description: <i>Limnoporeia cooki</i> sp. nov. (Figs 13, 14, Pl. 5G) <b>Type material.</b> Holotype female 2.0 mm, AM P 71013, 500 m north-east of North Point, Lizard Island (14°38.700’S 145°27.213’E), 23.9 m, R. T. Springthorpe, 27 February 2005 (QLD 1707). Paratype: female 2.0 mm, AM P70632 (QLD 1621). <b>Type locality.</b> North-east of North Point, Lizard Island, Queensland, Australia. <b>Additional material examined.</b> 1 female (damaged), AM P71452 (QLD 1836). <b>Etymology.</b> Named for English navigator James Cook who, in 1770, climbed to Lizard Island's summit in a desperate bid to find a way out of the labyrinth of reefs within which he found himself trapped. <b>Description.</b> Based on holotype female. <b>Head.</b> <i>Rostrum</i> unconstricted; eyes present. <i>Antenna 1</i> peduncle article 2 with ventral setae confined apically, article 2 produced mediodistally beyond midpoint of article 3. <i>Antenna 2</i> peduncle article 4 facial robust setae in 1 main/apical row, dorsal setae absent or with 1 short setule; article 5 midfacial robust setae present as a single set of 1–3. <i>Maxilla 1</i> inner plate unknown; outer plate without an especially thickened robust seta; palp uniarticulate. <i>Maxilliped</i> inner plate without large thick apical robust setae; outer plate inner margin poorly armed, with 6 or fewer setae. <b>Pereon.</b> <i>Coxae</i>, long posteroventral setae present on coxae 1–3, absent from coxa 4, main ventral setae of coxae 1–4 = 4–5–5–0. <i>Coxa 1</i> expanded distally. <i>Gnathopods</i> chelate, slightly dissimilar. Gnathopod 1 carpus free (not cryptic), gnathopod 2 carpus cryptic. <i>Pereopods 3–4,</i> carpus lacking posteroproximal robust setae, propodus slender setae absent. <i>Pereopod 5</i> basis of broad form, tapering distally (slightly), with 1 facial ridge. <i>Pereopod 6</i> basis with 1 facial ridge. <i>Pereopod 7</i> basis with few or no long ventral setae, without facial ridge. <b>Pleon.</b> <i>Epimeron 1</i> anteroventral margin without setae, posteroventral face without setae. <i>Epimeron 2</i> without facial setae. <i>Epimeron 3</i> facial setae absent, with 1 short posterior setae, without facial setae, without ventral setae or with very short setules only. <i>Uropods 1–2</i> rami naked, without apical nails. <i>Uropod 1</i>, peduncle with 1 basofacial setae, without major displaced robust setae, with 1 apicolateral spine; inner ramus with 1 dorsal spine, without subapical accessory robust setae; outer ramus not continuously spinose to apex. <b>Habitat.</b> <i>Halimeda</i> sp. (green alga) with epiphytes, soft bottom with foraminifera, crinoids, <i>Halimeda macroloba, Halimeda cylindracea, Caulerpa taxifolia, Gracilaria</i> sp., <i>Lobophora</i> sp. and sediment. <b>Remarks.</b> The carpus of gnathopod 1 is shortened in comparison with most other species (<i>L. maranowe</i>, <i>L. woorake</i>, <i>L. ungamale</i>, <i>L. wakkine</i> and <i>L. kalduke</i>). The unreduced and non-recurved dactyl of pereopod 3, and lack of apicoventral process on rostrum distinguishes this new species from other known species of the genus. See also remarks for <i>L. woorake</i> herein. <b>Distribution.</b> <i>Australia.</i> Queensland: Lizard Island (current study).
