which extend beyond the pleotelson, the exopod of which is shorter than the endopod and is proximally narrow. Comparison with the holotype of S. intermedius (see Appendix 2) shows that, in S. intermedius, the frontal lamina is narrower, the posterior legs are more robust, the uropod rami are roughly subequal in length, the coxae are posteriorly rounded and the pleotelson lateral margin has a distinct inflexion. Syscenus kapoo is also similar to the potentially sympatric S. moana, from which it differs in having a far shorter antennal flagellum (to pereonite 3 v. pereonite 6 in S. moana), the robust setae on the merus and carpus of pereopod 7 are larger, and the uropods differ in lacking robust setae, the endopod being more slender, and the exopod is shorter than that of S. moana, and different in shape being wider distally as well as narrower proximally. prey: Not known. etymoLogy: The epithet is a Mäori word meaning blind or without sight. distribution: Known only from the type locality, on the Norfolk Ridge.
