DOI: 10.18195/issn.0312-3162.25(2).2009.181-199 Records of the Western Australian Museum 25: 181–199 (2009). Three new species of Ctenotus (Reptilia: Sauria: Scincidae) from the Kimberley region of Western Australia, with comments on the status of Ctenotus decaneurus yampiensis Paul Horner Museum and Art Gallery of the Northern Territory, GPO Box 4646, Darwin, Northern Territory 0801, Australia. E-mail: [email protected] Abstract – Three new species of Ctenotus Storr, 1964 (Reptilia: Sauria: Scinci- dae), C. halysis sp. nov., C. mesotes sp. nov. and C. vagus sp. nov. are described. Previously confused with C. decaneurus Storr, 1970 or C. alacer Storr, 1970, C. halysis sp. nov. and C. vagus sp. nov. are members of the C. atlas species com- plex. Ctenotus mesotes sp. nov. was previously confused with C. tantillus Storr, 1975 and is a member of the C. schomburgkii species complex. The new taxa are terrestrial, occurring in woodland habitats on sandy soils in the Kimberley region of Western Australia and are distinguished from congeners by combi- nations of body patterns, mensural and meristic characteristics. Comments are provided on the taxonomic status of C. yampiensis Storr, 1975 which is considered, as in the original description, a subspecies of C. decaneurus. Re- descriptions of C. d. decaneurus and C. d. yampiensis are provided. Keywords – Ctenotus alacer, decaneurus, yampiensis, halysis, mesotes, tantillus, vagus, morphology, new species, Kimberley region, Western Australia INTRODUCTION by combinations of size, scale characteristics, body Ctenotus Storr, 1964 is the most species-rich genus colour and patterns. of scincid lizards in Australia, with almost 100 taxa recognised (Horner 2007; Wilson and Swan 2008). -

Ellis Department of Terrestrial Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Western Australia 6986, Australia. Biologic Environmental Survey, 24–26 Wickham St, East Perth, Western Australia 6004, Australia. Email: [email protected] ABSTRACT – The Western Australian Museum holds a vast collection of specimens representing a large portion of the 106 currently recognised taxa of dragon lizards (family Agamidae) known to occur across Australia. While the museum’s collection is dominated by Western Australian species, it also contains a selection of specimens from localities in other Australian states and a small selection from outside of Australia. Currently the museum’s collection contains 18,914 agamid specimens representing 89 of the 106 currently recognised taxa from across Australia and 27 from outside of Australia. This includes 824 type specimens representing 45 currently recognised taxa and three synonymised taxa, comprising 43 holotypes, three syntypes and 779 paratypes. Of the paratypes, a total of 43 specimens have been gifted to other collections, disposed or could not be located and are considered lost. An annotated catalogue is provided for all agamid type material currently and previously maintained in the herpetological collection of the Western Australian Museum. KEYWORDS: type specimens, holotype, syntype, paratype, dragon lizard, nomenclature. INTRODUCTION Australia was named by John Edward Gray in 1825, The Agamidae, commonly referred to as dragon Clamydosaurus kingii Gray, 1825 [now Chlamydosaurus lizards, comprises over 480 taxa worldwide, occurring kingii (Gray, 1825)]. -
Ngangkan Culture Camp and Biodiversity Survey
Ngangkan Culture Camp and Biodiversity Survey June 2013 Where and Why? Our camp was on Ngangkan in Ngolkwarre country, in the Warddeken IPA on the western Arnhem Plateau, Northern Territory. The elders chose Ngangkan for the families to camp because it is a peaceful place, away from town, with lots of bush tucker; a place to bring back memories to share and a place for kids to learn about cultural knowledge. Warddeken Indigenous Protected Area is funded to look after the country and its animals. Every year, the Warddeken rangers do surveys to look for animals and to build up a picture of what is happening with the animals over time. Surveys have been done at Ngangkan since 2012 and the same sites are visited each year to see if the animal numbers are changing. It is planned to use Ngangkan as a long term monitoring site to keep a check on animal numbers in Warddeken IPA. 2 Who was there? • Rangers and Traditional Owners of the Warddeken IPA from the Manmoyi and Kamarrkawarn ranger bases, with their families and lots of kids as it was the school holidays • Scientists Alys Stevens and Terry Mahney from Flora and Fauna Division (NT Govt) • Manmoyi Outstation school teacher – Dan McLaren • Volunteer Doctor – Gabby Hall • Georgia Vallance – Warddeken Coordinator 3 3 What we did Cultural activities Cultural activities included; gathering (bushtucker, cultural materials like pandanas, digging sticks), knowledge sharing in evenings, corroboree with singing and dancing, traditional cooking, making music with traditional instruments and knowledge sharing everyday as part of life. Berribob taught the boys and young men how to make shovel spears, spear throwers and make fire in preparation for a fire drive to hunt kangaroo. -

