ABSTRACT As part of an ongoing audit of Australian reptiles, specimens of the little-known South-west Australian Snake species Narophis bimaculata (Duméril, Bibron and Duméril, 1854) from across the known range of the putative species were examined. It was found to comprise three allopatric and geographically distinct forms, worthy of taxonomic recognition. The two unnamed forms are herein formally described as species in accordance with the rules of the International Code of Zoological Nomenclature (Ride et al. 1999) as amended. Narophis richardwellsei sp. nov. is the species from the Eyre Peninsula and nearby parts of South Australia. Narophis cliffrosswellingtoni sp. nov. is the form found in most parts of southern Western Australia, except for the lower west coast and coastal plain from Green Head south to Bunbury (including Perth and environs), being the area inhabited by the nominate form Narophis bimaculata. The genus Narophis was erected by Worrell in 1961 as monotypic for the species Furina bimaculata Duméril, Bibron and Duméril, 1854, however the name has not been used since in Australian herpetology on the basis that the original publication of Worrell was not peer reviewed (see Kaiser et al.

Westbrooke, Centre for Environmental Management, University of Ballarat Nanya Station, owned and managed by the University of Ballarat was purchased with assistance from the Department of Environment and Heritage. Ongoing management is supported by the Lower Murray Darling Catchment Management Authority FOREWORD 1 FOREWORD This booklet has been prepared as an introduction for visitors to Nanya. Nanya is managed for conservation, research and teaching and affords protection to highly significant environments including two endangered communities and seventeen endangered or vulnerable species. On your visit, please respect these values. NANYA STATION Nanya Station is located in the Scotia country of far western New South Wales and consists of the Nanya Western Lands Pastoral Lease 3281 – Perpetual Leasehold Lot 1244 in Deposited Plan 762778, Parish of Winnebaga, County of Tara. Nanya Homestead complex 2 BACKGROUND The Scotia region has one of the shortest stock grazing histories of western NSW. Along with five other properties, Nanya was created as a pastoral lease in 1927. Previously the area was part of the large Lake Victoria lease and stock grazing occurred only in wet years (Withers 1989). The original lease was taken up by Gordon Cummings in 1927. He first dug a dam near the southeast corner of the property. A larger ground tank and homestead at the site of the present complex was later established. An area around the homestead was cleared and cropped to provide feed for the horses used in digging the earth tanks. The ruins of the original building are located between the shearing shed and Homestead Tank.

  • Sand-Swimming' Snake Species (Simoselaps: Elapidae) in South-Western Australia
    J. Zool., Lond. (1999) 249, 269±282 # 1999 The Zoological Society of London Printed in the United Kingdom Ecological traits and conservation biology of ®ve fossorial `sand-swimming' snake species (Simoselaps: Elapidae) in south-western Australia Richard A. How1 and Richard Shine2* 1 Museum of Natural Sciences, Francis Street, Perth, WA 6000, Australia 2 Biological Sciences A08, University of Sydney, NSW 2006, Australia (Accepted 29 January 1999) Abstract Although small, nocturnal, fossorial snakes are a signi®cant component of the reptile fauna in many parts of the world, their biology is poorly known. An 11-year pit-trapping study in urban bushland remnants near the city of Perth, Western Australia, provided data from > 500 captures of small fossorial snakes of the genus Simoselaps. The ®ve species differed in relative abundances and in distribution, both among localities and among habitats within a single locality. For example, three saurophagous taxa (Simoselaps bertholdi, S. bimaculatus, S. calonotos) were most abundant in Banksia woodland, whereas two species that feed on reptile eggs (S. semifasciatus, S. fasciolatus) were most abundant in coastal heath. Capture rates for most species were low (for three of the ®ve species, < one specimen captured per 1000 trapdays), and these taxa may be genuinely rare in most of the habitats that we surveyed. Activity patterns were highly seasonal, with little activity in winter or in midsummer. The two oophagous species showed a more restricted activity period (late spring±early summer) than did species with broader dietary habits. In the most abundant taxon (Simoselaps bertholdi), males were active mainly during spring (the mating season) and females during autumn, after oviposition.

These sitE's were not overtlv affected by secondarv salinisation, but did include sites that were 'natu~ally' saline. We recorde~i a total of 144 species from 74 genera and 15 families. There was an average of 10.4 species per quadrat with a range from one to 19. Vertebrate species richness was highest on dissection valley floors and sandy depositional surfaces of the 'old plateau' but lowest on saltflats. Total species richness was positively correlated with high levels of sand, with low levels of soil nutrients and with good soil drainage. When frogs, reptiles and mammals were considered separately, temperature and rainfall attributes were also shown to exhibit correlations with species richness. Patterns in species composition could be explained in terms of climatic and substrate variables, including salinity. Two distinct faunas were identified - one concentrated in the semi-arid northern and inland parts of the study area, and one concentrated in the more mesic south and south-east.

  • Reptiles of Dirk Hartog Island Mark Cowan (October 2018)
    Reptiles of Dirk Hartog Island Mark Cowan (October 2018) Dirk Hartog Island has a rich reptile fauna with over 40 species recorded. This is more species than most other Western Australian islands which is probably due, in part, to the large size of the island (620 km2), and to the relatively short time it has been isolated from the mainland. The species recorded on the island include four dragons (Family Agamidae), eight geckos (families Carphodactylidae, Diplodactylidae and Gekkonidae), five legless lizards (family Pygopodidae), fifteen skinks (family Scincidae), one goanna (family Varanidae), eight front fanged snakes (family Elapidae), one python (family Pythonidae) and one blind snake (family Typhlopidae). While no species are endemic to the island, a number are endemic to Western Australia with several of these having distributions restricted along the adjacent Western Australian coast or to the Shark Bay area. Species confined more or less to the Shark Bay area are Ctenophorus butloreum (Shark Bay Heath Dragon), Aprasia haroldi (Shark Bay Worm-Lizard), Ctenotus youngsoni (Shark Bay Sand Ctenotus) and, Lerista varia (Variable-striped Robust Slider). A fifth species, Egernia stokesii (Stokes’ Skink) has a subspecies (Egernia stokesii badia) occurring on Dirk Hartog Island that is a threatened species; listed as vulnerable under the WA Biodiversity Conservation Act 2016 and as endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. It is a relatively large and robust skink covered in small spiny scales and is approximately 190mm head-body length. It usually occupies rocky environments or hollow logs. The following pages show all but one of the recorded species, Demansia calodera (black-necked whipsnake).
