摘　　要：采用DNA测序方法,获得了中国狼蛛科Lycosidae4亚科6属26种mtDNA-16SrRNA基因的部分序列,比较来自北美狼蛛科豹蛛属2种豹蛛的同一基因序列,并选取漏斗蛛科1种蜘蛛作为外群,采用Bayesian方法和最大简约法(MP)构建分子系统树。两种建树方法均支持娲蛛属和豹蛛属形成一大的单系;这一结果与现行狼蛛科传统分类体系中娲蛛属的分类地位有差别。据此,作者认为:娲蛛属和豹蛛属可以归为同一个分类亚单位。狼蛛科6属间的分子系统关系为(Pirata(Hippasa(Trochsa+Arctosa(Pardosa+Wadicosa))))。The mtDNA-16S rRNA gene partial sequences were amplified and sequenced from 26 species representing 4 subfamilies and 6 genera of Lycosidae in China.Aligning with 16S rRNA sequences of 2 species（Pardosa Lycosidae）in North America from GenBank,and selecting 1 species Agelena limbata（Agelenidae）as outgroup from China,we constructed a matrix of 29 DNA sequences.The phylogenetic trees of the Lycosidae were constructed by using the method of Bayesian and Maximum Parsimony（MP）.The results indicate that Wadicosa has the closest phylogenetic relationship with Pardosa.Pardosa and Wadicosa form a monophyletic group and this result supported that the two genera should be merged into one subfamily.the molecular phylogeny of 6 genera of Lycosidae is（Pirata（Hippasa（Trochsa＋Arctosa（Pardosa＋Wadicosa））））.
