description: Caliscelis rhabdocladis, sp. nov.   
Figs 7–12, 35–44  
 Description. Length, male: 4.0– 4.4 mm, length of tegmen: 2.3–2.4mm; female: 5.8–6.0mm, length of tegmen: 2.4–2.6mm.   
Male. Body dark brown, with pale brown maculae (Fig. 7). Vertex brown, suffused with blackish brown (Fig. 7). Eyes blackish brown. Frons brown, suffused with dark brown spots; clypeus dark brown (Fig. 8). Rostrum pale brown. Pronotum white and mesoscutellum brown with dark brown spots (Fig. 7). Tegmina dark brown with white stripe (Fig. 7). Legs reddish brown, fore femora and tibia blackish brown, hind femora with black stripe (Fig. 9). Dorsum of the abdomen brown with pale brown stripe and dark brown spots, and venter blackish brown with yellow stripe (Figs 7, 9).  
Female. Body pale brown with brown maculae, with pale brown stripe in the middle of dorsum (Figs 10–12).  
Vertex subquadrilateral, with anterior margin somewhat convex and posterior margin nearly truncate, 3.3× wider at apex than length in middle line (Fig. 7), disc evidently depressed. Frons not elevated with lateral carinae present only near apical part; disc finely granulose, anterior margin evidently concave, 1.1× wider at widest part than at base, midlength 1.3× longer than greatest width (Fig. 8). Frontoclypeal suture nearly straight. Clypeus smooth, without carina, disc evidently elevated (Fig. 8). Pronotum wide, medial carina absent. Mesoscutellum broad and short; disc evidently elevated, with lateral carinae, which curves inwards as in Figure 8; 2.1 × wider at widest part than medial length (Fig. 8). Tegmina short, subquadrilateral, with pits on disc; 1.3× longer than widest part; one clubbed stripe from base to inner apex (Fig. 8). Fore femora and tibia distinctly foliately dilated (Figs 9, 35); hind tibia with a lateral tooth near apex. Spinal formula of hind leg 6–2–2.  
 Male genitalia: Anal segment in dorsal view elliptical, apical margin distinctly convex with angles obtuse, evidently longer than medial width, anal foramen near middle (Fig. 37). In lateral view, anal segment relatively small, latero-apical angles downcurved, tapering directed caudad, ventral margin nearly straight (Fig. 36). In lateral view, pygofer with laterodorsal angles slightly prominent, lateral margin strongly sinuate, dorsocaudal angle shallowly produced and narrowed near middle (Fig. 37). Phallus tubular in profile, asymmetrical, connective rod-like and with one short spiniform process near base and one short spiniform process near apex (Figs 38–39). Aedeagus terminating in lobes directed caudad (Figs 38–39), dorsal margin serrulate as Figs 39. Genital styles moderately long, nearly rectangular, 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. 36).   
 Female genitalia: Anal segment in dorsal view nearly triangular, apical margin convex with angles rounded, lateral margin smoothly, length in middle longer than widest part, anal foramen in basal half (Fig. 40). Ovipositor with first valvulae narrow with 3 finger-like processes at apex, first valvifer nearly square (Fig. 41); second valvulae with two laminae in apical half united in basal half, the lamina with a row of teeth (about 11) on dorsal margin, proximally, the valvulae with pair of short processes (Figs 42, 43); third valvulae stout, flat medially, nearly rectangular, dorsal part with short notch (Fig. 44). Pregenital sternite with apical margin nearly straight.   
 Material examined   
 Holotype: ♂, China: Beijing, Langfang, 10 Sept. 2010, coll. P. Wang. Paratypes: 1♂ 1♀, same data as holotype; 4♂ 3♀, Beijing, Langfang, 13 June 2011, coll. P. Wang; 1♂, Beijing, Pinggu, 15 July 1981, coll. X. L. Wang. (NWAFU).   
 Distribution. China (Beijing).   
 Remarks. This species resembles C. affinis but it can be distinguished by: 1) frons without median carina, present in C. affinis; 2) mesoscutellum with lateral carinae, absent in C. affinis; 3) fore femora and tibiae distinctly foliately dilated, while in C. affinis, fore femora and tibiae are more or less expanded.   
 Etymology. The specific epithet “rhabdocladus” is derived from Latin, referring to the rod-like connective of the phallus.   
 Notes. This species usually likes to crawl slowly, or jump quickly on reeds, it rarely flies (P. Wang, pers. obs.).
