Caliscelis triplicata , sp. nov.

Figs 13–18, 45–56

Description. Length, male: 4.2–4.3mm, length of tegmen: 2.2mm; female: 5.5–5.7 mm, length of tegmen: 2.3 mm Male. Body brown, with pale brown maculae and dark brown spots ( Fig. 13). Vertex and frons brown, suffused with blackish brown spots ( Figs 13, 14). Eyes blackish brown. Clypeus brown, with dark brown spots ( Fig. 14). Rostrum pale brown. Pronotum and mesoscutellum brown, with dark brown spots and pale brown stripes ( Fig. 13). Tegmina brown, with dark brown spots and white stripe ( Fig. 13). Legs reddish brown, fore femora and tibia blackish brown, hind femora with black stripe ( Figs 13, 15). Dorsum of the abdomen brown with pale brown stripe and dark brown spots, and venter blackish brown with yellow stripe ( Figs 13, 15).

Female. Body pale brown with brown maculae, with pale brown stripe in the middle of dorsum ( Figs 16–18).

Vertex subquadrilateral, with anterior margin somewhat convex and posterior margin nearly truncate, 3.2× wider at apex than length in middle line ( Fig. 13), disc evidently depressed. Frons not elevated, disc finely granulose, anterior margin evidently concave; frons with median carina and inversed U-shaped lateral carina, 0.9× wider at widest part than at base, midlength 1.4× longer than greatest width ( Fig. 14). Frontoclypeal suture nearly straight. Clypeus smooth, without carina, disc evidently elevated. Pronotum wide, medial carina absent. Mesoscutellum broad and short; disc elevated, with lateral carinae, which curved inwards as Fig. 18; 2.2 × wider at widest part than medial length. Tegmina short and subquadrilateral, with pits on disc, 1.3× longer than widest part, one clubbed stripe from base to inner apex ( Fig. 13). Fore, middle and hind femora and tibiae more or less foliately dilated ( Figs 45–47); Hind tibia with lateral tooth near apex. Spinal formula of hind leg 6–2–2.

Male genitalia: Anal segment in dorsal view nearly square, apical margin distinctly convex with angles obtuse, evidently longer than medial width, anal foramen near middle ( Fig. 49). In lateral view, anal segment relatively small, tapering caudad, ventral margin nearly straight ( Fig. 48). In lateral view, pygofer with laterodorsal angles slightly prominent, lateral margin strongly sinuate, dorsocaudal angle shallowly produced and strongly produced near middle, then narrowed ( Fig. 48). Phallus tubular in profile, symmetrical, with two short spiniform processes. Aedeagus terminating in lobes directed caudad ( Figs 50–51), ventral margin serrated as in Fig. 50. Genital styles narrow and long, about as wide near base as apex; basal margin evidently convex, ventral margin nearly straight; apical margin more or less rounded; dorsal margin near middle produced dorsad in one large and long finger-like lobe ( Fig. 48).

Female genitalia: Anal segment in dorsal view nearly elliptical, apical margin strongly convex with angles rounded, lateral margin smoothly but obviously curved, much wider with middle as widest part, anal foramen in basal half ( Fig. 52). In lateral view, anal segment relatively narrow, latero-apical angles decurved and acute, ventral margin distinctly curved. Ovipositor with first valvulae narrow and curved dorsally, with three finger-like processes, first valvifer nearly rectangular ( Fig. 53); second valvulae with two laminae in apical half united in basal half, the lamina with row of teeth (about 9) on dorsal margin, proximally, the valvulae with pair of short processes dorsally ( Figs 54–55); third valvulae flat and stout, nearly rectangular, dorsal part with narrow notch ( Fig. 56). Pregenital sternite with apical margin nearly straight.

Material examined. Holotype: ♂, China: Xinjiang, Changji , 27 Jun. 1987, coll. M. Wang. Paratypes: 1♂, Xinjiang, Changji , 19 June 1984, collector unknown ; 1♀, Xinjiang, Changji , 26 June 1987, coll. M. Wang ; 1♀, Xinjiang, Shihezi , 14 July 1979, coll. T. Chen ; 1♀, Xinjiang, Manasi , 1984, coll. J. Z. Yang. ( NWAFU) .

Distribution. China (Xinjiang).

Remarks. This species resembles C. chinensis , but differs in the following characteristics: 1) fore, middle and hind femora and tibiae are all expanded foliately, while in C. chinensis , only the fore femora and tibia are dilated; 2) tegmina with one pale stripe along the posterior margin, absent in C. chinensis ; 3) pronotum and mesoscutellum without median carina, which is present in C. chinensis .

Etymology. The specific epithet is derived from the Latin word triplicatus, referring to the foliately expanded fore, middle and hind femora and tibiae.
