Type locality: No exact type locality is reported. Bregetova (1956) cited findings of this species from Estonia, some regions of European Russia, as well as from western Kazakhstan.
Type series: Unknown (not found in ZIN) .
Type hosts: Sorex araneus Linnaeus, 1758 and Neomys fodiens Pennant, 1771 .
Host range: Though H. eusoricis is usually regarded as a specific parasite of shrews and other soricimorph mammals (Zemskaya 1973; Senotrusova 1987), the findings of this mite from different species of rodents and even from bird nests are known (Nikulina 2004; Mašán & Fend’a 2010). Anyway, the insectivores remain the principal hosts for this parasite.
Distribution: Northern Eurasia; widespread in Asiatic Russia, where occurs in both Siberia and the Russian Far East (Davydova & Nikol’sky 1986; Nikulina 1987, 2004; Goncharova et al. 1991).
Notes: Tenorio (1984) supposed that H. eusoricis may be a synonym of H. soricis (Turk, 1945) . This synonymy has been accepted by Mašán & Fend’a (2010) but not followed by Russian authors (Nikulina 1987, 2004; Goncharova et al. 1991; Korallo 2009).
