The helminth fauna of the moor frog Ranaarvalis Nilsson, 1842, from the Volga river basin has never been reviewed before (Russia). The helminthic fauna of this species is discussed in the article together with data from the literature and the authors. Complete helminthological dissection was the technique used. Three groups of helminths—Cestoda (class 1), Trematoda (class 28), and Chromadorea—accounted for 38 different species (9). Nine helminth species, including the trematodesGorgoderavarsoviensisSinitzin, 1905, StrigeafalconisSzidat, 1928, Neodiplostomumspathoides Dubois, 1937, Tylodelphysexcavata (Rudolphi, 1803), Pharyngostomumcordatum (Diesing, 1850), AstiotremamonticelliStossich (Diesing, 1851). For the first time, larvae of the cestodeSpirometraerinacei (Rudolphi, 1918) were found on this species of frog in the Volga basin. The helminth fauna of the moor frog is mostly composed of the nematodes Rhabdiasbufonis, Oswaldocruziafiliformis, Cosmocercaornata, and the trematodeHaplometracylindracea. The systematic location, localization, detection regions, kind of life cycle, geographic distribution, and level of host amphibian uniqueness of helminth species are all included.
