Geographic variation in potoroos (genus Potorous) from south-eastern Australia and Tasmania was investigated by electrophoretic and chromosomal techniques. Six of the 10 potoroo blood proteins examined showed electrophoretic variation and the genetic basis of three of these was established by breeding studies. Levels of genic heterozygosity were similar in Tasmanian and mainland populations. Coefficients of genetic similarity based on 10 loci indicated that potoroos from Tasmania and the Bass Strait islands are similar to each other but different from those of mainland Australia. No chromosomal variation was observed in potoroos examined from south-eastern Australia and Tasmania. Crosses between animals from these regions produced fertile offspring. It is concluded from this study and a related investigation on morphological variation that the genus Potorous should be separated into two species, P. platyops and P. tridactylus, with the further subdivision of the latter species into P.t. tridactylus from mainland Australia (including P. gilberti) and P.t. apicalis from Tasmania and the Bass Strait islands.
