西藏自治区两种蝙蝠新纪录:安氏长舌果蝠和艾氏管鼻蝠OA北大核心CSTPCD

In October 2020 and December 2023,two bat specimens were collected in Medog County,Xizang Autonomous Region.Among them,one male specimen is medium in size,with small ears,non-protruding nostrils,and an elongated muzzle.The skull is small and elongated,with a narrow zygomatic width,a pronounced downward turn of the occiput,pointed upper canines,and two pairs of smaller upper and lower incisors,which is consistent with the characteristics of Macroglossus sobrinus.The maximum likelihood tree constructed based on COI gene showed that it was clustered with M.sobrinus specimes,and the genetic distance between them was 0.6％,which supported it to be M.sobrinus.The other specimen is a female with dark yellowish-brown dorsal fur with metallic luster,grayish-white ventral fur,and grayish-black hair bases.The wing membranes are black,the ears are nearly ovoid,and the nasal muzzle protrudes as a short tube,which is consistent with the characteristics of Murina eleryi.Phylogenetic analysis based on the COI gene showed that it was clustered with M.eleryi individuals,which supported it to be M.eleryi.Both M.sobrinus and M.eleryi represent new records for Xizang.
