MYSIDACEA FROM THE CENTRAL AND WESTERN PACIFIC II. -GENERA HYPERAMBLYOPS, TERATERYTHROPS AND SYNERYTHROPS (TRIBE ERYTHROPINI)-

Abstract

In the present paper the genera Hyperamblyops, Teraterythrops and synerythrops are discussed. Many of the species belonging to these three genera seem to be in confusion with respect to their taxonomy. Fortunately, many specimens of these species were caught in the collections, so I attempted to give the definition of these genera and to clear away the confusion. Moreover, the description on a new species of Synerythrops, S. truncata, and the details of the geographical and vertical distribution of Teraterythrops robusta are also reported. I should like to express my thanks to Dr. Naoyoshi Ii for his helpful criticism and valuable advice. Thanks are also due to Professor Ryuzo Marumo, Ocean Research Institute, University of Tokyo, for the opportunity of examining the specimens stored in his Institute.
