Materials to the helminth fauna of the pool frog Pelophylax lessonae (Camerano, 1882) in Togliatti (Samara region)

The results of a research of helminthes fauna of a pool frog Pelophylax lessonae (Camerano, 1882) in reservoirs of Togliatti (Samara region) and the vicinities are presented. In 2005, 2009-2011 and 2014 years the method of the full helminthological autopsy studied 95 amphibians from four localities. Found 24 species of helminthes: Trematoda (20) and Nematoda (4). For the first time for this host 4 species of helminthes are specified: Codonocephalus urnigerus (Rudolphi, 1819), mtc., Neodiplostomum spathoides Dubois, 1937, mtc., Pharyngostomum cordatum (Diesing, 1850), mtc. and Icosiella neglecta (Diesing, 1851). Composition of helminthes is typical for a midland of Russia and varies in different populations of the host. In structure adultes stages (marita) of trematodes dominate; the minority is presented by geonematodes; the quantity of species of larval stages of helminths (trematodes) increases in process of removal from the city.
