Episymploce sichuanensis sp. nov. Figures 1-4, 5-14

Specimens examined.

Holotype: 1 male, 26°38.48'N, 101°41.62'E, Daheishan, Panzhihua City, Sichuan Province, 6 April 2 014, coll. Ke-Liang Wu et De-Xing Liu. Allotype: 1 female, paratype: 7 males, allotype and paratype were collected together with holotype.

Diagnosis.

This species is similar to E. kunmingi (Bey-Bienko, 1969), but can be distinguished as follows: 1) tegmina and wings reduced, only reaching the second abdominal tergum (T2), while in E. kunmingi (Bey-Bienko, 1969) tegmina and wings reach the apex of abdomen; 2) T1 is unspecialized, whereas T1 is specialized in E. kunmingi (Bey-Bienko, 1969); 3) two inwardly curved bifurcate processes on the hind margin of the supra-anal plate, while in E. kunmingi (Bey-Bienko, 1969) right process bifurcate and left process spine-like.

Description.

Male, pronotum: length × width: 2.8-3.0 × 3.8-4.4 mm; tegmen: 3.5-4.0 mm; overall length (including tegmen): 16.2-17.9 mm. Female, pronotum: length × width: 3.2 × 5.0 mm; tegmen: 3.8 mm; overall length (including tegmen): 14.4 mm.

Small size. Body yellowish orange, head extending somewhat beyond pronotum, ocellus white, interocular space almost equivalent to ocellus space. Pronotum approximate ladder-like, hind margin wide. Tegmina and wings reduced, veins inconspicuous, reaching of T2. Anteroventral margin of front femur Type A3; the first tarsus of the hind leg longer than the sum of the remaining tarsi; tarsal claws symmetrical and unspecialized, arolium and pulvillus present. The T1 unspecialized; T7 specialized with a pair of approximately triangular depressions (Fig. 7); T9 asymmetrical with left side longer than right, apex margin with some small spines (Fig. 9). Male supra-anal plate asymmetrical, hind margin of lamina bilobed, left hind margin has two inwardly curved processes, apex process of which is bifurcate (Figs 6, 8); left side paraproct with three processes and right side with single process. Subgenital plate asymmetrical, basolateral with two processes, left process longer, and apex of right process curved; left of hind margin apparently thicker and covered strongly spinulose, middle hind margin with two spine-like processes reversed and outwardly with long styles (Fig. 10); left aedeagus hook-shaped (Fig. 11). Female is similar to male; abdominal tergum suffused with dark brown, supra-anal plate symmetrical, approximately triangular, apex concave (Fig. 14). Subgenital plate simple and hind margin rounded (Fig. 15).
