| 中文摘要: |
| 2023年6月12日，在湖南省城步县南山国家公园(110°11′42″ E，26°11′54″ N)采集到无尾目(Anura)角蟾科(Megophryidae)布角蟾属(Boulenophrys)雌性标本1号(标本号NS20230612)，现保存于湖南师范大学生命科学学院脊椎动物学实验室。该标本背部皮肤光滑有痣粒，两侧皮肤松弛，有刺疣，背部灰褐色，背中央有深色“X”形斑，与花坪角蟾(B. mirabilis)形态鉴别特征一致。基于线粒体16S rRNA和COI基因片段进行的系统发育分析结果显示，该标本与花坪角蟾聚为一支；平均遗传距离为0.28%，远小于布角蟾属物种间的遗传距离。结合形态特征比较与系统发育关系重建，鉴定该标本为角蟾科布角蟾属花坪角蟾，查阅相关文献资料，确认花坪角蟾为湖南省两栖纲分布新记录种。该物种的发现丰富了南山国家公园的两栖爬行动物物种多样性，同时为该物种分类及谱系地理学研究提供了参考资料。 |
| 英文摘要: |
| The Asian horned toad genus Boulenophrys within the family Megophryidae, is a typical representative for Oriental fauna, spreading throughout southern China, southern and eastern Himalayas, across Indochina to islands of the Sunda Shelf and the Philippines.On June 12, 2022, during the investigation of amphibian and reptile resources in Nanshan National Park of Chengbu County, Hunan Province, a female specimen (Voucher No. NS20230612) of the genus Boulenophrys, Megophryidae of Anura was collected (110°11′42″ E, 26°11′53″ N) and deposited in the Vertebrate Zoology Laboratory, College of Life Science, Hunan Normal University.The specimen was identified by morphological measurements and phylogenetic analysis based on two mitochondrial genes, namely partial 16S ribosomal RNA gene (16S rRNA) and partial cytochrome c oxidase I gene (COI). The 16S rRNA and COI gene sequences of some Boulenophrys species were also downloaded from GenBank (Table 1). According to the morphological characteristics, the back of the specimen was smooth with moles, the skin on both sides was loose, the warts were spiny, the back was grayish brown, there were dark “X” spots in the center of the back (Fig. 1). It is consistent with the morphological identification characteristics of B. mirabilis collected from Huaping Nature Reserve in Guangxi. The results of phylogenetic analysis based on 16s rRNA and COI gene fragments showed that the collected sample was clustered with B. mirabilis in one branch (Fig. 2). Combined the morphological characteristics and the reconstruction of phylogenetic relationship, the collected specimen was identified as B. mirabilis, which is a new record of amphibian in Hunan Province. The discovery of this species not only increases the species diversity of amphibians in Nanshan National Park, but also provides a reference for the taxonomy and pedigree geography of this species. |
