Description. Male (holotype). Size large for typical phaneropterines. Pronotal disc with distinct “U”- shaped middle transverse groove lying slightly before middle; anterior margin slightly concave, posterior margin extending backward, with approximately angularly round center. Anterior femur armed with 4 spines on ventro-anterior margin; median femur armed with 7 spines on ventro-anterior margin; posterior femur with 4–5 anterior and 0–1 spines on ventral margins. Median tibiae with 5 posterior spines on dorsal margins; posterior tibiae with 21 anterior and 23 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 other oblique branches reaching posterior margin after radial sector vein (Figs. 90, 91).
Male stridulatory vein long, with stridulatory file composed of about 96 densely arranged teeth (Fig. 26). Tenth abdominal tergum with apical margin truncated, epiproct tongue-shaped. Cerci gradually becoming thinner from base to middle, with apex pointed (Fig. 53). Subgenital plate much wider than long, apical margin with a small sharp triangular notch at middle; styli short fine, less than one fifth of subgenital plate (Fig. 62).
Female tenth abdominal tergum not produced, with dorso-medial groove; posterior margin obtusely emarginated. Epiproct wider than long, triangular. Cerci conical, slightly curved, gradually tapering in pointed apex. Ovipositor slightly shorter than pronotum, gradually upcurved, with regularly arranged rows of granulations on lateral surface; apical part tapering, with obliquely truncated ventral margin, and both margin serrate; apex pointed (Fig. 72). Subgenital plate triangular, wider than long; lateral margins approximately straight; apex obtuse (Fig. 80).
Coloration. Green on whole view. Antennae with yellowish base, distally blackening, with 4–5 yellowish rings. Face, coxa and trochanter of leg, sterna of thorax and of abdomen, cerci, epiproct, paraproct, and ninth and tenth abdominal tergite are ferruginous. Compound eyes brown. Tegmen green, with about 6 blackish marks situated along the posterior margin and formed by darkened tips of adjoining cross veins; similar series of marks sometimes present along median area of tegmen; stridulatory organ of male often with blackish marks near the ends of the thick diagonal veins.
Measurements (mm). Length of body: male 23.0, female 28.0; of pronotum: male 7.5, female 7.8; height of paranota: male 5.7; length of paranota: male 4.1; of tegmen: male 46.0, female 47.8; largest width of tegmen: male 7.6, female 13.6; length of hind wing: male 52.2, female 53.5; of posterior femur: male 22.5, female 23.5; of apical style of male: 0.8; length of ovipositor 8.0; largest width of ovipositor 3.0.
Discussion. The new species resembles R. convexipennis in coloration, tegminal shape, and structure of head, of pronotum, but it distinctly distinguished from the latter by the much larger size, lateral margin of the notch of male subgenital plate with a middle tooth, and female ovipositor with sharply obliquely truncated apical margins.
Etymology. The name shows that the new species most resembles R. convexipennis but can not be identified as the latter.
Distribution (Fig. 97). China (Tibet).
