A New Blind Mysid Genus, Eoamblyops, from Japan with the Description of a New Species (Crustacea, Mysida, Mysidae, Erythropinae)

A new blind mysid genus, Eoamblyops, is established. It is distinguished from allied genera by having the eyes reduced to two semicircular plates, the antennal scale with a denticle located at the distal end of the lateral margin and unarmed with any subsidiary spinule in its inner side, the antennal peduncle composed of three segments ranged straight, the antennal sympod with two denticles at the distolateral corner, the labrum pointed anteriorly, third to eighth thoracopods with very slender endopods, and the second to fifth male pleopods with side lobes slender and not dilated distally. A new species belonging to this new genus, E. japonicus, is described.
