西藏自治区发现不丹大鼯鼠和李氏小飞鼠
Petaurista nobilis and Priapomys leonardi found in Xizang Autonomous Region of China
摘要
Abstract
Wildlife photographers and researchers from the Kunming Institute of Zoology,Chinese Academy of Scienc-es,collected specimens and photographs of Petaurista nobilis from Yadong and Cuona County and Priapomys leonardi from Bayi District,Motuo and Cuona County,Xizang Autonomous Region,China between 2022 and 2023.The pelage,skull,and teeth morphology of the P.nobilis specimens resemble those of P.n.singhei Saha,1975,and they form the sister group of Petaurista mishmiensis based on the Cytochrome b gene phylogeny analysis,with the genetic distance of 1.85％.Considering the very small genetic distance,continuous distribution range,and similar habitats between P.nobi-lis and P.mishmiensis,this study recommends that Petaurista mishmiensis be recognized as a subspecies of Petaurista nobilis.The Priapomys leonardi specimens from Xizang are similar to the northwest Yunnan population in terms of pel-age,skull,and teeth morphology.However,they are slightly smaller,and their penis glans differ significantly in length,diameter,and shape.Genetically,the Xizang population is a paraphyletic group including the northwest Yunnan popula-tion,with a relatively small genetic distance(12S ribosomal RNA:0.45％-0.91％,16S ribosomal RNA:0.31％-1.05％).The results presented the first recording of P.nobilis in China and Priapomys leonardi in Xizang Autonomous Region,China,and significantly expands the known range of these taxa,highlighting the need for increased monitoring and research of mammal biodiversity in the Himalayan region.Future surveys in the region will probably discover more new species and records.关键词
