Genus Oxylakis Redtenbacher, 1891

This genus re-described and revised by Ingrisch (1998) and Ingrisch & Tan (2012) is not very uniform, because copulatory structures in one of its representatives ( O. truncatipennis Bol. ) significantly differ from those of the rest congeners. Moreover, in the latter congeners, these structures look more similar to those of the related genus Tabangacris Willemse than to those of O. truncatipennis .
