Two species of Roncus L. Koch, 1873 (Neobisiidae), new to science (R. ciobanmos n. sp. and R. dragobete n. sp.), and one species of Neobisium Chamberlin, 1930 [N. (N). biharicum Beier, 1939], collected in the Movile Cave, southern Dobrogea, Romania, have been described, diagnostic characters illustrated, and their geographic distribution analyzed. In addition, the description of Chthonius (Chthonius) monicae Boghean, 1989 (Chthoniidae), otherwise known only from two females, has been amended. The possible relationships of these species are discussed in view of the importance of some diagnostic characters and of the evolution of their cave habitat.
