The systematic position of this insect is uncertain, the female being unknown. It 

 differs from the other Gryllodes in the elytra not having a true drum, the membrane 

 not being opaque and parchment-like, and the veins very irregular. Moreover, the 

 infra-genital plate of the male is remarkably large. If the ovipositor of the female is 

 rudimentary, the species should be transferred to the genus Anurogryllus.
