Taxonomy of the Genus Pseudonaja (Reptilia: Elapidae) in Australia
AUSTRALIAN BIODIVERSITY RECORD ________________________________________________________ 2002 (No 7) ISSN 1325-2992 March, 2002 ________________________________________________________ Taxonomy of the Genus Pseudonaja (Reptilia: Elapidae) in Australia. by Richard W. Wells “Shiralee”, Major West Road, Cowra, New South Wales, Australia The clear morphological differences that exist within the genus as previously considered strongly indicate that it is a polyphyletic assemblage. Accordingly, I have taken the step of formally proposing the fragmentation of Pseudonaja. In this work I have decided to restrict the genus Pseudonaja to the Pseudonaja nuchalis complex. Additionally, I herein formally resurrect from synonymy the generic name Euprepiosoma Fitzinger, 1860 for the textilis group of species, erect a new generic name (Placidaserpens gen. nov.) for the snakes previously regarded as Pseudonaja guttata, erect a new generic name (Notopseudonaja gen. nov.) for the group of species previously regarded as the Pseudonaja modesta complex, and erect a new generic name (Dugitophis gen. nov.) for snakes previously regarded as the Pseudonaja affinis complex. Genus Pseudonaja Gunther, 1858 The Pseudonaja nuchalis Complex It is usually reported that Pseudonaja nuchalis occurs across most of northern, central and western Australia, ranging from Cape York Peninsula, in the north-east, through western, southern and south-eastern Queensland, far western New South Wales, north-western Victoria, and most of South Australia, Northern Territory and Western Australia. However, this distribution pattern is now known to actually represents several different species all regarded by most authorities for convenience as the single highly variable species, 'Pseudonaja nuchalis'. As usually defined, this actually is a highly variable and therefore confusing group of species to identify and it is not all surprising that there has been difficulty in breaking up the group.
