Type locality. Russia, Volgograd Region, vicinities of Kotelnikovo settlement.

Type host. Arvicola terrestris .

Principal host. The European water vole, Arvicola terrestris ( Zemskaya, 1973) .

Distribution. Palaearctic (northern Eurasia). Widely distributed throughout Siberia, absent in the Russian Far East ( Nikulina, 2004).

Remarks. Costa (1961: 45) believed that Hy. amphibius and Hy. arvalis (= Hy. microti ) “are at the opposite ends of a series of intergrading forms of the same species”. Later on, Zuevsky (1968) presented additional morphological evidence favouring the separation of the two species.
