Metabelba (Pateribelba) flagelliseta Bulanova-Zachvatkina, 1965 is redescribed based on the newly sampled material from Crimea and investigation of the specimens from the collection of Bulanova-Zachvatkina. Metabelba (Metabelba) pseudoflagelliseta Kolesnikov & Murvanidze sp. nov. is described from Caucasus, Georgia. Both species have similar morphology, characterized by flagellated notogastral setae and same set of tubercles, but differ by presence or absence of apophysis P and shape of the dorsal seta on femora III–IV. Considering the importance of these morphological characters we assign these species to different subgenera.
