摘　　要：蹦蝗属已知有11种,分布在我国的东南部及台湾省。作者在整理标本时发现二新种。现将新种记述如下。 所有模式标本均保存在中国科学院动物研究所。 九连山蹦蝗Sinopodisma jiulianshana,新种 雄:体形中等。头短。复眼间头顶的宽度狭于触角间颜面隆起的宽度。颜面隆起明显,具纵沟或纵沟不明显,两侧缘几乎平行。颜面侧隆线明显。触角丝状,超过前胸背板的后缘。复眼卵形,垂直直径为水平直径的1.2—1.3倍,为眼下沟长的1.6—1.8倍。前胸背板圆柱状,具点刻;中隆线低、细,被3条横沟所割断;沟前区的长度为沟后区长的1.8—2.0倍;前缘微弧形,后缘具小的三角形凹口;侧片长大于高。The present paper describes two new species of Sinopodisma Chang from China. All type specimens preserved in the Institute of Zoology, Academia Sinica. Sinopodisma jiulianshana, sp. nov. Male: Size medium. Antennae slender, extending over the posterior margin of pronotum. Eyes oval, its vertical diameter 1.6-1.8 times the distance of snbocular suture. Pronotum cylindrical, median keel low, weak, cut by three transverse culci, the length of prozona about 1.8-2.0 times the length of meta-zona, posterior margin slightly emarginated. Prosternal spine conical, blunt rounded at apex. Mesosternal lobes as broad as length, the length of interspace between mesosternal lobes 1.3-2.0 times the minimum width. Elytra narrow, its length about 2.5-2.9 times the broad, extending slightly beyond the posterior margin of first abdominal segment. Tympanum developed. Hind tibia without outer apical spine. The forms of analplate and cerci as fig. 2,3. Body brownish. Behind the eyes, the sides of pronotum, mesonotum, meta-notum, 1-5 abdominal segments and the posterior margin of elytra with black bands. Elytra dark brown. The inner and outer sides of hind femora yellowish green or olive green. Female:Body robust, larger than male. Subgenital plate longer than broad, with acut triangular projection at middle of posterior margin. Holotype (?), Ailotype(?), Jiulianshan. Jiangxi, 30. Ⅸ. 1979, collected by Yu Peiyu. This new species is closely related to S. lofaoshana (Tinkham), but differs by the form of cerci, the apex of supraanal plate not pointed, elytra shorter, not reaching the posterior margin of 2nd abdominal segment. Sinopodisma houshana, sp. nov. Male: Size medium. Head short. Antennae extending over the posterior margin of pronotum obviously. Eyes oval, the vertical diameter 1.7-2.0 times the distance of subocular suture. Pronotum cylindrical, median keel low, weak, cut by hind transverse culcus obviously, the length of prozona 1.7-2.0 times the length of metazona, posterior margin cmarginal or not. Elytra not reaching slightl
