Taxonomic notes: 1 This is a group of very similar and highly variable species: Ecrobia ventrosa, Hydrobia acuta and Eupaludestrina stagnorum not easily distinguishable by the shell features; 2 Bela formica is considered taxon inquirendum previously synonymized with Bela nebula; 3 commonly reported as Tritia pygmaea (Lamarck) a junior secondary homonym of Muricites pygmaeus Schlotheim.
