to 4, with the following numbers (n = 4): pereopod with 2 (43%) or 3 (50%), once (smallest manca); pereopod 2 with 2 (50%), (three times), or 3 and 4, each twice; pereopod 3 2 (64%) or 3 (three times) and 4 once; pereopod never had more than 3 robust setae on the propodal palm and no specimen had less than robust setae on any pereopod palm. The robust setae on the inferior margin of the merus were consistently +2. There was no difference between adults and mancas in the number of robust setae on the anterior pereopods. The rostrum is longer and straight in adult specimens whereas in mancas and small specimens it is bent slightly to the ventral. The single damaged ovigerous female had oo- stegites on sternites –5. The robust setae on the propodal palm of pereopods –3 are notably more slender and longer than those of immature specimens or non-ovigerous females; the number of robust setae on the palm of pereopods –3 is 3, as the most frequent number for the other specimens. remarks: Rocinela pakari sp. nov. can be identified by the wide propodal blade on pereopods –3 which is provided with – 4 robust setae in conjunction with well-separated eyes and a gently narrowed pleotelson posterior margin; in mature specimens the rostrum is relatively short, anteriorly rounded, and the lateral margins are very weakly stepped. Only four species of Rocinela have pereopods –3 with propodal blade as wide as the palm and provided with more than eight robust setae. Of those that do, three have eyes that meet in the middle (these being R. affinis, R. kapala and R. oculata) and all of these have fewer than 0 robust setae on the pereopod palm; the fourth species, Rocinela niponia Richardson, 909, a species in need of redescription, has separate eyes, fewer robust setae on the pereopod blade ( 0, 8 and 8 on pereopods to 3 respectively) and more robust setae (5) on the inferior margin of the merus. prey: Not known. distribution: Known only from the Chatham Rise, eastwards from the mid-coast of South Island. etymoLogy: Pakari is a Mäori word that means strong (noun in apposition).
