Type species: Gryllacris maculicollis Serville, 1831

Discussion. Already Karny (1937) divided the Gryllacris into four groups: fuscifrons group, nigrilabris group, signifera group, and voluptaria group that included many but not all species of the genus. Two more of his genera, Pardogryllacris Karny (1937) and Gigantogryllacris Karny (1937) can also be regarded as subgroups of Gryllacris . Pardogryllacris differs from Gryllacris s. str. mainly by the spotted pattern of the fore wings. The males of this genus belong to the species with the most strongly modified ninth abdominal tergite within Gryllacris . As I studied only few species of it, I reduce it only to subgenus level but future studies may proof that they represent only a subgroup of Gryllacris s. str. Gigantogryllacris is also reduced to subgeneric level. It comprises the largest species of the genus but not all species included are really large. In general morphology and male and female appendages there is a transition to the fuscifrons group of Gryllacris with only a minor difference in the shape of the female seventh abdominal sternite. If this difference is constant has to be proven or falsified by future research.
