Figure 125. Rocinela runga sp. nov. Holotype. A–C, pereopods , 2 and 7 respectively; D, pereopod , merus, distal inferior margin; E, pereopod , propodus, distal inferior margin, F, pereopod 2 ischium, mesial angle; G, pereopod 7, distal margin of carpus, mesial RS; H, uropod; I, uropodal exopod, ventral view. Variation: The uropodal endopod mesial margin had 4 and 6 robust setae, lateral margin 4 and 5 robust setae. remarks: Rocinela runga sp. nov. can be identified by the ovate body shape, relatively small and widely separated eyes, smoothly narrowed rostrum, very long (longer than pereopod 7) and slender pereopod 92 , pereopods –3 without a propodal blade and by the relatively narrow uropodal rami. Rocinela leptopus sp. nov. is the only other similar species, with a similar pereopodal, pleotelson and uropod morphology. The two species are readily separated by R. runga having a more elongate pereopod , pereopod dactylus distally curved (proximally curved in R. leptopus), more slender pereopods 2 and
3, and uropodal rami that are relatively wider (exopod 3.4 times as long as wide) than in R. leptopus (exopod 4.0 times as long as wide) and which fail to exceed the posterior margin of the pleotelson (just exceeding the posterior margin of the pleotelson in R. leptopus. prey: Not known. distribution: Known only from off the Antipodes Islands, eastern Campbell Plateau, southeast of New Zealand. etymoLogy: Runga is a Mäori word meaning south (location) alluding to the southern location (noun in apposition).
