Etymology: the specific name cruscastaneus is derived from the Latin crus =leg and castaneus =brown, and refers to the light brown color of these cricket’s legs.

Diagnosis: combination of the following characteristics: general morphology of the pseudepiphallic paramere 1 ( Figs 56–60 ); pseudepiphallic apex acuminate and curved inward ( Figs 56, 58, 60 ); pseudepiphallic arms do not converging anteriorly ( Fig 56 ); legs I, II and III light brown ( Figs 47–52 ).
