Abstract

Descriptions of seven new, short-winged Australian Agraeciine genera are presented with details of distribution, calling songs and karyotypes of several species.

Included in the new subtribe are the following: Australiagraecia Rentz, Su and Ueshima Gen. et sp. nov. with the species A. spina Rentz, Su and Ueshima Gen. et sp. nov. (type species); A. minuta Rentz, Su and Ueshima Gen. et sp. nov.; A. helleri Rentz, Su and Ueshima Gen. et sp. nov.; A. torndirrupa Rentz, Su and Ueshima Gen. et sp. nov.; A. tagera Rentz, Su and Ueshima Gen. et sp. nov.; A. gladiator Rentz, Su and Ueshima Gen. et sp. nov.; A. curvata Rentz, Su and Ueshima Gen. et sp. nov.

Latitatagraecia Rentz, Su and Ueshima Gen. nov.; L. kalamaya Rentz, Su and Ueshima Gen. et sp. nov. (type species); L. vulgivaga Rentz, Su and Ueshima Gen. et sp. nov. The following are placed in the subtribe Agraeciina Redtenbacher 1891: Cooloolagraecia Rentz, Su and Ueshima Gen. nov.; C. wallum Rentz, Su and Ueshima Gen. et sp. nov. (type species); C. gubbi Rentz, Su and Ueshima Gen. et sp. nov. Kokominiagraecia Rentz, Su and Ueshima Gen. nov.; K. dicra Rentz, Su and Ueshima Gen. et sp. nov. (type species).
