| 中文摘要: |
| 2022年7月和9月，本研究组在湖南开展翼手目多样性资源调查时，于常德市桃源县、湘西州保靖县、永州市双牌县和邵阳市绥宁县使用蝙蝠竖琴网分别采集到9只鼠耳蝠(7♂，2♀)和5只管鼻蝠(2♂，3♀)，结合传统形态学和分子系统发育学方法对上述标本进行物种鉴定。该批鼠耳蝠体型中等，前臂长43.41 ~ 50.89mm，全身毛发呈红褐色，耳廓端部、鼻孔周围、五趾与爪及尾末端均呈黑褐色，翼膜掌指间有三角形状的红褐色斑直达翼缘；头骨顶部平缓，颧弓发达，脑颅高而凸显，其形态特征和度量数据均与渡濑氏鼠耳蝠(Myotis rufoniger)相符。同时，采集的管鼻蝠标本体型中等，前臂长33.83 ~ 37.53 mm，背毛棕褐色，腹毛呈浅黄色；颅全长16.74 ~ 17.29 mm，颧弓平直而宽厚，其外形特征和度量数据均与中管鼻蝠(Murina huttoni)相符。基于Cyt b和COI基因构建的系统发育树均支持以上形态学鉴定结果。该报道为渡濑氏鼠耳蝠和中管鼻蝠在湖南省分布的新发现。标本现存于广州大学华南生物多样性保护与利用重点实验室，其中渡濑氏鼠耳蝠标本号为GZHU 22429、GZHU 22430、GZHU 22459、GZHU 22523、GZHU 22961、GZHU 22962、GZHU hun22011、GZHU 22549、GZHU 22703；中管鼻蝠标本号为GZHU hun22001、GZHU hun22008、GZHU 22431、GZHU 22437、GZHU hun22015。 |

| In order to clarify chiropteran resources in Hunan Province, a series of field surveys were conduct in July and September 2022. During our surveys, nine Myotis bats (7 males and 2 females) and five Murina bats (2 males and 3 females) were collected using harp traps in Taoyuan County of Changde City, Baojing County of Xiangxi Prefecture, Shuangpai County of Yongzhou City and Suiling County of Shaoyang City. To identify our sampling, morphological taxonomic analysis and phylogenetic inference were conducted. The Myotis specimens are medium-sized, with forearm length of 43.41﹣50.89 mm (Table 1) and reddish-brown pelage, and blackend edges of ears, nose, toes, claws, and the tail are black-brown (Fig. 1a, c). Triangular reddish-brown spots were presented between the palmar fingers of the wing membrane reaching the edge. The dorsal view of the skull was flat with well-developed zygomatic arch, and the cranial is high and prominent (Fig. 1e). These morphological characteristics and measurements accord with those of Myotis rufoniger. Meanwhile, the Murina specimens were medium-sized, with forearm length of 33.83﹣37.53 mm (Table 1), sepia dorsal hair and light yellow ventral hair (Fig. 2b, c). The greatest length of skull is 16.74﹣17.29 mm (Table 1), and the zygomatic is straight and broad (Fig. 2d, e). These features are consistent with those of Murina huttoni. Based on Cyt b and COI genes segments, our phylogenetic inferences also verified such identifications (Fig. 3). These findings represent the first records of M. rufoniger and Mu. huttoni in Hunan province. Presently, the specimens are deposited in Key Laboratory of Conservation and Application in Biodiversity of South China, Guangzhou University which the M. rufoniger specimens are numbered GZHU 22429, GZHU 22430, GZHU 22459, GZHU 22523, GZHU 22961, GZHU 22962, GZHU hun22011, GZHU 22549, GZHU 22703 andthe Mu. huttoni specimens are numbered GZHU hun22001, GZHU hun22008, GZHU 22431, GZHU 22437, GZHU hun22015. |
