亚洲食螺蛇（学名：Pareas）是亚洲食螺蛇科（Pareidae）中最大的一个属，广泛分布于东南亚。然而，由于其高度保守的形态和不完整的样品，潜在的多样性仍然很少探索。在此，更广泛的采样的基础上，种间系统发育关系的属Pareas重建使用两个线粒体（片段（cyt B和ND 4）和两个核基因（c-mos和RagI），和外部形态数据进行多变量形态计量学。贝叶斯推断和最大似然分析一致表明，属Pareas是由两个不同的，单系的支持值从中等到低。根据分子系统学和形态学资料，揭示了该属植物的潜在多样性，并描述了两个新种。此外，还证实了斑点P. macularius的有效性。
The Asian snail-eating snakes Pareas is the largest genus of the family Pareidae (formerly Pareatidae), and widely distributed in Southeast Asia. However, potential diversity remains poorly explored due to their highly conserved morphology and incomplete samples. Here, on basis of more extensive sampling, interspecific phylogenetic relationships of the genus Pareas were reconstructed using two mitochondria( fragments (cyt b and ND4) and two nuclear genes (c-mos and RagI), and multivariate morphometrics conducted for external morphological data. Both Bayesian Inference and Maximum Likelihood analyses consistently showed that the genus Pareas was comprised of two distinct, monophyletic lineages with moderate to low support values. Based on evidences from molecular phylogeny and morphological data, cryptic diversity of this genus was uncovered and two new species were described. In additional, the validity of P macularius is confirmed.
