| 中文摘要: |
| 钝头蛇类不同类群在外形、色斑及鳞被特征上有很高的相似度,关于其种属划分长期以来一直存在争议。本文根据已有文献资料及笔者自己的研究成果,主要从形态学和分子系统学方面叙述了钝头蛇类分类学的研究进展,从属以上、属级以及种级分类阶元叙述其研究历史及成果,同时提出了钝头蛇类分类学研究中存在的问题。主要进展如下:①整个亚洲食螺蛇类(钝头蛇类)构成一个科(Pareatidae),而非隶属于游蛇科(Colubridae)的钝头蛇亚科(Pareatinae)；②Aplopeltura,Asthenodipsas为有效属,最大的属Pareas理论上可进一步分为两个属,但需要更充分的的分子系统学与形态学资料验证；③分子系统学研究结果提示Pareas formosensis与P. chinensis不构成单系,应恢复后者的有效性；④综合分类学研究恢复了Asthenodipsas tropidonotus的有效性,并设立新种Asthenodipsas lasgalenensis。 |

| Due to highly conserved morphology, the taxonomy of Asian snail-eating snakes remains contentious and has been frequently revised. Based on the references and our research results,this paper summarizes the studies on the classification of Asian snail-eating snakes in morphology and molecular phylogeny, including affirmation of the family,genus and species. This article lists the geographical distribution of each species of Asian snail-eating snakes too,and bring forward the problems of systematics in these snakes. The main points are as follows: ① The Asian snail-eating snakes should be a separate Family instead of a A Subfamily within Colubridae. ②Aplopeltura and Asthenodipsas are valid genera. Pareas carinatus and P. nuchalis are genetically quite divergent from other species of Pareas, also differ from other Pareas in cephalic scalation and distribution pattern. So, Pareas can be divided into two genera in theory; ③ The molecular phylogeny suggests a distant relationship between Pareas chinensis and P. formosensi, and supports the validity of the former species; ④ The integrative taxonomic approach suggests the validity of Asthenodipsas tropidonotus, and describe Asthenodipsas lasgalenensis as the new species. In conclusion, Pareatidae was recognized to comprise three genera and 17 species: Aplopeltura boa；Asthenodipsas laevis; Asthenodipsas malaccanus; Asthenodipsas vertebralis; Asthenodipsas tropidonotus; Asthenodipsas lasgalenensis; Pareas boulengeri; P. carinatus; P. formosensi; P. chinensis; P. hamptoni; P. iwasakii; P. margaritophorus; P. monticola; P. nuchalis; P. stanleyi; P. nigriceps. |
