Pisacha balteiformis sp. nov.

( Figs 83–86 , 100–113 , 118 , 123 )

Description. Length, male (N=2) (including tegmen): 12.8–13.2 mm, length of tegmen: 11.6–12.0 mm; female (N=3) (including tegmen):14.8 –15.2 mm, length of tegmen: 13.4–13.6 mm.

General color fulvous, shiny. Vertex testaceous, median carinae and lateral margins yellowish white. Frons with median area dark brown and light brown, median carina canescent, lateral carinae and margins black, apical angles black, near upper margin with two black spots. Clypeus light brown, median carina yellow, with several oblique short fuscous stripes on each side of median carina. Ocelli red. Eyes black brown with yellow stripes. Antenna tawny, pedicel with sensilla white. Gena light brown with a big black mark on apical angle. Pronotum testaceous, median carinae yellowish white. Mesonotum testaceous at median area, pale yellow laterally, three carinae dark brown. Tegmina transparent, venation dark brown, costal membrane with 9 or 10 transverse veinlets black, widened into short bands.

Vertex 3.2 times wider than long in middle line, anterior margin almost straight, posterior margin obtusely concave ( Figs 83, 85 ). Frons long, 1.4 times longer than wide at widest part, upper margin deeply angularly concave, median carina indistinct, disappeared near apical one-fourth ( Fig. 86 ). Pronotum about 1.6 times longer than vertex in middle line, with narrow median carina; anterior margin obtusely convex, almost reaching the level of upper points of eyes, posterior margin archedly concave ( Fig. 85 ). Mesonotum large, 2.7 times as long as vertex and pronotum combined in middle line, lateral carinae nearly reaching posterior margins. Tegmina transparent, clavus with 8–9 transverse veinlets between the suture and its longitudinal vein, two or three transverse veinlets between two claval veins. Spinal formula of hind leg 11–11–2.

Male terminalia. Anal tube with ventral margin sinuate; 2.4 times longer than widest part in dorsal view, apical margin arched ( Figs 100, 101 ). Anal column very short ( Fig. 101 ). Phallobase with dorso-basal portion expanding apically, apical margin arched, apico-ventral angles sharp ( Fig. 102 ). Dorso-lateral phallobase lobes with apical portion curved upward dorsally and bifurcate, with about 12 small spikes near inner margin of each lobe, apical margin obtuse in lateral view ( Figs 102, 104 ); lateral sides with a pair of relatively long bifurcate processes, upper branches curved near apex, as long as under branches. Ventral phallobase lobe round at median part, apical portion nearly rectangular, apical margin weakly arched (Figs 103,123). Phallus with a pair of short processes directed cephalad, but curved caudad near middle, tips of two processes point to caudad in ventral view ( Figs 103, 104 , 118 , 123 ). Pygofer with posterior margin distinctly convex at middle ( Fig. 100 ).

Female terminalia. Anal tube as long as wide at widest part, apical margin convex ( Figs 105, 106 ). Gonoplac bearing about 9–10 rows of denticles in posterior view ( Fig. 107 ). Anterior connective lamina of gonapophyses VIII with 10 teeth ( Fig. 113 ). Sternum VII with posterior margin nearly straight ( Fig. 109 ).

Type material. Holotype: male, Vietnam, Ninh Binh, Cuc Phuong National Park, N 20º 20' 586'', E 105º 36' 024'', 408m, 21 August 2008, Coll. Zheng G., Sac. PD., Li SQ.

Paratypes: 1 male, 3 females, same data as holotype.

Diagnosis. This species can be distinguished from all other species by the following features 1) the vertex with anterior margin almost straight; 2) tegmina with costal membrane 9 or 10 wide black transverse veinlets; 3) dorsolateral phallobase lobes with each dorsal bifurcate lobe bearing about 12 small spikes near inner margin; lateral apices with a pair of nearly equally bifurcate processes, the branches relatively long, upper branches curved near apex; 4) phallus with a pair of short hooks, tips point to caudad in ventral view.

Etymology. The specific epithet derived from the Latin “ balteiformis ”, referring to costal membrane of tegmina with transverse veinlets widened into bands.
