Studies in Australian Tettigoniidae: Australian Pseudophylline katydids (Tettigoniidae; Pseudophyllinae; Phyllomimini)

The genus Acauloplacella Karny is recorded from Australia. Four new species are described, all in the subgenus Acauloplacella. The Australian representatives are related to those in New Guinea. All species occur in rainforest, especially along the margins. They are known from the east coast from disjunct populations from Iron Range south to near Townsville, Qld. They are nocturnal plant feeders with males uttering a stuttering call after dark.
