We sampled snakes of the genus Xenochrophis from across Northeast India. The snakes were evaluated for both morphological and molecular parameters. Phylogenetic relationship was reconstructed using mitochondrial genes (Cytb, 12s rRNA, ND4). The genus Xenochrophis was found to be paraphyletic, X. piscator complex and X. punctulatus form a single clade with Atretium schistosum as their sister taxon. X. cerasogaster forms a distinct lineage. X. vittatus and X. trianguligerus are related to the genus Rhabdophis. Herein it is recommended that X. piscator complex, i.e. X. asperrimus, X. flavipunctatus, X. melanzostus, X. piscator, X. sanctijohannis, X. schnurrenbergeri and X. tytleri, as well as X. punctulatus be reallocated to the genus Fowlea.
我们从印度东北部各地采集了渔游蛇属的蛇类。对这些蛇进行了形态学和分子参数评估。利用线粒体基因(细胞色素b、12s核糖体RNA、ND4)重建了系统发育关系。结果发现渔游蛇属是并系的,渔游蛇复合种和斑渔游蛇形成一个单系分支,以拟腹链蛇作为它们的姐妹分类单元。腹斑渔游蛇形成一个独特的谱系。饰纹渔游蛇和三角渔游蛇与颈槽蛇属有关。在此建议将渔游蛇复合种,即糙渔游蛇、黄斑渔游蛇、黑斑渔游蛇、渔游蛇、圣约翰渔游蛇、施氏渔游蛇和泰勒氏渔游蛇,以及斑渔游蛇重新归入福勒蛇属。
