Description and phylogeny of three new species of Synophis (Colubridae, Dipsadinae) from the tropical Andes in Ecuador and Peru
The discovery of three new species of Synophis snakes from the eastern slopes of the tropical Andes in Ecuador and Peru is reported. All previous records of Synophis bicolor from eastern Ecuador correspond to Synophis bogerti sp. n., which occurs between 1000-1750 m along a large part of the Amazonian slopes of the Ecuadorian Andes. In contrast, Synophis zamora sp. n. is restricted to southeast...
متن کاملA new species of cat snake (Reptilia: Serpentes: Colubridae: Boiga) from dry forests of eastern Peninsular India.
A new species of cat snake, related to Boiga beddomei (Wall, 1909), is described from the dry forests of eastern Peninsular India. It occupies a large geographic range from Berhampore (type locality), near the River Mahanadi in the northeast to Kaigal near the southern Eastern Ghats in the southwest. The new species is diagnosed by having the following combination of characters: 19 dorsal scale...

Received 15 August 2005. Accepted 21 November 2005. Distributed December 2005. Abstract Body size, reproductive biology and abundance of the rare pseudoboini snakes genera Clelia and Boiruna (Serpentes, Colubridae) in Brazil. Pseudoboini snakes of the genera Clelia and Boiruna are apparently rare in nature and certainly rare in collections. This work presents data on body size, reproduction and...
متن کاملStudy of Blood Parasites of the Three Snake Species in Iran: Natrix natrix, Natrix tessellata and Zamenis longissimus (Colubridae)
Infections with blood parasites are common phenomenon in reptiles from all over the world. Apicomplexan are the majority of blood parasites that frequently occur with high levels of parasitaemia in the snakes. The aim of this study was to determine the presence of blood parasites in some snakes Guilan province in the North of Iran. A total of 51 specimens of three snake species were captured in...
متن کاملThe phylogeny of advanced snakes (Colubroidea), with discovery of a new subfamily and comparison of support methods for likelihood trees.
The superfamily Colubroidea (> 2500 species) includes the majority of snake species and is one of the most conspicuous and well-known radiations of terrestrial vertebrates. However, many aspects of the phylogeny of the group remain contentious, and dozens of genera have yet to be included in molecular phylogenetic analyses. We present a new, large-scale, likelihood-based phylogeny for the colub...
