Type locality: Georgia, Kazbeghi District, vicinities of the villages of Kobi, Suatisi.

Type series: ZIN and the Department of Zoology of the North-Ossetian Pedagogical Institute (Vladikavkaz, Russia) .

Type host: Chionomys gud (Satunin, 1909), the Gudaur vole.

Host range: H. gudauricus infests hosts belonging to varied vole genera ( Alticola, Chionomys, Clethrionomys, Microtus); sometimes is collected from shrews (Razumova 1957; Senotrusova 1987; Mašán & Fend’a 2010). It seems that no species can be considered as the chief host of this generalist parasite.

Distribution: Northern and Central Europe, Caucasus, Kazakhstan, Western and Eastern Siberia (Senotrusova, 1987; Nikulina 2004; Huhta 2016); mostly in high mountain regions (Senotrusova 1987). Uchikawa (1974) recorded this species from Japan (as H. tatricus).
