The phylogenetic relationships of the colubrine genus Coelognathus is examined on the basis of two partially sequenced mitochondrial genes, COI and 12S rRNA. Maximum parsimony reconstructions show that C. erythrurus , C. flavolineatus , C. helena , C. radiatus , and C. subradiatus share a common ancestor. Coelognathus spp. represent an evolutionary lineage among Oriental racers. Based on molecular data, external morphology, and pulmonary features, Coluber prasinus Blyth and Herpetodryas…

Additions to the phylogeny of colubrine snakes in Southwestern Asia, with description of a new genus and species (Serpentes: Colubridae: Colubrinae)
TLDR
An updated phylogeny of colubrid snakes from the Western Palearctic is presented by analyzing a supermatrix of all available global snake species with molecular data and the discovery of a new genus and species of Colubrine snake from southeastern Iran is reported.
Phylogenetic analysis of colubrid snakes based on 12S rDNA reveals distinct lineages of Dendrelaphis pictus (Gmelin, 1789) populations in Sumatra and Java
TLDR
Interestingly, two distinct clades of Dendrelaphis pictus species with the high genetic divergence between them are found where D. pictus from Sumatra and West Java separated from Central and East Java clade, showing that the differentiation between these clades occurred in the late Miocene epoch.
Late Hemphillian Colubrid Snakes (Serpentes, Colubridae) from the Gray Fossil Site of Northeastern Tennessee
TLDR
The Gray Fossil Site of northeastern Tennessee represents a poorly understood region of North America at a crucial time period in snake evolution, and its study may help to further understand the modern snake fauna present today in midcontinental and eastern North America.
Coalescent Species Tree Inference of Coluber and Masticophis
TLDR
The phylogenetic history of this group is examined using multi-locus data in a coalescent framework, where paraphyly of Masticophis would result in support for the recognition of only a single genus (Coluber) for these species.
Back from the dead! Resurrection and revalidation of the Indian endemic snake genus Wallophis Werner, 1929 (Squamata: Colubridae) insights from molecular data
TLDR
The monotypic colubrid snake genus Wallophis is revalidated and rediagnosed and Wallaceophis gujaratensis is proposed as the correct spelling for the species based on provisions in the International Code for Zoological Nomenclature.
Evolution, biogeography and systematics of the western Palaearctic Zamenis ratsnakes
TLDR
A comprehensive molecular data set for Zamenis and closely related ratsnakes to assess their phylogenetic and systematic relationships and infer their spatial and temporal modes of diversification, resulting in a fully resolved and well‐supported phylogeny which is consistent across markers, taxon‐sets and phylogenetic methods.
A Biogeographic Synthesis of the Amphibians and Reptiles of Indochina
TLDR
The first biogeographic synthesis of the regional herpetofauna since the first half of the 20th century is undertaken, and contribution of subtropical biota to Indochina's fauna is significantly greater than that of tropical biota and there is little other evidence for intermixing at intermediate latitudes.
Inventarisasi Jenis-jenis Ular ( Serpenthes ) di Kawasan Universitas Tanjungpura Pontianak
TLDR
To determine the types of snakes found and to find out the characteristics of each snake types in Tanjungpura University area Pontianak, the sampling research was done from March to May 2018, with the VES method.
Evolutionary history of selected squamates: insights from nuclear genes and species tree with implications for biogeography and taxonomy
TLDR
The phylogenetic position of most remaining genera was unresolved, corroborating the hypothesis of a hard polytomy in the Lacertini phylogeny due to a fast radiation, and it is shown that the supermatrix approach may provide high support for incorrect nodes that are not supported either by original sequence data or by new data from this study.
Analisis Kariotipe Ular Trawang (Coelognathus radiatus, (Boie 1827))
TLDR
Chromosome characters of the radiated ratsnake collected from Sewon, Bantul, Daerah Istimewa Yogyakarta has chromosome variation size indicating that radiated Ratsnake from Sew on, Bantamul, daerahIstimewA YogyAKarta has chromosomes variation size.

Molecular Systematics and Phylogeny of Old and New World Ratsnakes, Elaphe Auct., and Related Genera (Reptilia, Squamata, Colubridae)
TLDR
The phylogenetic relationships of the Holarctic ratsnakes (Elaphe auct.) are inferred from portions of two mitochondrial genes, 12S rRNA and COI, and another new genus is described for four Oriental species.
Hemerophis, a new genus for Zamenis socotrae Günther, and a contribution to the phylogeny of Old World racers, whip snakes, and related genera (Reptilia: Squamata: Colubrinae)
External morphology, skull bones, vertebrae, visceral topography and hemipenis features of the Sokotra racer were examined. Considerable differences exist vis-a-vis Palaearctic and East African
The phylogenetic significance of morphological characters in the Holarctic racers of the genus Coluber Linnaeus 1758 (reptilia, Serpentes)
TLDR
The results do not justify the separation of the genus Masticophis Baird and Girard from the single Nearctic species, C. constrictor Linnaeus, and changing or proposing new generic names for these groups must be avoided until the evolutionary polarity of characters is known for the Oriental and Ethiopian forms.
Systematics and phylogenetic relationships of Whip snakes (Hierophis Fitzinger) and Zamenis andreana Werner, 1917 (Reptilia: Squamata: Colubrinae)
TLDR
Morphological and molecular data of Coluber (sensu lato) andreanus and all recognised species of the Palaearctic whip snake genus Hierophis Fitzinger are presented and character states strongly support sister group relationship of dwarf snakes to Andreas' racer.
Molecular systematics of racers, whipsnakes and relatives (Reptilia: Colubridae) using mitochondrial and nuclear markers
TLDR
Inter- and subgeneric relationships among many of the Old World racer groups have been resolved and the position of ‘Coluber’ zebrinus along with Hemerophis socotrae located at the base of theOld World racer radiation forming the possible sister group to all remaining Palearctic racers and whipsnakes remains less well supported.
SACRUM AND PELVIC GIRDLE DEVELOPMENT IN LACERTIDAE
TLDR
This study represents a step towards a definitive reconstruction of phylogenetic relationships within Old World Elaphe species and describes the revalidation of Coelognathus Fitzinger for Indo-Malayan ratsnakes and the description of a new genus, Oocatochus, for Tropidonotus rufodorsatus Cantor.
Molecular systematics of New World lampropeltinine snakes (Colubridae): implications for biogeography and evolution of food habits
TLDR
The reconstruction of the evolution of food habits among lampropeltinines suggests that a diet emphasizing lizards is ancestral, and therefore diets that mostly consist of mammals, squamate and bird eggs, and snakes are derived within the clade.
Biochemical evaluation of colubrid snake phylogeny
Quantitative biochemical comparisons of albumin differences within the snake family Colubridae were performed, using micro-complement fixation analysis. These tests support the recognition of the
Evolutionary history of the hybridogenetic hybrid frog Rana esculenta as deduced from mtDNA analyses.
TLDR
The preponderance of R. esculenta individuals with lessonae mtDNA in samples from central Europe suggests that most lineages have gone through at least one mating between an R.Esculenta females with R. lessonae males, and reveals a greater reproductive role for R. Esculenta males than their partial sterility and infrequent matings would suggest.
