Abstract

A chromosomal analysis of the gekko Gehyra australis (KING in press) revealed the presence of a series of genetically distinct chromosome races. Specimens from four of these chromosome races have been analysed morphologically. The present study indicates that each chromosome race can be specified in terms of pattern, colouration, scalation and morphometrics. The species Gehyra australis is therefore redefined, and a number of new species are described. Members of the Gehyra australis species group are listed, and a key to their diagnostic characteristics is provided.

Three new species of the gekkonid genus Oedura, collected in the Mitchell plateau area of North Western Australia are described. These very distinctive animals are sympatric in their distribution, but differ markedly in size and morphology. They probably utilize different microhabitats.
