【摘要】 <正>哺乳动物（亦称兽类）是地球上结构、功能和行为最复杂的一个高等动物类群，对生态系统的功能和稳定有着重要的影响。缺齿鼩属（Chodsigoa Kastchenko,1907）隶属于哺乳纲劳亚食虫目（Eulipotyphla）鼩鼱科（Soricidae），是一类体型较小，体质量一般不超过10 g，体长短于10 cm的小型食虫类哺乳动物（Wilson and Mittermeier,2018）。缺齿鼩属物种常栖息于海拔1 000 m以上、人为干扰较少、气候湿润的山地森林中，野外调查相对困难，生物学资料十分匮乏（Chen et al.,2017;Wilson and Mittermeier,2018）。更多还原

【Abstract】 In November 2023, a shrew specimen was collected from Chun’an County, Hangzhou City, Zhejiang Province.This small shrew has dark gray dorsal fur and weighs 5.75 g.It has a head-body length of 65 mm, with a tail shorter than the head-body length.It features three upper unicuspid teeth with lightly pigmented red on the tips of incisors and unicuspids premolars, indicating that it belongs to the genus Chodsigoa.This represents the first record of Chodsigoa in Zhejiang Province.Through phylogenetic analysis of mitochondrial Cyt b sequences, this specimen was recovered as sister to a clade containing C.dabieshanensis, C.hypsibia, and C.parva.The genetic distances between this specimen and the three species are 8.33%, 8.90%, and 9.53%, respectively.Further research is needed to clarify the taxonomic status of this specimen.更多还原
