A new genus of the subfamily Metrodorinae (Orthoptera: Tetrigidae) from Vietnam

摘要

The monotypie genus Cleostratoides gen. nov. (type species Cleostratoides exoticus sp. nov. from Vietnam) is described in the subfamily Metrodorinae. New genus is closely related to the genera Mazarredia Bolivar, 1887, Xistrella Bolivar, 1909, Pseudoxistrella Liang, 1991, Orthotettixoides Zheng, 1998 and Bermania Storozhenko, 2012, but easily distinguished from all of them by the lateral ocelli situated just under fastigium of vertex and by the antennal sockets placed distinctly above the lower margin of eyes.
