Two new species of the millipede family Blaniulidae (Diplopoda, Julida) from caves in central and southeastern Europe.

Two new species, one each of the previously monotypic genera Cibiniulus Verhoeff, 1927, and Thassoblaniulus Mauriès, 1985, are described from caves in Slovakia and Albania, respectively: C. slovacus Antić, Mock & Enghoff, sp. n. and T. radjai Antić & Enghoff sp. n. Brief discussions on relationships with congeners and on the taxonomic position of the genera Cibiniulus and Thassoblaniulus within Blaniulidae are presented, as well as a distribution map for both genera.
