|Abstract:||Based on a combination of morphological and genetic data, geographically isolated populations of Pygopus from north-eastern Queensland, formerly referred to Pygopus lepidopodus (Lacépède), are herein described as a new species. Pygopus robertsi sp. nov. can be diagnosed from its congeners by a suite of scalation characters, including fewer keeled dorsal scales, presence of a single continuous row of supracilaries and a lower number of midbody scale rows. It is also deeply divergent genetically from samples of Pygopus lepidopodus from southern Australia. The known distribution of Pygopus robertsi sp. nov. is similar to that of a number of taxa centred upon relatively dry ecotonal habitats at the western edge of the rainforest blocks of north-eastern Queensland. Additional samples and systematic work will be required to examine the evolutionary divergence of apparently isolated populations of the new species, and the significance of considerable genetic and morphological diversity within remaining populations of Pygopus lepidopodusfrom south-eastern and southern Australia.|
