Abstract: To explore and clarify the bat species diversity in China, a series of bat surveys were carried out in Hunan Province and Fujian Province. From September 2022 to July 2023, 9 bats (5♂, 4♀) were collected using harp traps in Huaihua and Shaoyang cities in Hunan Province, and in Wuyishan City, Fujian Province. These bats are relatively small, with forearm length ranging from 28. 70 mm to 32. 80 mm, and with black noses and short tube-like nostrils. Dorsal fur has a banded appearance, with a dark gray base, light yellow middle band, and blackish tip. Ventral fur is orange-yellow. Throat fur is banded with a gray-white base and light yellow/orange tip. Their skulls are relatively small, ranging from 15. 15 mm to 16. 39 mm, and exhibit a prominent rostrum, indistinct lambdoid sutures, and lack a sagittal crest. These characteristics are consistent with those of Murina shuipuensis. Phylogenetic analysis based on the Cyt b sequence segment confirmed this identification. The specimens are deposited at the Key Laboratory of Biodiversity Dynamics and Conservation of South China, Guangzhou University, and represent a new bat species record in Hunan and Fujian provinces. Moreover, to predict the potential suitable habitats for M. shuipuensis in China, we applied Ensemble Species Distribution Models (ESDM). We collected 30 distribution points of M. shuipuensis and selected 11 less-correlated environmental variables. The Ensemble function in the R package ‘SSDM’ was used to infer the ensemble model and predict the potential suitable habitats. The performance of the model was evaluated based on AUC and Kappa values. The prediction result was superimposed with distribution points and geographical base map using QGIS to obtain a prediction map of potential suitable areas. We found that the distribution of this species is mainly related to precipitation factors, and tends to be far from human disturbance areas. Regions with high habitat suitability are predominantly located in the mountainous areas of South, East, and Central China, concentrated in northwestern Hunan, northern Guangdong and Guangxi, central to northern Fujian, and central to southwestern Zhejiang. Moderate suitable areas surround the highly suitable area. Overall, suitable areas are closely related to mountains, mainly around Nan Ling, Wuyi Mountains, and Luoxiao Mountains. These predictions could benefit future bat field surveys. The specimens are deposited at the Key Laboratory of Biodiversity Dynamics and Conservation of South China, Guangzhou University presently.

摘要： 为探究并明确中国翼手目物种多样性状况，本课题组于2022年9月至2023年7月，在湖南省怀化市、邵阳市及福建省武夷山市开展翼手目物种多样性调查，使用蝙蝠竖琴网采集到9只(5只雄性，4只雌性)小型蝙蝠。其主要特征为：前臂长28.70~32.80 mm，鼻孔向两侧延长呈“Y”形短管状；背毛从基部至毛尖呈暗灰、浅黄、黑色三色带状；腹毛呈橘黄色，咽部毛基部灰白，毛尖浅黄色到橘黄色；头骨较小，颅全长15.15~16.39 mm，前额吻突显著，矢状嵴和人字嵴均不明显，与水甫管鼻蝠(Murina shuipuensis)的外形及头骨特征相符；同时其Cyt b序列与水甫管鼻蝠的地模标本序列聚为一支。上述形态和分子特征均支持将其鉴定为水甫管鼻蝠，为该种在湖南和福建两省翼手目分布新记录。同时，本研究基于适生区集合物种分布模型(Ensemble SpeciesDistribution Models,ESDM)对水甫管鼻蝠在中国的潜在适生区进行预测，发现该物种的分布与降水因子相关，倾向于远离人类干扰区域，其高适生区主要集中于华南、华东、华中的山脉地段，包括南岭、武夷山系及罗霄山系等，该预测可为后续野外调查提供针对性信息参考。上述标本保存于广州大学华南生物多样性保护与利用重点实验室。
