On October 23, 2022, a mole specimen (GZHU: SG220601) was collected in Renhua County, Shaoguan City, Guangdong Province (113°40′30. 12″E, 25°11′15. 75″N, altitude 177 m). The skull of this specimen has a wide snout and a relatively forward auditory bulla. It has three lower incisors, and the posterolingual edge of P4 is deeply concave and V-shaped. These morphological characteristics are consistent with those of Euroscaptor kuznetsovi. A maximum likelihood (ML) tree constructed using mitochondrial CYTB confirms that this specimen belongs to the E. kuznetsovi clade (support rate 81%) and is closely related to specimens from Jiangxi and Zhejiang (support rate 100%). The genetic difference between SG220601 and topotype specimens is approximately 4. 1% (p-distance), while the difference between SG220601 and specimens from Jiangxi and Zhejiang is about 1. 4% (p-distance). The above evidence supports the identification of SG220601 as E. kuznetsovi, representing the first record of this species in Guangdong Province and the second Talpid mole species recorded in the region.
