摘　　要：准确的物种鉴定和编目是开展生物多样性保护与管理的前提。莽山位于湖南省南部、湘粤交界处,是南岭生物多样性优先保护区域,具有丰富的两栖动物物种多样性。《湖南动物志两栖纲》记载莽山分布有2种布角蟾属(Boulenophrys)物种:挂墩角蟾(B.kuatunensis)和短肢角蟾(B.brachykolos),但随着角蟾亚科(Megophryinae)系统分类研究的深入,目前这2个物种在莽山的分布存在争议。2021年5—6月、7—8月、11月和2022年6—8月,笔者团队对湖南莽山国家级自然保护区的布角蟾属物种进行了4次实地调查,并采集到20号标本。经形态和分子鉴定,这些标本包括南岭角蟾(B.nanlingensis)、雨神角蟾(B.cf.ombrophila)、九连山角蟾(B.jiulianensis)、石门台角蟾(B.shimentaina),并未发现挂墩角蟾和短肢角蟾。其中,雨神角蟾、九连山角蟾、石门台角蟾为湖南省新记录种。调查结果显示,莽山地区的挂墩角蟾和短肢角蟾记录需要对馆藏标本进一步检视研究。此外,石门台角蟾和南岭角蟾在新种发表时缺乏雌性形态特征描述,本文首次对这2个物种的雌性标本进行了补充描述。Accurate species identification is a prerequisite for biodiversity conservation and management.Mangshan Mountain,located in the south of Hunan and at the border of Hunan and Guangdong provinces,is a priority area for biodiversity protection in Nanling Mountains,with rich diversity of amphibian species.According to the Fauna Hunan:Amphibia,there are two Boulenophrys species distributed in Mangshan:B.kuatunensis and B.brachykolos,but with the further study of the systematic classification of subfamily Megophryinae,the distribution of the two species in Mangshan is currently controversial.During May to June,July to August,November 2021 and June to August 2022,four field surveys on the species of Boulenophrys in Mangshan National Nature Reserve,Hunan Province were conducted,and 20 specimens were collected.Through morphological and molecular identification,these specimens proved to belong to four species:B.nanlingensis,B.cf.ombrophila,B.jiulianensis,and B.shimentaina,and the latter three species are new records in Hunan Province.However,the species B.kuatunensis and B.brachykolos were not found to exist in Mangshan.Therefore,the existence of the two species in Mangshan should be further confirmed.In addition,the morphological characteristics of female B.shimentaina and B.nanlingensis were described for the first time,which were lack in the original new record description.
