The subfamilies Truxalinae and Acridinae are discussed. Acrida maxima Karny 1907 restored to species status from synonymy under Acrida turrita (L. 1758). The subfamily Truxalinae cannot be sustained as a separate taxon and is synonymised under the subfamily Acridinae since on grounds of male epiphallic morphology, femoral stridulatory apparatus and wing venation there is no means of clearly differentiating it from the Acridinae. The decision is supported by examples of functional anatomy from Chromotruxalis Dirsh 1951, Acrida Linnaeus 1758, Truxalis Fabricius 1775, Truxaloides Dirsh 1951, Acridarachnea I. Bolivar 1908, and Chromacrida Dirsh 1952.
