Title: NEW SPECIES AND SUBSPECIES OF GRASSHOPPERS FROM SICHUAN AND YUNNAN, CHINA(ORTHOPTERA: ACRIDOIDEA)
Abstract: In the, present paper, a new species, a new subspecies, and the heretofore undescribed males of two known species of grasshoppers are described. Types are preserved in the Department of Biology, Shaanxi Normal University and Tianjin Natural History Museum.Ptygonotus sichuanensis, sp. nov. (figs. 1-6)This new species is allied to Ptygonotus chinghaiensis Ying, but differs in: (1) frontal ridge with the part above the median ocellus flat and that under the median ocellus slightly concave; (2) lateral carinae of pronotum of male slightly curved in the metazona; (3) furcu-la of male larger; (4) supra-anal plate of male longer than wide.Length of body: 13.8-14; 22 mm. Length of elytra: 3; 3 mm.Length of hind femur: 9-9.5; 11 mm.Holotype cf, allotype , paratype 1, Sichuan (Lixian County). 12. X. 1979, Zheng Zhemin.Ceracris xizangensis brachypennis, subsp. nov. (figs. 7-10)This new subspecies differs from the nominate subspecies Ceracris xizangensis xizangensis Liu in: (1) body smaller; (2) length of the middle segment of antennae about 2-2.5 times its width.Length of body, 16-17 mm; 23-24 mm. Length of elytra: 11-:13 mm; 17 mm. Length of hind femur: 10.5-11mm; 14-14.5 mm.Holotype , allotype , paratypes 1 1 , Yunnan (Baoshan County), 22. VIII. 1979, Liu Shengli.Carsula yunnana Zheng (figs. 11-15)Male: Body slender, elongate. Head strongly elongate, its length about 1.8 times longer than the length of pronotum. Foveolae long and narrow, triangular. Antennae narrow, ensiform, with 21 segments. Eyes long oval, the longitudinal diameter about 1.7 times as long as the horizontal diameter, and slightly longer than the length of subocular suture. Elytra long and narrow, reaching to the four fifths of hind femora or the knee; with about 26-27 regular transverse veinlets in the middle between the radial and median veins. Supra analplate triangular; cercus very long, reaching far behind the top of subgenital plate; su-bgenital plate long conical, apex point. Length of body 42-45 mm; length of head 10-11 mm; length of fastigium of vertex 5-6mm; length of antenna 14-17mm; length of pronotum 5.5-6mm; length of elytra 16-17 mm; length of hind femur 14-15 mm.Distribution: Yunnan (Mengla County).Bannacris punctonotus Zheng (figs. 16-17.)Male: Frons oblique. Vertex narrow, interocular distance extremely narrow. Antennae filiform, extending beyond the middle of hind femora. Eyes oval, the longitudinal diameter about 1.7 times as long as the horizontal diameter, and about 2.5 times as long as the subo-cular suture. Sides of pronotum subparallel, the disc and lateral lobe coarsely punctate and rugose. Elytra long and narrow, slightly reaching beyond tbe top of kind femora. Supra ana-Jplate triangular; cercus long conical, apex point; subgenital plate long conical.Body generally yellow with alternating black stripes. Anterior half of elytra black and the other half yellow. Hind tibia black, near the basal part with a yellow ring.Length of body 18mm; length of elytra 13.5-15mm; length of hind femur 10-11 mm.Distribution: Yunnan (Mengla and Jinghong Counties).
