摘要/Abstract

摘要： 2022—2023年，摄影爱好者和中国科学院昆明动物研究所科研人员先后在西藏自治区拍摄和采集到不丹大鼯鼠(Petaurista nobilis)(错那县、亚东县)和李氏小飞鼠(Priapomys leonardi)(巴宜区、墨脱县和错那县)的照片及标本。研究发现不丹大鼯鼠西藏种群形态上与不丹大鼯鼠不丹亚种(Petaurista nobilis singhei Saha, 1975)的描述一致；遗传上与米什米大鼯鼠(Petaurista mishmiensis)构成姊妹群，遗传距离较小(Cyt b:1.85%)。考虑到不丹大鼯鼠和米什米大鼯鼠之间的遗传差异过小，分布区连续且栖息地都为中低海拔的常绿阔叶林，故两者应视为同一物种；又因两者之间的毛色差异稳定存在，可作为不同亚种，根据优先律，使用不丹大鼯鼠Petaurista nobilis(Gray, 1842)做为种名，米什米大鼯鼠降为不丹大鼯鼠米什米亚种(Petaurista nobilis mishmiensis Choudhury, 2009)。李氏小飞鼠西藏种群毛色、头骨和颊齿特征与云南西北部种群一致，但体型较小，且阴茎长度、直径和形状有较大程度的变异；遗传上西藏种群是包含云南西北部种群的并系群，遗传距离较小(12S ribosomal RNA:0.45%~0.91%, 16S ribosomal RNA:0.31%~1.05%)。不丹大鼯鼠为中国兽类新纪录，李氏小飞鼠为西藏自治区兽类新纪录。本研究扩展了不丹大鼯鼠和李氏小飞鼠的分布区，提示应进一步加强喜马拉雅地区兽类的调查与监测研究工作，以发现更多的新物种、新纪录。

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. nobilis 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.
