The study was based on morphological features including color pattern, morphometric measurements, habits, biological observations especially habitat and distribution. Habits features, habitat and new distribution localities were documented. This is the first record of Calotes versicolor from the Kalesari village is 44 km away from the last record in Nahang River. Key words: Agamidae, Calotes versicolor, Distribution, Habits, Habitats, Iran. INTRODUCTION The genus Calotes Cuvier, 1817 belongs to the family Agamidae and contains at least 26 species distributed in South and Southeast Asia (Uetz & Hosek, 2016) and only one species reported from Iran (Anderson, 1999; Rastegar-Pouyani et al., 2008; Šmíd et al., 2014). Calotes versicolor (Daudin, 1802) has a wide distribution in Afghanistan, Iran, Pakistan, Nepal, Bhutan, India, Sri Lanka, Myanmar, southern China (Yunnan, Hainan Island, Hong Kong), Laos, Thailand, Vietnam, Singapore, western Malaysia, Indonesia (Sumatra) (Ananjeva et al.

We present the first record of the Genus Calamaria from Karimunjawa Island, Central Java, Indonesia based on an unfathomable single specimen collected in the coastal forest of Legon Moto. Morphological characters analysis revealed the specimen as Calamaria melanota. This finding unravels the extent of the species distribution which was previously thought to be restricted in Borneo, representing the southernmost record of this species. The examined specimen is described in detail and meticulously compared with other Calamaria species such as C. battersbyi, C. borneensis, C. linnaei. Our study highlights several characteristic differences between the specimen and the holotype of C. melanota. Keywords: Biogeography, Calamaria, morphology, snake, systematic INTRODUCTION the surrounding small islands, there are 10 species, C.

    Evolutionary History of the Asian Horned Frogs (Megophryinae): Integrative Approaches to Timetree Dating in the Absence of a Fossil Record Stephen Mahony,*,1,2 Nicole M. Foley,1 S.D. Biju,2 and Emma C. Teeling*,1 1School of Biology and Environmental Science, University College Dublin, Belfield, Dublin, Ireland 2Systematics Lab, Department of Environmental Studies, University of Delhi, Delhi, India *Corresponding authors: E-mails: [email protected]; [email protected]. Associate editor: Beth Shapiro Abstract Downloaded from https://academic.oup.com/mbe/article-abstract/34/3/744/2919384 by guest on 06 August 2019 Molecular dating studies typically need fossils to calibrate the analyses. Unfortunately, the fossil record is extremely poor or presently nonexistent for many species groups, rendering such dating analysis difficult. One such group is the Asian horned frogs (Megophryinae). Sampling all generic nomina, we combined a novel 5 kb dataset composed of four nuclear and three mitochondrial gene fragments to produce a robust phylogeny, with an extensive external morpho- logical study to produce a working taxonomy for the group. Expanding the molecular dataset to include out-groups of fossil-represented ancestral anuran families, we compared the priorless RelTime dating method with the widely used prior-based Bayesian timetree method, MCMCtree, utilizing a novel combination of fossil priors for anuran phylogenetic dating. The phylogeny was then subjected to ancestral phylogeographic analyses, and dating estimates were compared with likely biogeographic vicariant events. Phylogenetic analyses demonstrated that previously proposed systematic hypotheses were incorrect due to the paraphyly of genera. Molecular phylogenetic, morphological, and timetree results support the recognition of Megophryinae as a single genus, Megophrys, with a subgenus level classification.

  • Colubrid Venom Composition: an -Omics Perspective
    toxins Review Colubrid Venom Composition: An -Omics Perspective Inácio L. M. Junqueira-de-Azevedo 1,*, Pollyanna F. Campos 1, Ana T. C. Ching 2 and Stephen P.

Because rear-fanged snakes are a diverse and distinct radiation of the advanced snakes, understanding venom composition among “colubrids” is critical to understanding the evolution of venom among snakes. Here we review the state of knowledge concerning rear-fanged snake venom composition, emphasizing those toxins for which protein or transcript sequences are available. We have also added new transcriptome-based data on venoms of three species of rear-fanged snakes. Based on this compilation, it is apparent that several components, including cysteine-rich secretory proteins (CRiSPs), C-type lectins (CTLs), CTLs-like proteins and snake venom metalloproteinases (SVMPs), are broadly distributed among “colubrid” venoms, while others, notably three-finger toxins (3FTxs), appear nearly restricted to the Colubridae (sensu stricto).

  • Reptiles of Phetchaburi Province, Western Thailand: a List of Species, with Natural History Notes, and a Discussion on the Biogeography at the Isthmus of Kra
    The Natural History Journal of Chulalongkorn University 3(1): 23-53, April 2003 ©2003 by Chulalongkorn University Reptiles of Phetchaburi Province, Western Thailand: a list of species, with natural history notes, and a discussion on the biogeography at the Isthmus of Kra OLIVIER S.G.

On the basis of a review of available literature, original field observations and examination of museum collections, a preliminary list of 81 species (12 chelonians, 2 crocodiles, 23 lizards, and 44 snakes) is established, of which 52 (64 %) are reported from the province for the first time. The possible presence of additional species is discussed. Some biological data on the new specimens are provided including some range extensions and new size records. The herpetofauna of Phetchaburi shows strong Sundaic affinities, with about 88 % of the recorded species being also found south of the Isthmus of Kra. A biogeographic affinity analysis suggests that the Isthmus of Kra plays the role of a biogeographic filter, due both to the repeated changes in climate during the Quaternary and to the current increase of the dry season duration along the peninsula from south to north.
