TWO NEW SPECIES OF THE GENUS XENOCATANTOPS (ORTHOPTERA,ACRIDOIDEA,CATANTOPIDAE) FROM CHINA

记述了采自中国台湾斑腿蝗科外斑腿蝗属Xenocatantops Dirsh，1953的2新种。台湾外斑腿蝗X．taiwanensis sp．nov．近似Xenocatantops sauteri（Ramme，1941），区别特征为前翅较长，超过后足股节中部，到达肛上板的中点；颜面隆起具纵沟，两侧近平行，中部微缩狭；前胸腹板突圆柱形，端圆形。长翅外斑腿蝗X．longipennis sp.nov.近似Xenocatantops luteitibia Zheng et Jiang，2002，区别特征为后足股节粗壮，长为最宽处的3．7倍；触角中段一节的长为宽的1．1～1．3倍；前胸背板缺小黑点。并附外斑腿蝗属中国已知种的检索表。模式标本保存于国立自然科学博物馆，台中。

Two new species i. e. Xenocatantops taiwanensis sp. nov. and X. longipennis sp. nov. from Taiwan, China are described inthis paper. X. taiwanensis sp. nov. is similar to X. sauteri （Ramme, 1941）, but differs from latter： 1） tegmina longer, extending over the midpoint of hind femur distinctly, reaching to the midpoint of epiproct; 2） frontal ridge with longitudinal sulcus, both sides almost parallel, narrowed slimy in the middle; 3） prostemal process cylindrical, apex rounded. X. longipennis sp. nov. is allied to X. luteitibia Zheng et Jiang, 2002, but differs in hind femur robust, the length about 3.7 times maximum width; length of a segment in the middle of antennae 1.1-1.4 times width; head and pronotum without small black spots. A key to known species of the genus Xenocatantops from China is given. Type specimens are deposited in National Museum of Natural Science （NMNH）, Taichung, Taiwan, China.
