抄録	We report the first occurrence record of the freshwater ectoparasitic platyhelminth Scutariella japonica (Matjašič, 1990) from Hokkaido, Japan. The flatworms were collected from the surface of exoskeleton and the inside of branchial chamber of the atyid shrimp Neocaridina sp. aff. davidi. Phylogenetic analysis based on the 18S + 28S concatenated dataset of rhabdocoel flatworms retrieved the Scutariella clade, and our specimens identified with Scutariella japonica were genetically distinct from those referred to S. sinensis Chen, Feng, Lin, Lu & Wang, 2018. Phylogenetic analyses using COI showed that the host shrimp specimens from Sapporo were clustered with N. koreana identified by Shih et al. (2017) and placed close to N. palmata (Shen, 1948) and N. davidi (Bouvier, 1904). Our specimens did not agree with the original description of N. koreana Kubo, 1938, particularly in the shape of the endopod of the male pleopod 1. The identity of the present host shrimp specimens could not be established satisfactorily, and thus they were referred to N. sp. aff. davidi for the time being.
