Abstract Polystoma chaochiaoensis from the urinary bladder of the chaochiao frog Rana chaochiaoensis Liu was briefly described in a symposium abstract and presented at the Third Symposium on Parasitology of China in 1990. Types were not assigned and the original specimens collected are no longer available. The morphological description was incomplete and no illustrations were provided. We consider Polystoma chaochiaoensis a nomen nudum and provide a full description for the species and assign types. Based on This article was registered in the Official Register of Zoological Nomenclature (ZooBank) as urn:lsid:zoobank.org:pub: 3EC1C461-7A56-4E6B-86BE-5C91E2F24719. This article was published as an Online First article on the online publication date shown on this page. The article should be cited by using the doi number. This is the Version of Record.

morphological characteristics and molecular data of partial 18S rDNA sequences, we describe this species as Polystoma luohetong n. sp. Out of 578 frogs examined, 16 male and 38 female frogs were infected (prevalence 9.3%; mean intensity 1.02). Polystoma luohetong n. sp. is distinguished from all other Polystoma species by the presense of a prominent crest on the hamulus as well as by the shape and size of marginal hooklets and the intestinal arrangement. Furthermore, the phylogentic analysis based on the 18S rRNA gene shows Polystoma luohetong n. sp. well nested within the Ploystoma clade and as a sister taxon to Polystoma integerrimum.

Introduction Polystomatid flatworms (Monogenea: Polystomatidae Gamble, 1896) are globally distributed and currently there are 27 recognized genera with more than 180 species (Chaabane et al., 2019). The vast majority (19 genera) are known from amphibian hosts. Anuran polystomatids are represented in the Palaearctic realm by species of Diplorchis Ozaki, 1931, Eupolystoma Kaw, 1950, Indopolystoma Chaabane, Verneau & Du Preez, 2019, Polystoma Zeder, 1800, Neoriojatrema Imkongwapang & Tandon, 2010 and Sundapolystoma Lim & Du Preez, 2001. Of these, Diplorchis (6 species), Indopolystoma (6 species) and Polystoma (2 specie
