03EE87FD46261F2CFF55075B4D617211.taxon	discussion	Remarks. According to Rothschild and Traub (1983), we consider Amalaraeus penicilliger as a Palaearctic subspecies group. Our finding of Am. penicilliger in Belarus is the first geographical record. Arboreal behaviour is an extremely important feature of the spatial activity of small muroid rodents (superfamily Muroidea) (Stepankova, Vohralik 2009). Vertical activity has also been observed in voles and shrews (Bobretsov et al. 2019). Nyctalus noctula is a tree-dwelling species that prefers hollows of large deciduous trees, and Myotis daubentonii is also able to inhabit tree hollows. This probably explains why fleas common to other orders of mammals are found on bats. To understand the role of bats in spreading dangerous focal infections, further research is necessary.	en	Orlova, Maria V., Larchanka, Aleksandra I., Dolgova, Irina G., Dziamianchyk, Viktar V.
