中文摘要：

记述了中国台湾小车蝗属Oedaleus Fieber,1853的3新种。新种夏氏小车蝗Oedaleus xiai sp.nov.前翅短,刚到达后足股节顶端,可同本属所有已知种相区别。新种高雄小车蝗Oedaleus kaohsiungensis sp.nov.与台湾小车蝗Oe.formosana（Shiraki,1910）近似,不同之处为后足股节内侧具黑色斑纹和后足胫节黄褐色,非红色。新种南投小车蝗Oedaleus nantouensis sp.nov.与台湾小车蝗Oe.formosana（Shiraki,1910）近似,不同之处为复眼较大,纵径等于眼下沟的长度;中胸腹板中隔很宽,最小宽度为长的1.8倍。新种南投小车蝗Oedaleus nantouensis sp.nov.与高雄小车蝗Oedaleus kaohsiungensis sp.nov.也近似,不同之处为后足股节下缘红色,后足胫节红色。列出了产于中国的小车蝗属13个种的检索表。模式标本存于自然科学博物馆,台中,台湾,中国。

英文摘要：

Three new species of the genus Oedaleus Fieber,1853 from Taiwan,China are described in this paper.Oedaleus xiai sp. nov. differs from all known species of the genus by the tegmina shorter,just reaching the end of hind femur. Oedaleus kaohsiungensis sp. nov. is similar to Oe. formosana（ Shiraki,1910）,but differs from the latter by the hind femur with black band on inner side and hind tibia yellowish brown,not red. Oedaleus nantouensis sp. nov. is similar to Oe. formosana（ Shiraki,1910）,but differs from the latter by eye larger,vertical diameter almost equal to subocular furrow and interspace of mesosternum wider,minimum width 1. 8 times length. Oedaleus nantouensis sp. nov. is also allied to Oedaleus kaohsiungensis sp. nov.,but differs from the latter by hind femur red on lower side and hind tibia red. A key to all 13 known species of the genus from China is provided. Type specimens are deposited in the National Museum of Natural Science,Taichung,Taiwan,China.
