摘　　要：霍氏缺齿鼩(Chodsigoa hoffmanni)隶属劳亚食虫目(Eulipotyphla)鼩鼱科(Soricidae)缺齿鼩属(Chodsigoa Kastschenko,1907),模式标本来自云南楚雄双柏县,在云南省无量山、哀牢山等地也有发现(Chen et al.,2017)。霍氏缺齿鼩一直被认为是云南缺齿鼩,直到Chen等(2017)使用分子系统学和形态学方法,发现位于澜沧江东西两岸的云南缺齿鼩存在着显著分化,于是将澜沧江东岸的种群描记为新种。In November 2020, three shrew specimens were collected from Mt. Laojunshan, Pingshan County in Sichuan(28°42′08″N, 109°01′58″E, 1 500 m asl) and Shiruguan, Fengjie County in Chongqing(30°38′42″N, 109°29′31″E, 1 857 m asl). Based on morphological characteristics, skull measurement comparison, Kimura-2-parameter distance, and Bayesian phylogenetic tree analysis, these specimens were identified as Chodsigoa hoffmanni, a species previously only known from Vietnam and the Chinese provinces of Yunnan and Hubei. This is the first time that Chodsigoa hoffmanni has been discovered in Sichuan and Chongqing. These records expand the distribution range of Chodsigoa hoffmanni.
