Abstract
The complete mitochondrial cytb gene and the partial nuclear c-mos gene of Oligodon ningshaanensis Yuan, 1983 were sequenced and used for reconstructing the phylogenetic relationship of this taxon amongst alethinophidian snakes. Its strong affinity to the New World subfamily Dipsadinae and the Old World species Thermophis baileyi was inferred. Hemipenial morphology found by authors conflicts with the original description and its similarity with those of the dipsadid snakes is in accordance with our molecular results. Feeding tests show that O. ningshaanensis is a malacophagous predator, which is another matchless character for this species. This behavior is described and compared with other known slug- and snail-feeding snakes. The discovery of the particular position of our subject indicates that erecting a new genus is necessary accommodate this unique species.
期刊介绍：
AHR aims to provide a forum for herpetologists and related scientists interested in conducting international academic exchanges and joint studies, and a platform for introducing their newly made scientific and technological data, and publishing their research results and achievements in the world, but focusing on the Asian-Pacific Region.
The principal criteria of AHR for acceptance of articles for publication are the quality and significance of the research, breadth of interest of the work to the readership, and the clarity and effectiveness of communication. AHR welcomes submission of manuscripts from authors in all countries of the world, though with a focus on the herpetological studies in the Asian and Pacific Region, including major articles, shorter communications and review articles.
