Cylindroiulus parisiorum (Broelemann & Verhoeff, 1896) .

This is a European, synanthropic species, which also occurs in tree hollows and rotted wood. Its widespread distribution in Europe indicates no special demands in terms of habitat. The direction of spread in Europe is not obvious. The origin is considered to be the Atlantic geographic zone. This species was found in 1988 in Prague 7, Cisar˘sky’ island. It might have been inhabiting our territory for some time before being discovered, because it is very inconspicuous. When colonising new habitats, this species moves along river banks.
