大墓蝠在广东省分布的再发现

<正>鞘尾蝠科(Emballonuridae)墓蝠属(Taphozous)在全世界共有14种(Wilson and Mittermeier, 2019)，分布在赤道与南北回归线之间的热带和亚热带地区(Kitchener et al., 1993)。该属在我国仅分布2种，即黑髯墓蝠(Taphozous melanopogon)和大墓蝠(Taphozous theobaldi)，前者主要分布于广东、广西、云南、贵州、海南、澳门和香港(蒋志刚等，2015)，为广布种；后者文献记录甚少，标本稀缺，

Rediscovery of Theobald's tomb bat (Taphozous theobaldi,Chiroptera, Emballonuridae) from Guangdong,China

A series of tomb bats were captured in a cave by using harp traps in Longmen County, Guangdong Province, China (23o35'18″N, 114o17'53″E, 91 m a. s. l.), between 2007 and 2020. The bats were similar in appearance but of different sizes. Six of them are morphologically and morphometrically similar to Taphozous theobaldi rather than Taphozous melanopogon. Both principal component analysis and discrimination analysis suggested the separation between T. theobaldi and T. melanopogon. T. theobaldi exhibits an elongated posterior orbital process and a well-developed pterygoid bone. Such identifications are also supported by the phylogenetic inferences using a segment of of Cyt b mitochondrial gene. Given that no traceable T. theobaldi specimens were reported since the first records in 1984, our finding represents the field rediscovery of this species after nearly 40 years.
