Four new species of Scelimenidae are described. Type specimens are deposited in the Southwest Forestry College. 1 Scelimena spicupennis sp. nov. (Figs.1-3) Diagnosis. Size medium. Vertex narrow, its width narrower than the width of an eye. Middle of fore edge of pronotum with a sharp triangular process; with a pair of oblique keels between shoulders; lateral lobe of poronotum with a straight spine. Elytra long ovoid, top sharp; hind wing extending behind the top of hind femur. Lower margin of midfemur undulate. The first segment of hind tarsus long and wide, its length 1.7 times the length of second and third together. Hind margin of subgenital plate of female with three teeth. This new species is allied to Scelimena guangxiensis Zheng, 1994, but differs in: 1) width of vertex narrower than the width of an eye; 2) pronotum with a pair of oblique keels between shoulders; 3) top of elytra sharp; 4) hind wing extending over the top of hind femur; 5) lower margin of midfemur undulate. ♀. Length of body 16.5mm; length of pronotum 29mm; length of hind femur 10mm; width of shoulders 4mm. Holotype ♀, Jingdong, 1150m, Yunnan, 29 May 2001, collected by OU Xiao-Hong.2 Criotettix yunnanensis sp. nov. (Figs.4-6 )Diagnosis. Size small to medium. Head not raised above poronotum; width of vertex equal to an eye. Median keel of pronotum distinct and complete; in profile, upper margin of pronotum straight; hind process of pronotum longer, reaching the top of hind tibia; posterior angles of lateral lobes sharp angular. Elytra long ovum, top round, its width two times the width of midfemur; hind wing reaching the top of hind process. Lower margin of midfemur straight. The length of subgenital plate of female nearly equal to the width, lateral margins arc, hind margin with three teeth. This new species is related to Criotettix interrupta Zheng et Xie, 2002, but differs in: 1) median keel of pronotum complete; 2)hind process of pronotum longer, reaching the top of hind tibia; 3) width of elytra two times the width of midfemur; 4) hind wing reaching the top of hind process; 5) posterior angles of lateral lobes of pronotum sharp angular; 6) lower margin of midfemur straight. ♀. Length of body 11-15mm. Length of pronotum 16-18mm. Length of hind femur 7-10mm. Holotype ♀, paratype ♀, Yiliang, Yunnan, 11 July 2000, collected by SITU Ying-Xian.3 Criotettix longlingensis sp. nov. (Figs.7-8)Diagnosis. Size small to medium. Head not raised above pronotum; width of vertex 1.3 times the width of an eye; dorsal view, anterior margin not reaching the anterior margins of eyes; in profile, vertex not visible before eyes. Median keel of pronotum complete; lateral keels in prozona slightly contracted backward; with a pair of oblique keels between the shoulders; hind process of pronotum long, extending over the top of hind femur about 5mm. Elytra wide ovum, top round, its width 1.4 times the width of midfemur; hind wing reaching the top of hind process. Lower margin of midfemur undulate. This new species is closely related to Criotettix hainanensis Liang, 2002, but differs from the latter in: 1) dorsal view, anterior margin of vertex not reaching the anterior margin of eyes; 2) inprofile, vertex not visible before eyes; 3) hind process of pronotum long, extending over the top of hind femur about 5mm; 4) with a pair of oblique keels between the shoulders; 5) lower margin of midfemur undulate. ♂. Length of body 11mm. Length of pronotum 15mm. Length of hind femur 61mm. Holotype ♂, Longling, 1520m, Yunnan, 16 Apr. 2002, collected by OU Xiao-Hong.4 Eucriotettix wuliangshanensis sp. nov. (Figs.9-10) Diagnosis. Size small. Head slightly raised above pronotum; vertex narrow, its width narrower than the width of an eye, in profile, vertex not visible before eyes.
