Examined material. 2 males (holotype and paratype no. 1344466), China: Fujian Province: Jiangle, Longqishan Mt., Lishan, 21.v. 1991, Coll. Shi Yongshan ( IZAS); 2 males, no. 1344467-1344468, China: Fujian: Chongan, Xincun, Sangang, 740 – 900m, 17.v.– 20.v. 1960, Coll. Zhang Yiran & Ma Chenlin ( IZAS); 1 male, no 1344460, China: Fujian Province: Shaowu, 6.viii.– 15.viii. 1946 ( IZAS).

Redescription: Male (holotype). Size distinctly large for typical phaneropterine insects, and distinctly smaller than Paraxantia tibetensis  . Pronotal disk ( Figs. 6View FIGURES 6 – 10, 12View 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 4–7 small spines on ventro-anterior margin; median femur armed with 11–12 small spines on ventro-anterior margin; posterior femur with 26–28 anterior and 2–4 subapical posterior spines on ventral margins. Anterior tibiae with 1 dorsal spine and 1 ventral apical spine on posterior margin, and 4 ventral spines as well as 1 ventral apical spine on anterior margin; median tibiae also only with 1 dorsal spine and 1 ventral apical spine on posterior margin, and 4–5 ventral spines as well as 1 ventral apical spine on anterior margin; posterior tibiae with 25–29 anterior and 25–29 posterior dorsal spines. Tegmen: Wings developed well. Hind wing longer than tegmen. Tegmen extending beyond apex of hind femur. Radial vein of tegmen with two oblique branches reaching posterior margin after radial sector vein. Left stridulatory area (Figs. 28, 30) with posterior margin slightly sharply angular, greatest width between CuM vein and posterior margin large, about 6.6–6.8 millimeters. Stridulatory vein ( Figs. 39, 40View FIGURES 38 – 43, 44View FIGURES 44 – 47) long, with straight stridulatory file composed of about 65 widely arranged teeth, among which most large teeth are of equal size except about 5 basal and 6 apical teeth are gradually becoming smaller towards both ends. Right stridulatory area with distinct but irregular quadrangular mirror (Figs. 31, 33).

Epiproct apically 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. 56View FIGURES 55 – 59). Subgenital plate wider than long, with distinct middle carina; apical margin with a wide triangular notch at middle; styli small, just slightly longer than notch (Fig. 51). Unpaired lower sclerite of phallus with sheet-like upper arm, which slightly longer than conical denticulate lower one, notch between lower lateral arm roundly narrow angular ( Fig. 61View FIGURES 60 – 64).

Female unknown.

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

Measurements of male (mm): Length of body 32.0–33.0; length of pronotum 8.9; length of tegmen 58.5–61.0; width of tegmen 21.0; greatest width of tegminal dorsal part 6.6–6.8; length of hind wing 66.1; length of anterior femur 8.2; length of middle femur 10.9; length of posterior femur 25.0–25.6.

Discussion: Here we remove Xantia sinica Liu, 1993  out of Xantia Brunner  von Wattenwyl and put it into Paraxantia  , mostly due to its different characteristics from the type species of Xantia  , which we mentioned above in the introduction.

Distribution: China: Fujian: Wuyishan Mt.
