Ecology and other information.

Ixodes stromi is a tick species only indigenous to southern Siberia in Russia ( Tsapko 2020). The main part of its distribution spans in Kazakhstan and Middle Asia. In all territories of its range, it is confined to the forest-meadow and forest-steppe belt of medium-altitude mountains, to stony and rocky habitats, which are insolated and, therefore, have a warmer microclimate ( Filippova 1967).

This species is nidicolous and uses rodents, shrews, and small carnivores as hosts at all stages. It is considered a rare species reaching small individual number ( Filippova 1977).

The type specimens of I. stromi are known from Kyrgyzstan and stored at the Zoological Institute of the Russian Academy of Sciences: the lectotype: the nymph; Kyrgyzstan, Tien Shan, Kungei Ala Tau Mt. Range, Ch-Aksu Canyon, talus, from Clethrionomys frater (synonym of Myodes centralis ), 11. VIII. 1953, coll. N. А. Filippova; AL I 78. The paralectotypes: 6 larvae; FBM I 586, I 876; 6 larvae; FBM I 873, I 875. Description – Filippova 1977: 122–127 (female, nymph, larva; male unknown) ( Filippova 2008).
