Ecology and other information.
Ixodes kaiseri is a typical nidicolous parasite of carnivores and also hedgehogs and porcupines which is morphologically very similar to I. crenulatus and has common sympatric zones with this species along its range (Filippova 1999). Its range itself is patchy and disjunctive areas of sympatry for both of these species are found in southeastern Europe - Romania, Moldova, Ukraine, including the Crimean Peninsula as well as in Russia - the southwestern extremities of the Central Russian Upland and the Northern Caucasus; then after a long gap - in Western Kazakhstan and again after a big gap - in the Dzungarian Alatau (Filippova 1999). Judging by literature, it is also known from Egypt and Israel (Arthur 1957, 1960, 1965). As Filippova and Uspenskaya (1973) assumed, its distribution in the Middle East and also other parts of Asia can be wider than it is known at present, which was already confirmed by the findings of this tick species in Turkey (Orkun and Karaer 2018) and Xinjiang in China (Zhao et al. 2019) near the border with Kazakhstan and the Dzungarian Alatau and hence, it is possible that the sympatry of these two species is more widespread. This is also supported by literature data, because until the 1970 s in the territory of the former USSR I. kaiseri was not differentiated from I. hexagonus and I. crenulatus (Emelyanova 1979; Filippova 1999).
These species not only inhabit the same territory and inhabit the same biotopes in some places but can also parasitize one host individual at the same time (Tsapko 2017). It is also important to note that according to Filippova’s opinion (1999), the territorial signs of the ranges of these two species, their biotope and host-parasite relationships indicate that the range of I. crenulatus (which is predominantly connected with marmots and their burrows in steppe and forest-steppe zones) over the most part of its distribution has a Central Asian origin, while the range of I. kaiseri (mainly the parasite of carnivores and occurring in their burrows) is supposedly of European origin.
