Karaman Abstract.— The following new families are described or revived: Cardenioi-dae, Clarenciidae, Pseudamphilochidae, and Bolttsiidae (the latter two are com-panion families); the Ochlesidae are incorporated into the Acanthonotozo-matidae. The following new genera are described: Meraldia in Acanthonotozomatidae (Ochlesinae); Abdia, Manerogeneia, Membrilopus, Na-sageneia, and Whangarusa in Eusiridae; Geniculophotis in Isaeidae; Isipingus in Liljeborgiidae; Bruunosa, Cedwsella, Cicadosa, Galathella, Lepiduristes, and Rimakoroga in Lysianassidae; Stegosoladidus in Stegocephalidae; Aurometopa, Knysmetopa, Torometopa, Vonimetopa, and Zaikometopa in Stenothoidae; Hystriphlias in Temnophliantidae. The following change in nomenclature is proposed: Valettiella formerly in Lysianassidae is removed to Gammarella in the Nuuanuids (Pherusanids). We continue our series of expositions on new genera and nomenclatural changes nec-essary to realign various Amphipoda pre-paratory to our completion of a new com-pendium of genera in Gammaridea. Parts 1 and 2 are Karaman and Barnard (1979) and Barnard and Karaman (1982). As we have indicated before, the pro-mulgation of new taxa and substantive changes in others from the literature alone is not the most desirable of methods. We are trying to keep these changes to the min-imum, but in order to write keys to genera and otherwise to define genera as precisely as possible it becomes necessary to remove certain species from selected genera or cer-tain genera from selected families and to create new taxa. We base these changes on extensive review of the world literature in each taxonomic group. We recognize that many other taxonomists are engaged in re-visions of various taxonomic groups and have left them the task of realigning those. We frequently list species for each genus we change; for each species we list principal references and distribution in the style we propose to use in our forthcoming generic compendium. The distribution is cited as a three-digit number in brackets which can be determined from the list on pages 1 84-203 of Barnard and Barnard (1983). The method of description and citation of relationships follows the pattern of the aforementioned monograph. Any genus lacking reference can be found in J. L. Barnard (1969a). Acanthonotozomatidae (Ochlesinae), new combination, new rank Remarks.— New taxa recently described provide the intergradation necessitating amalgamation of Ochlesidae with Acan-thonotozomatidae. We retain Ochlesinae at subfamily level temporarily, although we have little conviction that any gross differ-ences are to be found. Ochlesinae are simply apomorphic acanthonotozomatids with loss of articles on the maxillipedal palp. One species of Ochlesis is so distinctive that it is relegated to a new genus, Meraldia. Diagnosis.— Body massive, compressed; anterior coxae acuminate or oddly shaped. Head short, tall, partially enveloped by pe-
