We provide the first molecular phylogenetic data for the following poorly known Northeast Indian snakes: Blythia reticulata and B. hmuifang, Hebius xenura, and Trachischium spp. Based on 1071 bp of cytb, 578 bp of nd4, 509 bp of 16s, 1000 bp of rag1 and 672 bp of cmos, we found support for a monophyletic Blythia being a member of Natricinae, most closely related to Trachischium. Hebius xenura is recovered as nested within species of the recently resurrected genus Herpetoreas, to which we transfer it.
网纹钝头蛇(Blythia reticulata)、黑眉钝头蛇(B. hmuifang)、饰纹小头蛇(Hebius xenura)以及颈棱蛇属(Trachischium spp.)。基于细胞色素b(cytb)的1071个碱基对、烟酰胺腺嘌呤二核苷酸脱氢酶亚基4(nd4)的578个碱基对、16S核糖体RNA(16s)的509个碱基对、重组激活基因1(rag1)的1000个碱基对以及细胞色素氧化酶M(cmos)的672个碱基对,我们发现有证据支持单系的钝头蛇属是水游蛇亚科(Natricinae)的成员,与颈棱蛇属关系最为密切。饰纹小头蛇被归为嵌套在最近恢复的后棱蛇属(Herpetoreas)物种之中,我们将其归入该属。
