| 摘 要： | 记述采自河南省蚱科二新种,即鸡公山蚱Tetrix jigongshanensis sp. nov.和突背蚱Tetrix glochinota sp. nov..鸡公山蚱近似于凹额蚱Tetrix cavifrontalis Liang, 1998, 主要区别为:1)头顶前缘平直;2)侧面观,头顶与额面隆起呈钝角形;3)侧面观,额面隆在侧单眼前直,不凹陷;4)侧观,前胸背板上缘呈弧形;5)前胸背板前缘钝角形突出;6)后突到达后足股节中部;7)后翅略不到达后突顶端;8)中足股节明显宽于前翅宽.突背蚱近似于仿蚱Tetrix simulans(B.-Bienko, 1929)及云龙蚱Tetrix yunlongensis Zheng et Mao, 2002, 其与二者的区别为:1)头顶前缘平直;2)侧面观,背板上缘前半部球形突出,后半段平直;3)后突到达后足股节顶端.其区别于前者为:1)侧面观,额面隆起在侧单眼前凹陷;2)中足股节宽于前翅等宽.其区别于后者为头顶宽为一眼宽的1.7倍.模式标本保存于陕西师范大学动物研究所昆虫标本室.

| Abstract: | In this paper,two new species of Tetrigidae:Tetrix jigongshanensis sp.nov. and Tetrix glochinota sp.nov.,are described. Type specimens were deposited in the Institute of Zoology,Shaanxi Normal University. 1. Tetrix jigongshanensis sp.nov. This new species is similar to Tetrix cavifrontalis Liang,1998,but differs by the following:1) anterior margin of vertex is straight; 2) in profile,the vertex and frontal ridge forms an obtuse angular; 3) in profile,the frontal ridge straightens before the lateral ocelli; ... |
