摘　　要：2014年4月在广东封开黑石顶千层峰粉单竹Bambusa chungii竹林内采集到10只小型蝙蝠,其体重为3.0～4.4 g,前臂长为24.6～26.6 mm;背毛深棕褐色,腹部毛色略浅,大拇指基部和足掌具肉垫;头颅骨扁平.经鉴定为褐扁颅蝠Tylonycteris robustula,是广东省境内首次采集发现.该新记录使褐扁颅蝠在华南地区的分布呈现连续状态.文章还对该种在中国分布区及可能地理分布范围进行了探讨.10 vespertilionids specimens are collected at Bambusa chungii bamboo forest of Heishiding provincial nature reserve from Fenkai County,Guangdong Province in April 2014.Main characteristics of the specimens are as follow;small size,light weight 3.0 ～4.4 g,forearm length 24.6-26.6 mm,well-developed pads at the bases of the thumbs and hindfeet,dark brown fur above but slightly paler fur below,and extremely flattened skull.According to these characteristics,they are identified as T.robustula.They represent a new record in Guangdong Province,China.Owing to this new record,the distribution area of Chinese T.robustula becomes continuous instead of discrete.Moreover,their potential demotic distribution area is also discussed in this study.
