Pisacha yinggensis sp. nov.

(Figs 38–41, 56–69, 115, 120)

Description. Length, male (N=2) (including tegmen): 11.6–12.0 mm, length of tegmen: 9.9–10.2 mm; female (N=2) (including tegmen):13.2–13.4 mm, length of tegmen: 11.3 mm.

General color dark-brown. Vertex rufous with median carinae pale yellow. Frons yellow, median area with light black marks, lateral area with obscure light black dots, three central carinae and margins black. Clypeus yellow, median carina luminous yellow. Ocelli red. Eyes grey. Antenna tawny, pedicel with sensilla white. Gena yellowish-brown with a black spot on apical angle. Pronotum fuscous, median carinae pale yellow. Mesonotum dark brown medianly, pale fulvous laterally, median carina pale yellow, lateral carina and its outside black. Tegmina transparent, venation dark brown, with a black oblique broad stripe near apical third from costal margin to about middle of tegmen, apex with broadly fuscous stripe.

Vertex 4.0 times wider than long in middle line, each basal lateral angle with a semicircle depression, anterior margin sinuate and emarginate at middle, posterior margin concave (Figs 38, 40). Frons long, 1.5 times longer than wide in mid line, widest at upper margin; upper margin concave, median carina distinct, disappeared near middle (Fig. 41). Pronotum about 1.6 times longer than vertex in middle line; anterior margin obtusely convex, surpassing the level of upper points of eyes; disc wrinkled near anterior margin (Fig. 40). Mesonotum large, 3.0 times as long as vertex and pronotum combined in middle line (Fig. 40). Tegmina transparent, clavus with 7–9 transverse veinlets between the suture and its longitudinal vein, one or no transverse vein between two claval veins. Spinal formula of hind leg 11–9–2.

Male terminalia. Anal tube with ventral margin acutely concave near apical fourth in lateral view (Fig. 56); 2.0 times longer than widest part at middle in dorsal view, apical margin almost straight (Figs 58). Phallobase with dorso-basal processes short (Figs 60, 115), but apical half spilt into two small rectangular lobes. Dorso-lateral phallobase lobes with dorsum bifurcate near apex and membranous, with numerous spikes on the surface before bifurcation; lateral apices forming into a pair of short processes, not bifurcate (Figs 60, 115), lateral sides have a pair of small mammillary processes near apical one-third (Figs 59, 120). Ventral phallobase lobe slightly sclerous and pigmented with apical margin nearly straight (Figs 59, 120). Phallus with a pair of long and thin processes directed cephalad, the processes crossed in ventral view (Figs 59, 120). Pygofer with posterior margin convex near dorsal third (Fig. 56).

Female terminalia. Anal tube nearly peach-shaped in dorsal view, apical margin angular medianlly (Fig. 61). Gonoplac bearing about 10–11 rows of denticles in posterior view (Fig. 66). Anterior connective lamina of gonapophyses VIII with 9 teeth (Fig. 69). Sternum VII with posterior margin convex medianly (Fig. 67).

Type material. Holotype: male, China, Hainan Province, Yinggeling Mountain, N 19º 03' 047'', E 109º 33' 782'', 678m, 21 August 2010, coll. Guo Zheng.

Paratypes: 1 female, same data as holotype; 1 female, China, Hainan Province, Yinggeling Mountain, N 19º 02' 884'', E 109º 53' 529'', 22 August 2010, coll. Guo Zheng; 1 male, China, Hainan Province, Yinggeling Mountain, N 19º 03' 049'', E 109º 33' 751'', 693m, 25 August 2010, coll. Guo Zheng.

Diagnosis. This species looks similar to P. naga by the similar stripes on the tegmina, but can be differentiated from it by the following features: 1) vertex 4.0 times wider than long in middle line, anterior margin sinuate and emarginate at middle, median carina narrow, in P. naga, vertex about 3.5 times wider than long in middle line, anterior margin somewhat convex, median carina relatively wide; 2) pronotum with anterior margin obtusely convex, disc wrinkled near anterior margin; in P. naga, anterior margin strongly convex, without wrinkle; 3) mesonotum with anterior margin relatively convex between eyes, apex reaching to middle of the level of eyes, with wide black stripe only along lateral carina; in P. naga, mesonotum with anterior margin slightly convex between eyes, apex not reaching to one third of the level of eyes, wide black stripe present at transverse carina and lateral carina; 4) frons with median carina black, in P. naga, median carina white.

Etymology. The specific name refers to the locality, Yinggeling Mountain.
