A revision of the South African katydid genus Austrodontura Fontana & Buzzetti (Orthoptera: Tettigoniidae: Phaneropterinae)

摘要

The South African genus Austrodontura Fontana & Buzzetti of brachypterous katydids is revised. A. capensis (Walker, 1869) is redescribed and A. castletoni sp. n. from the Eastern Cape Province is described, A. raggei Fontanta & Buzzetti is considereda junior synonym of A. capensis. Acoustic behavior of A. castletoni is described. Wing reduction in the leaf katydids (Phaneropterinae) is a common trait that appears to have evolved independently multiple times within the Tettigoniidae (Naskrecki et ah,in prep.)
