The poorly known species Oedicerina ingolfi Stephensen, 1931 (Crustacea: Amphipoda: Oedicerotidae) is redescribed, based on new material from the Norwegian Sea. Oedicerina vaderi sp. n. from the northeast Atlantic Ocean and Oedicerina loerzae sp. n. from New Zealand waters are described raising the number of species in the genus to five. The three species treated here together with Oedicerina megalopoda Ledoyer, 1986 and Oedicerina denticulata Hendrycks & Conlan, 2003 are separated by characters of the rostrum, maxilliped, gnathopods, epimera, and by the dorsal armature of pleonites and urosomites. The genus is recorded from the Atlantic, Indian and Pacific Oceans, mainly at bathyal depths.
