Allajulus nitidus (Verhoeff, 1891) .

This pale and comparatively large cylindroiulid (about 2 cm) was found in Charles University Botanical Gardens in 2000, and recently also on the northern fringe of Prague (Sedlecké skály - Prague 9), in 2002. Its habitat is dependent on the occurrence of limestone. Prague is the most eastern locality where it can be found. It is an Atlantic species, which occurs more frequently in western Europe. Taking into consideration the fact that this species is very particular in terms of climate and the basidity of soil, it is assumed that it colonises new territories with human assistance.
