Saint-Pierre and Miquelon is a French self-governing overseas territory near the Canadian province of Newfoundland and Labrador. Seven diadromous species occur in the rivers and ponds of this archipelago: Anguilla rostrata (Lesueur, 1817), Osmerus mordax (Mitchill, 1814), Salmo salar Linnaeus, 1758, Salvelinus fontinalis (Mitchill, 1814), Apeltes quadracus (Mitchill, 1815), Gasterosteus aculeatus Linnaeus, 1758 and Pungitius pungitius (Linnaeus, 1758). For each species, we review nomenclature, give all arguments delineating the taxon according to an integrative approach (morphology, molecular, time divergence, cytogenetics, life traits histories, ecology, ethology, reproductive isolation), as well as their distribution in the archipelago and their IUCN status. We highlight taxonomical issues among O. mordax, S. salar and P. pungitius for which a taxonomical revision is needed. We consider the genus nomen Anguilla Thunberg, 1795 as not available according to the International Code of Zoological Nomenclature. ...
