Abstract
On the basis of inter-simple sequence repeat (ISSR) loci and the nucleotide sequences of nuclear (18S and ITS-1) and mitochondrial genes (COI and 16S), a phylogenetic analysis of the three species of terrestrial mollusks of the family Bradybaenidae (Mollusca, Pulmonata), Bradybaena fruticum Müll., Bradybaena schrencki Midd., and Bradybaena transbaicalia Shileyko, was conducted to clarify their taxonomic status. The analysis showed that Br. fruticum was far apart from the other two species (Br. schrencki and Br. transbaicalia). The genetic distance between the latter puts in doubt their status as distinct species. It is suggested that the species Br. transbaicalia can be treated as a form of Br. schrencki var. transbaicalia.
基于简单序列重复(ISSR)位点、核基因(18S和ITS-1)和线粒体基因(COI和16S)的核苷酸序列，对慢贝科(软体动物，Pulmonata) 3种陆生软体动物慢贝纳(Bradybaena fruticum m ll.)的系统发育进行了分析。布拉迪巴纳施伦基Midd。为明确其分类学地位，对其进行了研究。分析表明，Br。fruticum与其他两种(Br。schrencki和Br。transbaicalia)。后者之间的遗传距离使它们作为不同物种的地位受到怀疑。认为Br。transbaicalia可以看作是Br的一种形式。横贯北大西洋的施伦氏变种。
