Type species: Gryllacris ornata Walker, 1869

Diagnosis. The genus is characterized by its narrow slender appearance with rather long and thin legs and by coloration with distinct brown bands along the cross-veins of both fore and hind wings. On the tegmen, the media divides into MA and MP just before mid-length (in A. guttata sp. nov. and A. kirbyi (Griffini, 1909) or near end of tegmen (in A. ornata cyanea Brunner, 1888 ), while CuA and CuP are both undivided. The genus was so far only known from females in two species and one subspecies. This is the first description of a male of this genus. The male abdominal structures are unique. The divided subgenital plate resembles the situation in Furcilarnaca , however in Australogryllacris it is divided into three lobes nearly from base with the central lobe shorter and all lobes with simple obtuse tip; styli are absent while styli are present in Furcilarnaca . The male ninth abdominal tergite of Australogryllacris is provided with a pair of small protuberances in apical area, while the tenth tergite is provided with a pair of bifold projections that have the dorsal end obtuse and the ventral end terminating into a sharp tooth, while in Furcilarnaca there are one pair of spines each on both ninth and tenth tergite. Characteristic for the genus are also the stout spines on internal ventral margin of the hind femora, especially the two last spines with the penultimate longer than the preceding spines and the last spine even longer and with widened base ( Fig. 44C View FIGURE 44 ).
