( Figs. 4 , 13 , 24 , 34 , 42 , 51 , 60 , 70 , 78, 87, 88)

Examined material. Holotype, 1 female, at light, China: Tibet: Linzhi County, Motuo nature reserve, Aniqiao, 300m, 2006. VIII.13, Coll. Liu Chunxiang ( IZAS); Paratype: 23 males, 2 females, same data as in holotype ( IZAS); 5 males, 3 females, at light, China: Tibet: Linzhi County, Mutuo nature reserve, Yarang Village, 760m, 2006. VIII.19, Coll. Baiming ( IZAS); 2 males, China: Tibet, Muotuo, Muotuo city zone, 800m, 2006. VIII.23, Coll. Baiming ( IZAS).

Description. Female (holotype). Size large for typical phaneropterines. Pronotal disc with first transverse groove lying at basal sixth, distinct “U”-shaped middle transverse groove lying at basal third, and third transverse groove lying in middle; anterior margin slightly concave, posterior margin strongly angular round. Anterior femur armed with 3 spines on ventro-anterior margin; median femur armed with 5 spines on ventroanterior margin; posterior femur with 8 anterior spines on ventral margins. Anterior tibiae with 1 anterior and 1–2 posterior spines on dorsal margins; median tibiae with 1 anterior and 5 posterior spines on dorsal margins; posterior tibiae with 22 anterior and 31 posterior dorsal spines. Tegmen: Wings well developed. 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. 87, 88 ).

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 ( Fig. 70 ). Subgenital plate triangular, wider than long; lateral margins approximately straight; apex obtuse (Fig. 78). Ovipositor distinguished, tapering towards apex, one and a half times longer than pronotum, four times much longer than wide, with both margins serrated; apex pointed.

Male stridulatory vein long, with stridulatory file composed of about 100 densely arranged teeth, among which basal four teeth transferred above the basal third part ( Fig. 24 ). Right stridulatory area with distinct irregular triangular mirror ( Fig. 13 ). Tenth abdominal tergum with apical margin truncated, epiproct tongueshaped. Cerci abruptly becoming thinner from base to distal third, apex pointed ( Fig. 51 ). Subgenital plate slightly longer than wide, apical margin with a small triangular notch at middle; styli robust, less than one sixth of subgenital plate ( Fig. 60 ).

Coloration ( Figs. 87, 88 ). Green on the whole view. Tenth abdominal tergum, epiproct, paraproct and cerci yellowish green. Apex of cerci brown. Apex of ovipositor dark brown.

Variation. Rare specimens with some small white round globes clustered by small spots in Radial-Medial area.

Measurements (mm). Length of body: male 31.0, female 30.0; of pronotum: male 9.0, female 10.6; height of paranota: male 7.2; length of paranota: male 5.8; of tegmen: male 54.8, female 56.6; largest width of tegmen: male 14.5, female 17.7; length of hind wing: male 60.5, female 61.5; of posterior femur: male 25.2, female 31.0; of apical style of male: 0.72; length of ovipositor 14.1; largest width of ovipositor 3.2.

Discussion. The new species resembles R. truncatolobata and R. rubescens sp. nov. in large size and shape of whole body, but distinguished from them by the shape of the female ovipositor, less rate between tegminal length and largest width and some details of male subgenital plate.

Etymology. The name suggests that the new species is distinguished from the congeners by the long ovipositor.

Distribution ( Fig. 99 ). China (Tibet).
