title: Myostenostomum Bulbocaudatum (Catenulida, Stenostomidae): new for Ukraine, rare for the World.
abstract: At present, the stenostomid genus Myostenostomum Luther, 1960 according to Artois et al. (2013) contains 7 species: M. Bulbocaudatum Luther (type species), M. ilmenicum Rogozin, M. lutheri Rogozin, M. marcusi Rogozin, M. vanderlandi Rogozin, M. fasciatum (Veydovsky) and M. gigerium (Kepner & Carter), although the two latter are thought to belong to the genus Stenostomum Schmidt (Tyler et al. 2006-2015). A remarkable feature of the representatives of the genus Myostenostomum is a muscular ring on their gut.
