缺齿鼩鼱属Chodsigoa的分类学研究概况

A Summary of Taxonomic Studies on Chodsigoa

缺齿鼩鼱属Chodsigoa由Kastschenko于1907年作为长尾鼩鼱属Soriculus的一个亚属而建立。Thomas于1908年将其提升为属。该属种类主要分布于中国。其属级分类单元争议很大,一些学者认为是独立属,一些学者认为是长尾鼩鼱属的亚属。属下分类方面,不同学者的分类意见也有所不同。其中,Hutterer(2005)将其作为独立属并包括8个种的观点逐步得到大多数人的认可。造成意见分歧的主要原因是以往的系统学研究主要是以形态学研究为主,分子系统学研究较少。

Chodsigoa was initially established as a subgenus of Soriculus by Kastschenko in 1907. Thomas（ 1908） elevated Chodsigoa to a full genus based on craniodental morphology. Most recognized species and subspecies are endemic in China. The taxonomy and systematics of Chodsigoa have been changed in the last 100 years. Hutterer（ 2005） recognized Chodsigoa as a genus and included 8 full species,which has been widely accepted. Most systematics studies were based on morphological comparisons,and few species have been involved in molecular studies.
