爪哇伏翼在广东分布的新记录

A New Record of Pipistrellus javanicus(Chiroptera:Vespertilionidae)from Guangdong Province

为调查广东石门台国家级自然保护区翼手目多样性情况,于2019年9月使用雾网采集到一批蝙蝠,其中5只伏翼(1♂、4♀)体型小,前臂长27.7~30.5 mm。头部及耳朵呈深棕色;被毛较密,背毛暗棕色,腹毛稍浅,基部褐色,毛尖灰白色;后足长约为胫骨长的一半,翼和尾膜深棕色;头骨粗壮,吻突宽平;颧弓窄而短,无眶上突,矢状嵴和人字嵴微弱;齿式:2.1.2.3/3.1.2.3=34。上述标本与爪哇伏翼Pipistrellus javanicus的外形及头骨特征相符。基于COⅠ基因序列的系统发育分析也支持形态学鉴定结果。本发现为爪哇伏翼在广东省分布的新记录,标本保存于广东省科学院动物研究所。

To investigate the diversity of Chiroptera in the Shimentai National Nature Reserve,Guangdong Province,a batch of bats were collected by mist nets in September 2019.Among the collected bats,5 Pipistrelle bats(1♂,4♀)are small body size,forearm length of 27.7-30.5 mm.The head and ears are dark brown.The coat is dense and the back hair is dark brown.The abdominal hair is slightly lighter than the back hair.The base hair color is brown and the hair tip is gray white.The hind-foot length is about half of the tibia length.The wings and tail membranes are dark brown.The skull is stout and the snout is wide and flat.The zygomatic arch is narrow and short.No supra-orbital process.Sagittal and herringbone ridge is very weak.The dental formula is 2.1.2.3/3.1.2.3=34.These external and skull characteristics are consistent with those of Pipistrellus javanicus.Phylogenetic analysis based on COⅠ gene sequence also supported the above morphological identification result.This study represents a new chiropteran record in Guangdong Province,China.The specimen is kept in the Institute of Zoology,Guangdong Academy of Science.