A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata). Caribbean Herpetology 49:1–61. Abstract The evolutionary history and taxonomy of worm-like snakes (scolecophidians) continues to be refined as new molec- ular data are gathered and analyzed. Here we present additional evidence on the phylogeny of these snakes, from morphological data and 489 new DNA sequences, and propose a new taxonomic framework for the family Typhlopi- dae. Of 257 named species of typhlopid snakes, 92 are now placed in molecular phylogenies along with 60 addition- al species yet to be described. Afrotyphlopinae subfam. nov. is distributed almost exclusively in sub-Saharan Africa and contains three genera: Afrotyphlops, Letheobia, and Rhinotyphlops. Asiatyphlopinae subfam. nov. is distributed in Asia, Australasia, and islands of the western and southern Pacific, and includes ten genera:Acutotyphlops, Anilios, Asiatyphlops gen. -
Survey of Reptiles and Amphibians at Bimblebox Nature Reserve - Queensland
Summary of an Observational Survey of Reptiles and Amphibians at Bimblebox Nature Reserve - Queensland Graham Armstrong – May, 2016 Objective - to provide an updated and more complete list of the herpetofauna recorded from Bimblebox Nature Refuge. Approach - 1. Review available data and records pertaining to the herpetofauna at Bimblebox Nature Refuge. 2. Visit Bimblebox Nature Refuge during Spring, Summer and Autumn seasons to make observational and photographic records of the herpetofauna observed. Methodology - In order to maximise the number of species recorded, 3 successive 2.5 day visits were made to BNR, one in September 2015, Jan 2016 and the end of April 2016. This approach potentially broadens the range of weather conditions experienced and hence variety of reptiles and amphibians encountered when compared to a single field visit. Survey methodology involved walking and driving around the nature refuge during the day and after dark (with the aid of a head torch to detect eye-shine). Active reptiles including those that ran for or from cover while passing by were recorded. Frequently, in situ photographic evidence of individuals was obtained and the photographs are available for the purpose of corroborating identification. To avoid any double counting of individual animals the Refuge was traversed progressively and the locations of animals were recorded using a GPS. During any one visit no area was traversed twice and when driving along tracks, reptiles were only recorded the first time a track was traversed unless a new species was detected at a later time. Available Records The most detailed list of reptiles and amphibians recorded as occurring on Bimblebox Nature Reserve comes from the standardised trapping program of Eric Vanderduys of CSIRO in Townsville. -

SHEA Faculty of Veterinary Science B01, University of Sydney, NSW 2006, Australia and Australian Museum Research Institute, Australian Museum, 6 College St, Sydney, NSW 2010, Australia. E-mail: [email protected] Abstract Anilios fossor sp. nov. is described from a single specimen collected in 1989 from Ruby Gap Nature Park, Northern Ter- ritory. The species differs from all other Anilios species in the combination of 20 midbody scales, 514 dorsal scales, a rounded, non-angulate snout in lateral and dorsal profile, a nasal cleft contacting the second supralabial and not extending to the head dorsum, and a large round rostral shield in dorsal view. It is unclear whether the paucity of material of this species represents a limited distribution, or poor sampling in a remote, sparsely settled part of the continent. Evidence for the recognition of the Australian typhlopid fauna as a distinct genus Anilios is critically reviewed, and the genus is found to be recognizable only on genetic evidence. Some other recent nomenclatural and taxonomic changes in the Australian typhlopid fauna are considered and rejected. Key words: Reptilia, Squamata, Serpentes, morphology, systematics, nomenclature, Northern Territory Introduction Modern knowledge of the typhlopid snake fauna of Australia began almost a century ago with a monographic treatment by Waite (1918).
