In Greece, scorpion genus Euscorpius has been insufficiently studied. Taxonomy of several species and subspecies has been inconsistent and confusing. We provide new morphological data and redescriptions of type specimens of three “old” taxa, described from Greece and formerly listed under a “catch-all” taxon Euscorpius carpathicus. We elevate to, or confirm at species status: Euscorpius scaber Birula, 1900 (type locality: Mt. Athos), E. candiota Birula, 1903 (type locality: Heraklion, Crete), and E. ossae Di Caporiacco, 1950, stat.n. (type locality: Mt. Ossa, Thessaly). Species-level separation of these taxa is also confirmed by multiple species delimitation methods implemented on the phylogenetic data generated using four different DNA markers.
