Psammocyclopina georgei sp. n. is described from submersed sands in the Magellan Strait, South Atlantic Ocean. This is the second species of the genus, previously known only from the Indian Ocean (Mozambique). Psammocyclopina Wells, 1967 is the sistergroup of Metacyclopina Lindberg, 1953. Psammocyclopinidae fam. n. is accordingly proposed to unify these genera into one monophyletic unit. The sistergroup of the new family is a cluster of cyclopinid genera composed of Cyclopinodes Wilson, 1932, Pseudocyclopina Lang, 1946, Parapseudocyclopinodes Lindberg, 1961, Hemicyclopina Herbst, 1952, Procyclopina Herbst, 1955, Heterocydopina Plesa, 1968, Neocyclopina Herbst, 1952, and an as yet undescribed new genus (Martinez Arbizu, in prep.). Global occurrence of psammocyclopinids is briefly reviewed.
