广东兽类新纪录——湄公白腹鼠
The first record of Niviventer mekongis in Guangdong
摘要
Abstract
In field surveys conducted in February and November 2023 in Yunkaishan,Xinyi County,Maoming,Guangdong Province(22°16′1.39″N,111°11′50.61″E,altitude 1 025 m)and the Xianrendong Scenic Area(22° 16′39.08″N,111°15′24.43″E,altitude 1 146 m),one adult and one juvenile specimens of Niviventer were captured.Morphological analysis revealed that these two specimens have longer rostrums,tail lengths,and hindfoot lengths com-pared to Niviventer huang,and lack yellowish-brown spots on their chest fur,aligning with the characteristics of Niviven-ter mekongis.The maximum likelihood tree constructed based on mitochondrial Cyt-b gene sequences showed that the two specimens clustered with Niviventer mekongis,and the node support rate was 100%.These findings provide strong evidence that the specimens belong to Niviventer mekongis,representing a new distribution record and the third recorded species of the Niviventer genus in Guangdong.关键词
