Pleonobopyrus kumanonadensis gen. et sp. nov., a parasite of the crangonid shrimp, Prionocrangon dofleini Balss, 1913, is described on the basis of a female specimen collected from Mie Prefecture, off Owase, Pacific coast of central Japan. The specimen was attached to the ventral surface of the abdomen of the host shrimp. The species of the bopyrid subfamily Hemiarthrinae Markham, 1972, are known to occur on the abdomens of caridean shrimps, but morphological characteristics of the new species did not match those of Hemiarthrinae nor any other subfamilies. The attachment posture is backwards in contrast to that found in species of Hemiarthrinae. This new genus and species is the first abdominal bopyrid found on species of Prionocrangon.
