| Summary: | This is the second part of a revision of the most plesiomorphic genera in the amphipod family Stenothoidae sensu lato (see Krapp-Schickel and Koenemann 2006 for an overview and Krapp-Schickel 2008 for the first part). 41 species not belonging to Metopoides were plotted in a matrix using the same 61 characters as in the first part. The resulting group of Proboloides species (most probably not existing in the Austral-Antarctic region) is discussed, a key for the members given and two new genera erected. Some species described as Proboloides are redescribed and 2 species transferred to Metopoides . A key for all actual members of Proboloides and a revised key for Metopoides is added. The remaining species, i.e. those actually being in the genera Torometopa and Scaphodactylus , will be dealt with in the final part of this series, together with a key to all of them.
