description: <i>Natatolana endota</i> Bruce, 1986 <i>Natatolana endota</i> Bruce, 1986: 63, figs. 38, 39.–Springthorpe &amp; Lowry, 1994: 44.– Brusca <i>et al</i>., 1995: 80.– Bruce <i>et al</i>., 2002: 150. <b>Type material</b>. Holotype: 3, 12.8 mm, AM P32172 (examined). Paratypes: AM P10693, P10689 (examined); TM G1505 (not examined). Type locality: off Sow and Pigs Shoal, Port Jackson, NSW, Australia, 33°20'S 151°16'E, 10 m. <b>Diagnosis</b>. <i>Interocular furrow</i>: moderately developed, distinct but not extending across the cephalon. <i>Frontal lamina</i>: lateral margins straight, parallel. <i>Antenna</i>: c. 1.3× as long as body, reaching to beyond pleotelson. <i>Coxal plates</i>: furrows variously developed, indistinct furrows on coxae 2–4 only. <i>Pleonite 2</i>: ventral posterolateral margin acute, formed into long curved process. <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 0.76× basal width; anterodorsal depression absent; anterolateral margins almost straight and angling posteriorly toward the midline; posterolateral margins straight, contiguous with anterolateral margins; apex narrowly rounded; with 4 RS. <i>Pereopods 1–6</i>: males with the RS on the merus of pereopods 1–3, and carpus of pereopods 4–6 shorter, than the propodus. Pereopod 2: propodus with 8 RS on palm. <i>Pereopod 3</i>: propodus with 8 RS on palm. <i>Pereopod 7</i>: basis of medium breadth, width 0.52× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae on proximal half. <i>Penes</i>: present (although Bruce (1986) describes the vas deferens as opening flush to the surface of the sternite). <i>Pleopod 2 appendix masculina</i>: extending subequal with tip of endopod, 1× length of endopod; slender; margins very slightly curved laterally; apex not at angle to adjacent margins, acute. <i>Uropods</i>: exopod subequal to endopod, 1× the length of the endopod. <b>Size</b>. Adults to 13.9 mm. <b>Remarks</b>. The antennular flagellum of <i>Natatolana endota</i> was described by Bruce (1986) as being longer than the peduncle but the illustration provided and examination of specimens indicates that it is shorter. <i>Natatolana endota</i> is readily distinguished from other species in having antennae that reach beyond the pleotelson and a pleotelson with straight lateral margins that converge to a narrowly rounded apex that has four robust setae. <b>Distribution</b>. Australia: Port Jackson, New South Wales; northern Tasmania At depths of 9– 23 m.
