水蛇亚科属于游蛇科,包含10个属.其中7个属为单型属.选取水蛇亚科14个形态学特征进行支序分析,并利用计算机软件Hennig 86对水蛇亚科中8个属之间的系统发育关系进行初步探讨,结果显示水蛇亚科分为两支:Gerarda和Fordonia两个属构成姊妹群,Cerberus、Erpeton和Homalopsis三个属也构成单系群,与Voris et al(2002)的分子系统树相同,但Cantoria属的地位则与Voris et al(2002)的明显不同.

The morphological phylogeny of the water snake subfamily Homalopsinae, containing 10 genera, of which seven are monotypic, was not reported up until now. Here fourteen morphological characters were selected for the cladistic analysis. Using software Hennig 86, two phylogenetic trees were inferred and the results showed that the subfamily Homalopsinae was divided into two groups. Compared with the molecular phylonenetic tree of Voris et al (2002), the genera Gerarda and Fordonia are sister groups in both studies; both studies also yielded the same monophyletic lineage, which contained three genera ( Cerberus + Erpeton + Homalopsis ). However, the position of the genus Cantoria is distinctly different with the study of Voris et al(2002).
