description: <i>Natatolana prolixa</i> Bruce, 1986 <i>Natatolana prolixa</i> Bruce, 1986: 64, figs. 40, 41.– Brusca <i>et al</i>., 1995: 82.– Bruce <i>et al</i>., 2002: 152. <b>Type material</b>. Holotype: 3, 21.0 mm, QM W6738 (examined). Type locality: off Hay Point, Mackay, Queensland, Australia, 21°17'S 149°18'E. <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. 1.5× as long as body, reaching to beyond pleotelson. <i>Coxal plates</i>: furrows variously developed, indistinct furrows on coxae 2–3 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 0.75× basal width; anterodorsal depression absent; anterolateral margins convex; posterolateral margins concave; apex produced into a large point; RS absent. <i>Pereopod 2</i>: propodus with 2 RS on palm. <i>Pereopod 3</i>: propodus with 2 RS on palm. <i>Pereopod 7</i>: basis of medium breadth, width 0.5× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae along entire length. <i>Penes</i>: present (although the vas deferens are described as opening flush to the sternite surface by Bruce (1986), distinct penial processes are evident in the type material). <i>Pleopod 2 appendix masculina</i>: extending subequal with tip of endopod; slender; margins straight; apex not at angle to adjacent margins, acute. <i>Uropods</i>: exopod subequal to endopod, 0.95× the length of the endopod. <b>Sexual dimorphism</b>. Unknown. <b>Size</b>. Adults to 21 mm. <b>Remarks</b>. The long antennae and sinuate margins of the pleotelson that lack robust setae separate <i>Natatolana prolixa</i> from all other species in the genus. <b>Distribution</b>. Australia: Hay Point, Mackay, Queensland. At depths of 15– 21 m.
