A monogenean was discovered parasitizing the bladder of Hylarana maosonensis, an amphibian species that was not previously recorded in Yunnan Province, China. Through numerical taxonomy and comparative analysis, the monogenean was identified as a previously undescribed species of the genus Diplorchis within the family Polystomatidae and was named as Diplorchis yunnanensis Fan & Meng, sp. nov. Detail descriptions and illustrations are provided. The typical materials are deposited in the School of Life Sciences at Yunnan Normal University.
