( Figs. 4View FIGURES 1 – 5, 9View FIGURES 6 – 10, 14View FIGURES 11 – 15, 19View FIGURES 16 – 25, 24, 34, 35, 42, 46, 49, 53, 58, 63)

Holotype. male, at light, no. 1344462, China: Fujian Province: Jiangle, Longqishan Mt., 11.v. 1991, Coll. Huang Chunmei ( IZAS).

Paratype. 2 males, at light, no. 1344463–1344464, China: Fujian Province: Jiangle, Longqishan Mt., 11.v. 1991, Coll. Yao Jian ( IZAS).

Description: Male (holotype). Size distinctly large for typical phaneropterine and distinctly smaller than Paraxantia tibetensis  . Pronotal disk ( Figs. 10View FIGURES 6 – 10, 14View FIGURES 11 – 15) with deeply engraved first transverse groove, lying at basal fifth, and distinct middle transverse groove, lying slightly before middle; one oblique slightly granular line beginning in middle of each lateral carina, then ending in middle of posterior margin. Anterior femur armed with 7–9 small spines on ventro-anterior margin; median femur armed with 9–11 small spines on ventroanterior margin; posterior femur with 22–26 anterior and 4–6 subapical posterior spines on ventral margins. Anterior tibiae only with 1 dorsal spine and 1 ventral apical spine on posterior margin, and 3 ventral spines as well as 1 ventral apical spine on anterior margin; median tibiae also only with 1 dorsal apical spine and 1 ventral apical spine on posterior margin, and 3–5 ventral spines as well as 1 ventral apical spine on anterior margin; posterior tibiae with 23–25 anterior and 27–30 posterior dorsal spines. Tegmen: Wings developed well. Hind wing longer than tegmen. Tegmen extending beyond apex of hind femur. Radial vein of tegmen with three oblique branches reaching posterior margin after radial sector vein. Left stridulatory area with posterior margin distinctly obtusely angular, greatest width between CuM vein and posterior margin rather small, about 4.8–5.0 millimeters (Fig. 34). Stridulatory vein ( Figs. 42View FIGURES 38 – 43, 46View FIGURES 44 – 47) short, with sinuate stridulatory file composed of about 55 large teeth of approximately equal size, among which 27 teeth at apical half are widely spaced, and remaining 28 teeth are sparsely arranged from middle to base. Right stridulatory area with distinct irregular quadrangular mirror (Fig. 35).

Epiproct sharp triangular. Cerci robust, bifurcate at apical fourth, dorsal one conical, produced inwards and upwards, with apex rounded; ventral one produced and horizontally inwards, abruptly tapering into a long slightly upcurved sharp spine ( Fig. 58View FIGURES 55 – 59). Subgenital plate wider than long, with distinct middle carina; apical margin with a wide triangular notch at middle; styli small, slightly longer than notch (Fig. 53). Unpaired lower sclerite of phallus with upper arm slightly longer than sheet-like lower one, notch between lower lateral sclerite roundly narrow angular with shaping angle of more than 90 degree ( Fig. 63View FIGURES 60 – 64).

Female unknown.

Color: Green, just compound eyes, spines of internal cercal fork and sclerites of genitalia brown.

Measurements of male (mm): Length of body 30.0–32.5; length of pronotum 9.5–11.0; length of tegmen 56.0–58.1; width of tegmen 22.0–23.0; greatest width of tegminal dorsal part 4.8–5.0; length of hind wing 59.9–62.0; length of anterior femur 8.5; length of middle femur 11.9; length of posterior femur 26.5–27.0.

Discussion: P. parasinica  is distinctly distinguished from P. s i n i c a by tegminal R vein possessing 3 branches except Rs, the shape of posterior margin of male stridulatory apparatus, the width of tegminal dorsal part, shape and number of stridulatory teeth of male stridulatory file, and details of male cerci and internal genitalia.

Distribution: China: Fujian: Wuyishan Mt.
