Introduction

Zhang and Webb (1996) recognised five Indian species of the genus as well as single species in Taiwan, Austalia and Sri Lanka. Viraktamath (1998) added a further 11 species from India and arranged the fauna into three species groups based on the arrangement of the male genitalia. Fletcher and Semeraro (2007) added four more species from Australia, one of which was brought into the genus by the synonymy of Exitianellus Evans. Interestingly, all three species groups recognised by Viraktamath (1998) are present in the Australian fauna.

Diagnosis

The Australian species of Carvaka are all medium-sized (4–6 mm), pale coloured leafhoppers with elongate antennae and fine, transverse corrugations along the anterior margin of the head. The vertex is marked with either a transverse dark band or distinct spots (Fletcher & Semeraro 2007).
