description: <i>Natatolana narica</i> (Bowman, 1971) <i>Cirolana narica</i> Bowman, 1971: 107, figs. 1–22. <i>Natatolana narica</i>.– Bruce, 1981: 958.– 1986: 64, 222.– Brusca <i>et al</i>., 1995: 82. <b>Type material</b>. Holotype: 3, 21.8 mm, ZMUA Is. 100.527. Paratypes: 3, 21.9 mm, USNM 139048;? ♀, 17.3 mm, ZMUA Is. 100.528. None examined. Type locality: Banks Peninsula, South Island, New Zealand [43°50'S 173°E], from vestibular diverticulum of <i>Cephalorhynchus hectori</i>. <b>Material examined</b>. <b>New Zealand</b>: 3, 3♀♀, QM W18895, [Tasman Bay], 41.18°S, 173.16°E, 0 m, isopod trap, ex New Zealand Oceanographic Institute, K 225A; 3, ♀, NMNZ Cr 4434, Otago Harbour, 20.3 m, 23 Feb. 1962, loc. 10520. <b>Diagnosis</b>. <i>Eyes</i>: vestigial (ommatidia are indistinct and lack pigment). <i>Interocular furrow</i>: well developed, forming a ridge that extends across the cephalon; smoothly convex. <i>Frontal lamina</i>: lateral margins medially constricted. <i>Antenna</i>: c. 0.3–0.4× as long as body, reaching to threequarters of the way along pereonite 4. <i>Coxal plates</i>: furrows variously developed, incomplete and indistinct on coxae 2–4, 7. <i>Pleonite 4</i>: posterodorsal margin strongly concave proximal to meeting posteroventral margin at apex; apex forming a narrow acute point. <i>Pleotelson</i>: broad, length 0.75× basal width; anterodorsal depression absent; anterolateral margins almost straight and angling posteriorly toward the midline, or convex; posterolateral margins broadly rounded; apex not produced, truncate with a small medial point; with 8–12 RS (material examined 8–10, types described as having about 12). <i>Pereopod 2</i>: propodus with 0–1 RS on palm. <i>Pereopod 3</i>: propodus without RS on palm. <i>Pereopod 7</i>: basis broad, width 0.56× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae on proximal third. <i>Penes</i>: absent. <i>Pleopod 2 appendix masculina</i>: extending beyond tip of endopod, 1.06× length of endopod; margins straight or very slightly curved laterally; slender; apex not at angle to adjacent margins, bluntly rounded. <i>Uropods</i>: exopod longer than endopod, 1.15× the length of the endopod. <b>Size</b>. Adults to c. 21 mm. <b>Remarks</b>. <i>Natatolana narica</i> and <i>N. paranarica</i> n.sp. are the only species of <i>Natatolana</i> in which the uropod exopod is distinctly longer than the endopod. <i>Natatolana paranarica</i> is almost identical to <i>N. narica</i> but differs in that the posterolateral margins of the pleotelson meet at an acute angle, rather than being broadly rounded; the uropod endopod medial margin is smoothly convex, not sinuate; the ventral margin of the posterior coxae is straight not sinuate; there are slender setae at the uropod endopod and exopod apices that are shorter than the length of these rami, rather than being as long as them. <b>Distribution and ecology</b>. New Zealand. Intertidal to 20.3m depth. <i>Natatolana narica</i> has been collected from nasal tract of a dolphin, it is unlikely to be a parasite as entry probably occurred while the dolphin was dead or dying (Bowman, 1971) and the species is likely to be a scavenger.
