【Abstract】 The present paper deals with three new species of Catantopidae. The materials were collected from Sichuan province. Type specimens are deposited in the Institute of Zoology,Shaanxi Normal University.Caryanda gulinensis sp. nov. (figs. 1￣5)This new species resembles Caryanda prominemargina Xie et Zheng, but differs from the latter in the following characters:1) the width of interocular distance larger than the width of frontal ridge between the antennae about 3 times ; 2) hind margin of pronotum with shallow concave; 3) prosternal spine conical ; 4) interspace of mesosternal lobes nearly square; 5) the top of median keel of hind femur spine like.Length of body: 28 mm; length of pronotum: 5 mm; length of elytra: 5 mm;length of hind femur: 15 mm.Holotype , Sichuan: Gulin, 1100￣1300 m. 23. VII. 1993, collected by Chen Jun.Sinopodisma sunzishanensis sp. nov. (figs. 6￣12)This new species is allied to Sinopodisma kellogii(Chang)and Sinopodisma quizhouensis Zheng. It differs from both by: 1) interocular distance as wide as or slightly narrower than frontal ridge between antennae;2) length of middle segment larger than width about 3￣4times;3)the width of the middle of cercus as long as the apex,the top round;4)hind femur yellow green.It differs from the former by:1) the length of prozona longer than metazona about 1. 55-1. 75 times;2)the last abdominal tergite of male with furcula.It differs from the latter by the elytra not reaching the hind margin of the first tergite.Length of body:16￣19 mm;22￣27 mm.Length of pronotum:3. 5￣4 mm;5￣ 6 mm. Length of elytra:2. 5￣3 mm;3. 5￣4 mm. Length of hind femur:10￣11mm;13￣15 mm.Holotype,allotype,Sichuan: Gulin (Sunzishan), 23. VII.1993, 1100-1300 m,collected by Chen Jun; paratypes 17,11, Sichuan: Gulin (Sunzishan),20￣23.VII. 1993,1100￣1750 m, collected by Chen Jun and Shi Fumin.Pseudoptygonotus jinshaensis sp. nov. (figs. 13￣19)This new species is allied to Pseudoptygonotus kunmingensis Cheng, but differs in: 1)metazona of pronotum withest lateral keels; 2) anal plate of male narrow and long,triangular ; 3) subgenital plate of male narrow, apex sharp round ; 4) elytra black, anal area yellow brown ; 5) basal part of inner side of hind femur orange yellow and terminal part orange red; 6) tip of ovipositor blunt, lower valve without teeth.Length of body: 14. 5￣16 mm ; 20￣22 mm. Length of pronotum: 3. 5￣4 mm; 4. 5￣5 mm. Length of elytra: 3 mm; 3￣5 mm. Length of hind femur: 9￣10 mm ; 10. 5￣12 mm.Holotype , allotype , Sichuan: Huili, 11. VIII. 1992, collected by Chen Jun;paratypes 2 as Holotype; 1 ,Sichuan: Huili, 11. VIII. 1992, collected by Shi Fumin, 1, Sichuan: Panzhihua, 13. VIII. 1992, collected by Shi Fumin.更多还原
