The interstitial harpacticoid genus Psamathea Cottarelli & Venanzetti, 1989 (Leptastacidae) is revised. The type species P. nautarum is redescribed on the basis of new material collected from the shallow subtidal off Banyuls-sur-Mer. Notopontia (?) sp. sensu Bodin (1984) from the Bay of Douarnenez in Brittany is described as the second species in the genus: P brittanica sp. n. The problematic phylogenetic position of Psamathea in the Leptastacidae is re-assessed in the light of the new information available. The resemblance in caudal ramus structure and swimming leg sexual dimorphism favours a sistergroup relationship with Paraleptastacus C.B. Wilson.
