(Zoology) Calorx Teachers' University, Ahmedabad Abstract A new species of the genus Lycodon Fitzinger, 1826 is described from the Cardamom Mountains of southwest Cambodia.Lycodon zoosvictoriae distinctly differs from all other species of Lycodon in Southeast Asia by a combination of its morphometric characters and unique coloration. The new species has 17 dorsal scales at midbody; 2+2 temporals; 8 supralabials; 10 infralabials; loreal separated from internasal and orbit; 213 ventrals; 85 subcaudals; pale tan brown ground color,irregular dark brown blotches on anterior part, 31 transverse blotches on posterior part of body and 26 blotches on tail.Given its submontane type locality, the new species could prove to be endemic to the Cardamom Mountains of southwestCambodia and probably Southeast Thailand. Key words: herpetofauna, Pursat, Indochina, Lycodon Introduction A new species of wolf snake is described from the tropical mixed dry deciduous forests of the Anaikatti Hills, Western Ghats, India. This species is distinct from its congeners of the Indian mainland by the following combination of characters: dorsal scales in 17:17:15 rows, scales smooth with single apical pit; anterior nasal shield larger than the posterior, loreal in contact with the internasal, but not with the eye; higher number of ventrals (210 - 224) which do not angulate laterally and hemipenis not forked at the tip and lacks spines.

Popularly called the double-headed snake, it has a blunt tail almost resembling a head which is wedge-shaped with narrow nostrils and tiny eyes. Taxonomically, it is placed in the class Reptilia, order Serpentes, and family Boidae. “It is the largest of the sand “ It is a nocturnal species and spends majority of boas in the world and can It is an ovoviviparous its time under the “ grow to more than 4ft species which means that ground. long.” ” the embryo that develops inside the eggs remains within the mother's body until they hatch into young ones. ” “ It feeds mainly on rodents, #DYK lizards and even other snakes. ” “It is easily recognisable due to its shovel-shaped nose and a blunt tail which appears to be chopped off. ” ECOLOGICAL ROLE: Just like other snake species, Red Sand Boa also plays a significant role in the ecosystem by maintaining a healthy population between prey and the predator.

Its diet is specialized in gastropods (Oliveira, detected, injured or killed by predators, and they possess 2001; Marques et al., 2015). an array of such behaviours (see a review in Greene, Taeniophallus occipitalis is a terrestrial, diurnal species 1988). The family Dipsadidae is widespread in the New that is found in leaf-litter (Sawaya et al., 2008; Morato et World and exhibits a high species diversity in Central al., 2011; Marques et al., 2015) of open vegetation types and South America, and the West Indies (Zaher et al., of the Cerrado (Scrocchi and Giraudo, 2005; França 2009; Vidal et al., 2010).

  • Genus Lycodon)
    Zoologica Scripta Multilocus phylogeny reveals unexpected diversification patterns in Asian wolf snakes (genus Lycodon) CAMERON D. SILER,CARL H. OLIVEROS,ANSSI SANTANEN &RAFE M. BROWN Submitted: 6 September 2012 Siler, C. D., Oliveros, C. H., Santanen, A., Brown, R. M. (2013). Multilocus phylogeny Accepted: 8 December 2012 reveals unexpected diversification patterns in Asian wolf snakes (genus Lycodon). —Zoologica doi:10.1111/zsc.12007 Scripta, 42, 262–277. The diverse group of Asian wolf snakes of the genus Lycodon represents one of many poorly understood radiations of advanced snakes in the superfamily Colubroidea. Outside of three species having previously been represented in higher-level phylogenetic analyses, nothing is known of the relationships among species in this unique, moderately diverse, group. The genus occurs widely from central to Southeast Asia, and contains both widespread species to forms that are endemic to small islands. One-third of the diversity is found in the Philippine archipelago. Both morphological similarity and highly variable diagnostic characters have contributed to confusion over species-level diversity. Additionally, the placement of the genus among genera in the subfamily Colubrinae remains uncertain, although previous studies have supported a close relationship with the genus Dinodon. In this study, we provide the first estimate of phylogenetic relationships within the genus Lycodon using a new multi- locus data set. We provide statistical tests of monophyly based on biogeographic, morpho- logical and taxonomic hypotheses. With few exceptions, we are able to reject many of these hypotheses, indicating a need for taxonomic revisions and a reconsideration of the group's biogeography. Mapping of color patterns on our preferred phylogenetic tree suggests that banded and blotched types have evolved on multiple occasions in the history of the genus, whereas the solid-color (and possibly speckled) morphotype color patterns evolved only once.

Key words: reptiles; amphibians; keys; Annapurna region; Dhaulagiri region; Nepal; altitudinal distribution; zoogeography. The reptiles and amphibians of the Annapurna-Dhaulagiri region in Nepal are keyed and described. Their distribution is recorded, based on both personal observations and literature data. The ecology of the species is discussed. The zoogeography and the altitudinal distribution are analysed.
