A new species, Epithalassius gloagueni sp.n., is described and illustrated from the Trunvel-Tréogat Biological Nature Reserve (Brittany, France). This species can be distinguished from the similar E. sanctimarci from the Mediterranean Sea coast by the presence of only one long band-like outer lobe of the cercus. The male of E. sanctimarci has a cercus with two long band-like lobes of subequal size. An updated key to Palearctic species of Epithalassius is provided.
