Abstract

We establish a new pseudozeuxid genusHaimormusgen. nov. based on a new speciesHaimormus shimojiensissp. nov. which was collected from a submarine limestone cave with the entrance at 35 m depth, in the Northwestern Pacific Ocean.H. shimojiensisdiffers from the other confamilial members,Pseudozeuxo belizensisSieg, 1982 andCharbeitanais spongicolaBamber & Bird, 1997, in having the pleonite 1 without the pleopod, the pereopods 2 and 3 propodus with a ventral spiniform seta, and the pereopods 4–6 propodus with one long and two short dorsodistal setae. A key to females of species of Pseudozeuxidae is presented. This is the first tanaidacean report from submarine caves around Japan.
