Ruidocollaris ferruginescens sp. nov.

(Figs. 19, 20, 30, 47, 48, 57, 66, 95, 99)

Examined material. Holotype, male, China: Guangxi Prov.: Jinxiu, Linhai Hotel, 1000m, 2000. VII.2, Coll. Yao Jian ( IZAS); Paratype, China: Guangxi Prov.: Jinxiu, 2 males, Linhai Hotel, 1000m, 2000. VII.2, Coll. Li Wenzhu ( IZAS); 1 male, Shengtangshan Mt., 900–1900m, 2000. VI.29, Chen Jun ( IZAS).

Description. Male (holotype). Size median for typical phaneropterines. Pronotal disc with distinct “U”- shaped middle transverse groove lying slightly before middle, and other transverse groove indistinct; anterior margin slightly concave, posterior margin widely round; paranota about as long as high, ventral margin approximately straight, ventrally expanding backwards, humeral notch distinct. Anterior femur armed with 5– 6 spines on ventro-anterior margin; median femur armed with 4–5 spines on ventro-anterior margin; posterior femur with 5–6 subapical anterior spines on ventral margins. Anterior tibiae with 1 posterior spines on dorsal margin; median tibiae with 4–6 posterior spines on dorsal margins; posterior tibiae with 19 anterior and 28 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.

Male stridulatory vein long, with stridulatory file composed of about 76 densely arranged teeth ( Fig. 30 ). Right stridulatory area with distinct irregular triangular mirror (Fig. 20). Tenth abdominal tergum with apical margin emarginated. Epiproct wide tongue-shaped ( Figs. 47 , 48). Cerci conical, incurved, apex with an obtuse tooth on interior margin ( Fig. 57 ). Subgenital plate much longer than wide, middle of interior margin of wide triangular apical notch with a tooth; styli robust, as long as one third subgenital plate ( Fig. 66 ).

Female unknown.

Coloration ( Fig. 95 ). Green. Face, scape and peduncle of antennae, 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. The first segment of flagellum ferruginous, remainder brown or ferruginous. Tegmen green, with numerous dark dots near posterior margin.

Measurements of male (mm). Length of body 31.5; of pronotum 8.4; height of paranota 6.1; length of paranota 4.8; of tegmen 50.5; largest width of tegmen 14.0; length of hind wing 54.2; of posterior femur 29.5; of apical style 1.1.

Discussion. The new species resembles R. convexipennis and R. apennis sp. nov. in the coloration of body except of wing, but distinguished from them by the shape of head, pronotum, the shape and color of wing, and details of male abdominal apex. It also resembles R. latilobalis sp. nov. in the shape of head and pronotal disc, but differs by the shape of pronotal lateral lobe, the shape and color of wing, and details of male abdominal apex.

Etymology. The name is composed of the word “ ferrugin- ” and its suffix, refers that the new species possesses particular ventral coloration.

Distribution ( Fig. 99 ). China (Guangxi).
