This species was long but wrongly known as Gryllus integer. The real G. integer is a western species that is less similar to "Texas integer" (now G. texensis) than is G. rubens. In fact, males of G. texensis and G. rubens are thus far impossible to distinguish morphologically. Some females can be identified by the lengths of their ovipositors (Gray et al. 2001). The calling songs of G. texensis usually have shorter, more regular trills than those of G. rubens, but in places where both species occur, the only way to reliably distinguish their songs is by their pulse rates (after the rates have been adjusted for temperature effects). Even though the two species readily hybridize in the laboratory, they maintain their integrity in the field (Walker 1998, 2000).

Gryllus texensis is a species of cricket described by William H. Cade and Otte in (2000). Cade and Otte clarify that field crickets collected in the Southeastern United States from Florida to Texas identified as Gryllus integer, were in fact misidentified, and should have been classified as G. texensis. Morphologically, Cade and Otte found no differences between G. texensis and Gryllus rubens, however, their call song structure was significantly different (see Gray and Cade (1999)).
