广东省缺齿鼩属新纪录——高氏缺齿鼩
The first record of Chodsigoa in Guangdong Province:Chodsigoa caovansunga
摘要
Abstract
In 2019,a shrew specimen(GIZ:2019099)was collected from Yunkai Mountain in Xinyi,Maoming City,Guangdong Province(22.267 052 8°N,111.197 391 7°E,elevation 1 025 m).Morphological identification indicated that this specimen exhibited typical characteristics of the genus Chodsigoa.Evolutionary analysis based on cytochrome oxidase I(COI)gene sequences on mitochondrion confirmed that this specimen clustered with Chodsigoa caovansunga,marking the first record of this genus in Guangdong Province.The specimen is a subadult with a domed cranium and unfused pari-etal and interparietal bones,which differs from the known specimens of C.caovansunga.Additionally,phylogenetic analyses revealed the presence of C.caovansunga in Libo,Guizhou Province.In recent years,several small mammal spe-cies known only from Southeast Asia have been discovered in Guangdong Province,suggesting the existence of a migra-tion corridor for small mammals between Vietnam and Guangdong Province.关键词
