Status Ischyrocerus kapu J.L. Barnard, 1970 from Hawaii. The author based the generic assignment on a single male specimen. He noted its resemblance to N. lilipuna but also considered that it should be in a new genus. On balance, though, he assigned it to Ischyrocerus but noted that this was based on limited information because the specimen lacked antennae and pereopods and the female was also unknown. The male’s gnathopod 2 is unusual in having a long conical extension of the merus underneath the propodus, a feature that is not known for either Ischyrocerus or Neoischyrocerus. Myers (1995) stated that I. kapu is congeneric with other species being transferred to Neoischyrocerus. The male’s propodus is wider than in other members of Neoischyrocerus, but its uropod 3 resembles other species of Neoischyrocerus rather than Ischyrocerus. Further material demonstrating the species’ complete morphology is required before it can be confidently transferred to Neoischyrocerus or to a new genus. [details]
