Abstract
In 2018, an adult male of a small-sized Tube-nosed Bat (Chiroptera: Vespertilionidae: Murina) was captured at an arid cave located on the Qinghai–Tibet Plateau in Yushu City, Qinghai Province, China. Despite external morphological similarities with those of M. harpioloides and M. chrysochaetes, the individual in question displays explicit craniodental differences that distinguish it from either species. Morphological and morphometric evidence, coupled with phylogenetic analyses utilizing the mitochondrial COI gene, confirmed that it represents a distinct and still unknown species of Murina, described herewith as M. yushuensis sp. nov. Our research highlights the importance of future surveys aimed at exploring cryptic species diversity in the Qinghai–Tibet Plateau and adjacent under-surveyed regions.

本研究于2018年在中国青海玉树1个河流旁的干燥洞穴中捕获1只雄性小型管鼻蝠（翼手目Chiroptera：蝙蝠科Vespertilionidae：管鼻蝠属Murina）。其主要特征为，前臂长31.34 mm，颅全长14.14 mm；耳小而圆，无缺刻；背毛呈现基部黑色，顶端为棕金色；腹毛基部较长，呈深黑色，顶部呈灰白色。基于形态学证据和COI构建的系统发育树，本研究将其鉴定为管鼻蝠属的新物种，命名为玉树管鼻蝠（Murina yushuensis sp. nov. Han, Csorba et Wu, 2024）。该发现不仅丰富了翼手目物种多样性，还说明了在青藏高原及周边区域等特殊生境开展翼手目调查的重要性。 || 形态度量学, 管鼻蝠亚科, 系统发育关系, 系统学, 分类学
