 1 C ). Vertical diameter of eyes 1.1 times that of transverse and subocular furrows. Antennae filiform, with 24 segments, slightly longer than head and pronotum combined; length of a middle segment (12 th segment) 2.0 times its width. Pronotum rough, nearly straight on anterior margin, and slightly depressed on median posterior margin. Median carina distinct, slightly cut by last transverse sulci; lateral carinae conspicuous, gradually expanding outward; prozona 2.0 times that of metazona in length. Prosternal process conical, bluntly round at apex. Width of metasternal lobes 1.5 times the length; minimum width of mesosternal interspace 1.6 times the length. Metasternal lobes separated and distinct (Fig. 1 D ). Tegmina and wings absent. Upper carina of hind femur smooth. Hind femur 4.0 times longer than wide. Outer side of upper basal lobe of hind femur distinctly longer than the lower one. Hind tibia with nine spines on inner and eight on outer side; external apical spine absent. Arolium between claws large, widely rounded, nearly reaching the apex of claws. Posterior margin of 10 th abdominal tergite with distinct furcula (Fig. 1 E ). Tympanal organ absent. Epiproct with denticles on the middle of both sides, with a longitudinal groove in basal 1 / 2 and in apical 1 / 4, apically sharp-cornered. Cerci long, conical, and nearly reaching tip of epiproct. Subgenital plate long, sharp-cornered, and protruding backwards. In phallic complex, apical valves of penis slightly longer than cingulum valves; apodemes longer than basal valves of penis, with slightly enlarged and flaky ends; lateral view of basal valves of penis reveals a reniform shape (Fig. 4 A – C ). Bridge of the epiproct straight, wide, and short; ancorae angular, curving inward, with non-sharp tips; anterior projections semicircular, lateral plates straight, and posterior projections conical; lophi large and flaky, extending towards the medial and lower sides, protruding noticeably in the overall plane, with evident tumor protrusions along edge (Fig. 4 D – F ). Female: body robust, larger than male (Fig. 1 G, H ). Eyes small, with vertical diameter equal to transverse diameter, and 0.8 times longer than subocular furrows. Pronotum wider, trapezoidal, last transverse sulci not cutting median carina. Minimum mesosternal interspace width 2.8 times length. Ovipositor margin smooth, with a hook-like apex (Fig. 1 I ). Other characteristics resemble the male.

Coloration.

Body reddish-brown. Eyes yellowish-brown. Antennae light red. Apex and lateral margins of fastigium red. Pronotum lateral carinae red. Upper side of femur reddish-brown. Inner side of hind femur red at the base and the remaining black. Outer side of hind femur reddish-brown (yellow in females) on basal 1 / 4 and black on apical 3 / 4; Ventral face of hind femur red on basal 1 / 2 and black on apical 1 / 2 (Fig. 1 F ). Upper lateral genicular lobe black, other brown. Lower lateral genicular lobe red. Hind tibia black and tarsus brown. Denticles of male epiproct black.

Distribution.

Gande, Qinghai Province, China.
