Liu, Chun-Xiang & Kang, Le, 2010, A review of the genus Ruidocollaris Liu (Orthoptera: Tettigoniidae), with description of six new species from China, Zootaxa 2664, pp. 36-60 : 55-56

Ruidocollaris apennis sp. nov.

( Figs. 8 , 17 , 28 , 38 , 45 , 55 , 64 , 93 )

Examined material. Holotype, 1 male, China: Tibet: Linzhi District: Mutuo County: Hanmi, 1900m, 2006. VIII.11, Coll. Liang Hongbin ( IZAS); Paratype, 1 male, same data as in holotype ( IZAS).

Description. Male (holotype). Size median for typical phaneropterines. Pronotal disc with distinct “U”- shaped middle transverse groove lying before middle; anterior margin slightly concave, posterior margin angularly round. Anterior femur armed with 0–2 spines on ventro-anterior margin; median femur armed with 1–3 spines on ventro-anterior margin; posterior femur with 6–8 anterior spines on ventral margins. Posterior tibiae with 11 anterior and 14 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 ( Fig. 93 ).

Male stridulatory vein long, with stridulatory file composed of about 62 densely arranged teeth ( Fig. 28 ). Tenth abdominal tergum with apical margin truncated, epiproct tongue-shaped. Cerci gradually becoming thinner from base to distal third, with apex pointed ( Fig. 55 ). Subgenital plate much longer than wide, apical margin with a sharp triangular notch at middle; styli short fine, as long as one third of subgenital plate ( Fig. 64 ).

Coloration ( Fig. 95 ). Green. Sterna of thorax and of abdomen, cerci, epiproct, paraproct, and male subgenital plate are ferruginous. Compound eyes brown. The first segment of antennae ferruginous, remainder brown or ferruginous. Tegmen green, with numerous dark dots near posterior margin, and many small globes clustered by brown dots in Radial-Medial area.

Female unknown.

Measurements of male (mm). Length of body: 22.0; of pronotum: 7.8; height of paranota: 6.2; length of paranota: 4.2; of tegmen: 47.8; largest width of tegmen: 13.5; length of hind wing: 53.5; of posterior femur: 22.5; of apical style of male: 0.9.

Discussion. The new subspecies resembles Ruidocollaris convexipennis in coloration of abdomen sternum, structure of head, and of pronotum, but distinguished by coloration of head, leg, tegmen and abdominal apex, and shape of tegmen, details of male cerci and subgenital plate.

Etymology. The name shows that the new species resembles R. convexipennis but is distinctly different from the latter.

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