摘　　要：2022年7月在中国内蒙古自治区的一个矿洞中,用雾网捕获8只(2只雌性,6只雄性)长耳蝠。体型中等,属长耳蝠属体型最大的物种之一,面部裸露,耳大,耳郭和翼膜均为浅棕色微透明状,耳屏较耳郭色浅,背毛棕黄色,腹毛浅灰色至白色。其头骨前额区以及颅顶部有明显的凹陷,具大听泡,齿式为:2.1.2.3/3.1.3.3=36,上颌外门齿和第一前臼齿微小,下颌第二前臼齿略小于下颌第一前臼齿。上述特征与柯氏长耳蝠(Plecotus kozlovi)的特征一致。通过线粒体细胞色素b(Cyt b)基因序列的遗传差异和系统发育分析,支持基于形态学的鉴定。本研究为柯氏长耳蝠在中国的野外活体采集记录和再发现,证实该种现存于中国,丰富了中国翼手目物种记录。In July 2022,eight long-eared bats(consisting of 2 females and 6 males)were captured in a mine in Inner Mongolia,China using mist nets.These bats had a medium body size,in the range of one of the largest species of Plecotus,with mostly naked faces and large ears.Their ear membranes and wings were light brown and slightly transparent.The ear tragus was lighter in color than the ear membrane.The back fur was brownish yellow and the belly fur was light gray to white.Their skulls had a distinct depression in the forehead area and on the top of the head,and a large auditory bullae.The dental formula was 2.1.2.3/3.1.3.3=36,featuring slender canine teeth and tiny upper outer incisors and first premolars,and their lower second premolars were slightly smaller than first premolars.These characteristics are in line with those of Plecotus kozlovi.Genetic differences and phylogenetic analysis based on mitochondrial cytochrome b(Cyt b)gene sequences support the morphological identification.This study constitutes the first field record and rediscovery of P.kozlovi in China,confirming that the species still exists in the country and adding to the country’s bat species records.
