广东省翼手目新纪录——宽耳犬吻蝠及其回声定位叫声特征

A New Record of Tadarida insignis in Guangdong Province,China and Characteristic of Its Echolocation Calls

2013年6月和9月在广东省英德市郊碧落洞（24°06＇56.9＇＇N,113°21＇10.0＇＇E,海拔88 m）分别捕捉到5号和1号蝙蝠标本（均为雌性）。上述蝙蝠体型较大,前臂长60.4～63.3 mm,胫骨长18.0 mm,颅全长24.8 mm,颅基长23.9 mm;耳大,双耳前基部在额部相联,上唇肥厚且具24～26个硬瘤,尾从尾膜后缘伸出一半,毛色土褐,双色;颅骨大,腭缘缺刻深,长大于宽。经鉴定为宽耳犬吻蝠Tadarida insignis,为广东省翼手目新纪录。本文给出了宽耳犬吻蝠的外形和头骨特征,并与来自安徽、山东和日本的标本进行了对比;同时对其回声定位信号进行了分析。标本保存于广东省昆虫研究所。

Six female bats（ Tadarida insignis） were collected from the Biluo Cave（ 24°06′56. 9″N,113°21′10. 0″E,88 asl.）,Yingde city,Guangdong province in June and September,2013. T. insignis was a relative large bat,with forearm length 60. 4 ～ 63. 3 mm,tibia length 18. 0 mm,greatest length of skull 24. 8 mm,condylobasal length 23. 9 mm. The ears were very large and joined at their anterior bases,upper lip thickly set with horny excrescences about twenty-four to twentysix,the terminal half tail extended beyond the membrane. The fur was drab and had two colours. The skull was large,palatal emargination deep,and the length was longer than wide. It was the first record for T. insignis in Guangdong province. In this paper,we provided the feature of morphological structure and skull of the specimens,and compared with the specimens from Anhui,Shandong and Japan. The echolocation calls of these bats were also analyzed. The specimens were kept in Guangdong Entomological Institute.
