Ecology and other information.

Ixodes pomerantzevi is a relict species occurring on the East Asian coast ( Filippova 1977) and in Russia its distribution is limited to a few locations in Outer Manchuria (a. k. a. Primorsky Krai) in the Russian Far East ( Tsapko 2020). It is also known to occur in Korea ( Kim et al. 2009 a, 2010, 2011) and China ( Guo et al. 2016). Predominantly it can be found in coniferous and broad-leaf forests, or secondary forests and bush thickets, as well as rock and stone outcrops among trees in the Sikhote-Alin and on the coast of the Sea of Japan ( Belyaev and Filippova 1976).

Luh and Woo (1950) supposed that I. pomerantzevi is possibly a synonym of Ixodes angustus ; Filippova (1977) considered it as valid and in the last list of valid tick species names, it is also considered valid ( Guglielmone et al. 2020).

Ixodes pomerantzevi is a nidicolous tick species, an ectoparasite of rodents, hedgehogs, and shrews ( Filippova 1977).

The type specimen of I. pomerantzevi is deposited at the Zoological Institute of the Russian Academy of Sciences and include the holotype: female; [ Russia], DVK [Primorskii Terr.], Suputinskii [Komarovskii or Ussurisky] Nature Reserve, from Myodes rufocanus , 9 – 13. VI. 1939, coll. B. I. Pomerantsev; AL I 502. Description – Filippova 1977: 128–132 (female, male - unknown, nymph, larva) ( Filippova 2008).
