摘　　要：报道了角蟾科一新亚种,该亚种具角蟾属特征,与峨眉角蟾种组中的炳灵角蟾(Megophrysbinlingensis)形态特征最为相近,但与该组成员又有明显区别,被命名为炳灵角蟾梵净山亚种(M.b.fanjingmontis subsp.nov.)。本亚种主要鉴别特征为犁骨棱较弱,后端无犁骨齿,上颌有细齿;第一、二指上婚刺细密,趾侧缘膜窄;体腹面斑少,两侧黑褐色长形斑明显;体型较大,雄性头体长大于60.00 mm;趾间具1/3蹼。This paper describes a new subspecies of Megophryidae from Guizhou Province, China, which has typical characteristics of Megophrys omeimontis group of the genus Megophrys,however,it is also distinguished from other species of this group in morphology. The new subspecies is named as M. binlingensis fanjingmontis subsp, nov. , owing to more similarity to M. binlingensis of M. omeimontis group in morphological character. Holotype： No. trxy01, adult male; collected from Heiwan River region in Fanjing Mountain of Jiangkou County, Guizhou Province in June,2010. Altitude ： about 900m. Allotype： No. trxy02, adult female; collected from Heiwan River region in Fanjing Mountain of Jiangkou County, Guizhou Province. Paratype ： No trxy03, trxy04 ,trxy05, adult male; collected from Heiwan River region in Fanjing Mountain of Jiangkou County,Guizhou Province. All specimens are kept in Animal Laboratory of Bioscience and Chemistry Department,Tongren University. Diagnosis： This subspecies can be distinguished by the following characters： vomerine ridge is tinny, without vomerine teeth,and slender teeth grow on upper jaw; nuptial spinules are small and dense on the first two fingers of males; narrow film displays at the edge of outside toes; few spots scatter on chest and belly, marked dark brown strips occur on the both sides of chest and belly; body is big,SVL 〉 60.00 mm; 1/3 web exit between toes. However, compared with the new subspecies,the adult males of M. binlingensis are smaller,45.0 mm〈 SVL 〈 51.0 mm. and their web trace exist between toes. M. spinata differs from the new subspecies in the following characters： nuptial spinules of M. spinata are bigger and sparser on the first two fingers of males; markedly wide film at the edge of outside toes, 1/2 web between toes; 47.2 mm 〈 SVL （males） 〈 54.4 ram; more than ten dark spots on chest and belly. However, our new subspecies have five, six, or seven dark spots on chest and belly, without spot in the middle of belly. For M. omeimontis,its v
