Helminths from Eumeces latiscutatus (n = 17) and Takydromus tachydromoides (n = 34) from Japan are reported. Two species of Nematoda, Kurilonema markovi and Meteterakis japonica, and 1 taxon of Acanthocephala, cystacanths of Centrorhynchus sp., were found in E. latiscutatus; 1 species of Digenea, Plagiorchis taiwanensis, and 2 species of Nematoda, K. markovi and Oswaldocruzia filiformis, were found in T. tachydromoides. Oswaldocruzia yezoensis is proposed as a synonym of Oswaldocruzia filiformis. Takydromus tachydromoides represents a new host record for P. taiwanensis and Japan is a new locality record.
