Three new species of the genus Pedicia, subgenus Crunobia (Diptera: Pediciidae) belonging to the staryi group are described on the basis of a combination of molecular and morphology datasets, and a key to discriminate between species of the subgenus Crunobia is added. Geographic projection of the identified taxa suggests insular-like distribution and shows the importance of the Carpathians as a genetic center which is home to an exceptionally high aquatic diversity in Europe.
Keywords: Crunobia; cryptic lineage; endemism; identification key; new species; re-description.
