Abstract

ABSTRACT. The mitochondrial cytochrome b and nuclear ApoB and RAG2 genes were used to estimate the phylogenetic relationships in Asiatic red-toothed shrews (Soricidae, Episoriculus). Based on molecular data, the genus Episoriculus seems to consist of at least seven valid species: E. baileyi, E. caudatus, E. leucops, E. macrurus, E. sacratus, E. soluensis, and E. umbrinus. Genetic distances among all of them are found to be of 8–16%, with the only low distance (3.4%) being that between E. baileyi and E. leucops. Taiwanese shrew E. fumidus shows high genetic divergence (16–17% for cytb) from other species of Episoriculus. Based on both genetic and morphological data it should be attributed to a separate new genus Pseudosoriculus gen.n. Episoriculus umbrinus was found in Lao Cai Province, representing a new species record for the fauna of Vietnam; morphology-based diagnosis of this specimen has reliably been confirmed by molecular data.

越南的第一个记录，并对其分类组成进行了说明（哺乳动物，Soricidae）

摘要。利用线粒体细胞色素b、细胞核ApoB和RAG2基因来估计亚洲红齿鼩（Soricidae，Episoriculus）的系统发育关系。根据分子数据，Episoriculus属似乎至少由七个有效物种组成：E.baileyi、E.caudus、E.leucops、E.macrurus、E.sacratus、E.soluensis和E.umbrinus。发现它们之间的遗传距离为8-16%，唯一较低的距离（3.4%）是E.baileyi和E.leucops之间的距离。台湾鼩（E.fumidus）与其他物种的Episoriculus表现出高度的遗传差异（cytb为16-17%）。根据遗传学和形态学数据，它应归属于一个单独的新属Pseudosoriculus gen.n。Episoriculs umbrinus在老蔡省被发现，代表了越南动物群的一个新物种记录；分子数据已经可靠地证实了该标本基于形态学的诊断。如何引用这篇文章：Abramov A.V.，Bannikova A.A.，Chernetskaya D.M.，Lebedev V.S.，Rozhnov V.V.2017。来自越南的第一个记录，附关于Episoriculus（哺乳动物，Soricidae）分类组成的注释//俄罗斯J.Theriol。第16卷第2期。P.117–128.doi:10.15298/rusjtheriol.6.2.01
