New Records and an Updated List of Lizards from Son La Province, Vietnam Herpetology Notes, volume 11: 209-216 (2018) (published online on 09 March 2018) New records and an updated list of lizards from Son La Province, Vietnam Anh Van Pham1, Hoang Van Tu1, Tan Van Nguyen2, Thomas Ziegler3,4 and Truong Quang Nguyen2,5,* Abstract. We report five new records of lizards from Son La Province, namely Pseudocalotes brevipes (Agamidae), Gekko palmatus, Hemidactylus garnotii (Gekkonidae), Ateuchosaurus chinensis and Sphenomorphus cryptotis (Scincidae). In addition we provide an updated list of 32 lizard species from Son La Province. Key words: Lizards, new records, morphology, taxonomy, Son La Province Introduction Material and Methods Although Son La Province contains a large area of Sampling. Field surveys were conducted in 440,000 hectares of natural forest (People’s Committee northwestern Vietnam by Anh Van Pham, Tan Van of Son La Province, 2007), the lizard fauna of this Nguyen, Kham Di Pheng Kia, Nenh Ba Song, and province is still poorly studied. Hikida and Darevsky Hoang Van Tu (hereafter AVP et al.) between April 2013 (1987) recorded only one species of Scincidae, namely and June 2016 in the Copia, Muong La, Xuan Nha, and Eumeces tamdaoensis (Bourret, 1937). Further new Sop Cop nature reserves and Muong Do District, Son records of lizards from Son La Province were published La Province (Fig. 1). Specimens were collected by hand by Bobrov and Ho (1993), Nguyen et al. (2009), Ngo between 8:00 and 22:00. Specimens were photographed and Grismer (2010), Nguyen et al. (2010), and Pham in life and euthanized in a closed vessel with a piece et al. (2015). As a result of these studies a total of 27 of cotton wool containing ethyl acetate (Simmons, species of lizards were recorded from this province. 2002), fixed in 85% ethanol and subsequently stored Based on our recent field work in Copia, Muong La, in 70% ethanol. Voucher specimens were subsequently Sop Cop, and Xuan Nha nature reserves and Muong Do deposited in the collections of the Tay Bac University District of Son La Province between 2013 and 2016 we herein provide new records of lizards and an updated checklist of lizard species from Son La. 1 Faculty of Biology and Chemistry, Tay Bac University, Quyet Tam Ward, Son La City, Son La Province, Vietnam 2 Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet Road, Hanoi, Vietnam 3 AG Zoologischer Garten Köln, Riehler Strasse 173, D-50735 Cologne, Germany 4 Institute of Zoology, University of Cologne, Zülpicher Strasse 47b, D-50674 Cologne, Germany 5 Graduate University of Science and Technology, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet Road, Cau Giay, Hanoi, Vietnam Figure 1.

(Rhabdiasidae) and Hedruris miyakoensis sp. n. (Hedruridae) are described from skinks of the Ryukyu Archipelago, Japan. Neoentomelas asatoi from the lung of Ateuchosaurus pellopleurus on Okinawa and Amami-oshima islands is distinguished from all other rhabdiasids in having well- developed dorsoventral lips with posteriorly directed lobulate formations. Hedruris miyakoensis from the stom- ach of Scincella boettgeri on Miyako Island differs from other species of the genus by the simple lateral cuticular structures of the interlabia, eggs without peripheral swellings, absence of preanal unpaired papilla, stout spicules with prominent accessory structure, simple hook of the holdfast, and/or difference in the measurements.

