Laelaps grubei Oudemans, 1938: LXXI.
Laelaps lemni (sic).— Oudemans, 1927: 195.
Type locality. Northern Siberia.
Type host. Lemmus obensis (Brants, 1827) = Lemmus sibiricus (Kerr, 1792).
Principal hosts. Lemmings of the genus Lemmus Link, 1795 (according to Zemskaya, 1973).
Distribution. Northern Eurasia, from Scandinavia to Chukchi Peninsula (Edler & Mehl, 1972; Zemskaya, 1973; Bogdanov, 1975; Nikulina, 2004). The species’ range coincides with the range of its principal hosts, Lemmus sibiricus and L. lemmus (L., 1758). In Asiatic Russia, the species inhabits the northern parts of Siberia and the Russian Far East; recorded also from Transbaikalia (Nikulina, 2004). Although Lemmus is known from the Dutch fossil record (Dieleman, 2013), a finding of this mite species from the Netherlands reported by Oudemans (1896) seems to be the result of misidentification.
