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.