  • Genetic Structure of Mediterranean Sea Turtle Populations
    Turk J Zool 24 (2000) 191–197 © TÜBİTAK Genetic Structure of Mediterranean Sea Turtle Populations Yakup KASKA Pamukkale University, Faculty of Science and Literature, Department of Biology, Denizli-TURKEY Received: 20.04.1999 Abstract: The mitochondrial DNA (mtDNA) control region sequences of two species (Caretta caretta and Chelonia mydas) of sea turtles from the Mediterranean were analysed using samples from Northern Cyprus. Only one single haplotype for each species was detected. These results were compared with other published work regarding the genetic structure of sea turtle populations. These results suggest that the Mediterranean population of sea turtles were separated from their Atlantic relatives in the recent past. In order to protect these endangered sea turtles and to preserve the genetic diversity of the sea turtle population in the Mediterranean, individual nesting sites must be protected. That genetic studies can be done on the systematics of vertebrates, especially taxonomic studies of Herpetofauna, has also been shown by other related literature. Key Words: Chelonia mydas, Caretta caretta, genetic diversity, DNA sequence. Akdeniz Deniz Kaplumbağa Populasyonlarının Genetik Yapısı Özet: Akdeniz’deki iki deniz kaplumbağası (Chelonia mydas ve Caretta caretta) türlerinin mitokondriyel DNA kontrol bölgesi sekuens analizi, Kuzey Kıbrıs’tan toplanan örnekler kullanılarak yapılmıştır. Her tür için tek tip haplotip tesbit edilmiştir. Bu sonuçlar deniz kaplumbağa populasyonlarının genetik yapısı ile ilgili araştırmaların sonuçları ile karşılaştırılmıştır ve bu sonuçlar Akdeniz deniz kaplumbağalarının Atlantik akrabalarından yakın bir zaman önce ayrılmış olduklarını göstermiştir. Tehlike altındaki bu deniz kaplumbağalarını ve Akdeniz’deki mevcut genetik çeşitliliği korumak için her yuvalama bölgesinin de korunması gerekmektedir. Genetik çalışmaların omurgalılarda ve özellikle herpetofauna ile ilgili taksonomik çalışmalarda kullanılabileceği diğer literatürler ışığında gösterilmiştir.

HAU School of Biological Sciences, The University of Hong Kong, Pokfulam Road, Hong Kong SAR, China 1Corresponding author, email: [email protected] Abstract.—Southeast Asia exhibits high herpetofaunal biodiversity, yet many areas and taxa in the region remain understudied. Extensive surveys are needed to fill information gaps, yet at present we have little knowledge about the effectiveness of different herpetofaunal survey methods in the region. We conducted field studies to examine the effectiveness of three survey methods for sampling terrestrial amphibians and reptiles in Hong Kong. Transect surveys were the most effective at sampling species richness and drift fences with pitfall traps and funnel traps were the most efficient in capturing high numbers of reptiles. We recommend the use of transect surveys for rapid biodiversity assessment and the combination of transect surveys and pitfall traps for comprehensive species inventories. Pitfall traps represent an excellent tool for surveys or population monitoring of leaf litter species. The results of this study will aid researchers in assessing the feasibility of and in choosing herpetofaunal survey methods in Southeast Asia.

  • Using Ancient and Recent DNA to Explore Relationships of Extinct and Endangered Leiolopisma Skinks (Reptilia: Scincidae) in the Mascarene Islands
    Molecular Phylogenetics and Evolution 39 (2006) 503–511 www.elsevier.com/locate/ympev Using ancient and recent DNA to explore relationships of extinct and endangered Leiolopisma skinks (Reptilia: Scincidae) in the Mascarene islands J.J. Austin 1, E.N. Arnold ¤ Department of Zoology, Natural History Museum, Cromwell Rd., London SW7 5BD, UK Received 29 August 2005; revised 15 December 2005; accepted 15 December 2005 Available online 10 February 2006 Abstract Phylogenetic analysis, using 1455 bp of recent mtDNA (cytochrome b 714 bp, 12S rRNA 376 bp) and nuclear (c-mos 365 bp) sequence from 42 species and 33 genera of Scincidae, conWrms Leiolopisma telfairii, now conWned to Round island oV Mauritius, is a member of the mainly Australasian Eugongylus group of the Lygosominae. Ancient mtDNA (cytochrome b 307 bp, 12S rRNA 376 bp) was also extracted from subfossils of two other Mascarene taxa that are now extinct: the giant L. mauritiana from Mauritius and Lei- olopisma sp., known only from fragmentary remains from Réunion. Sequence divergences of 4.2–5.7% show that all three forms were distinct and form a clade. There is restricted evidence that L. mauritiana and L. sp. from Réunion were sister species. Monophyly and relationships suggest Leiolopisma arose from a single transmarine invasion of the oceanic Mascarene islands from Australasia, 5600– 7000 km away. This origin is similar to that of Cryptoblepharus skinks and Nactus geckos in the archipelago but contrasts with Phel- suma day geckos, which appear to have arrived from Madagascar where Mascarene Cylindraspis tortoises may also have originated. DiversiWcation of the known species of Leiolopisma occurred from about 2.3–3.4 Mya, probably beginning on Mauritius with later invasion of Réunion.
