description: <i>Bemlos aequimanus</i> (Schellenberg, 1938) (Figs 7, 8) <i>Bemlos aequimanus</i> (Schellenberg, 1938). <i>Lembos aequimanus</i> Schellenberg, 1938 b: 76, fig. 39. —J.L. Barnard, 1965: 527, fig. 26. —J.L. Barnard, 1970: 72, fig. 36a–e. — Ledoyer, 1984: 31, fig. 14. — Myers, 1985b: 385, figs 246–248. <i>Bemlos aequimanus</i>. — Myers, 1988a: 188. — Myers, 1988b: 282. — Lowry &amp; Stoddart, 2003: 67 (catalogue). <b>Material examined</b>. 1 male, AM P77556 (JDT/LIZ 14); 1 unsexed, AM P75587 (QLD 1897); 1 unsexed, AM P75588 (QLD 1914); 2 unsexed, AM P75586 (QLD 1979). <b>Type locality</b>. Apamama Atoll, Kiribati (as Gilbert Islands) (~ 0°24'0''N 173°52'0''E). <b>Description.</b> Based on male, 7.0 mm, AM P77556. <b>Head.</b> <i>Head</i> lateral cephalic lobes apically truncate. <i>Antenna 1</i> flagellum with 21 or more articles; accessory flagellum multiarticulate. <i>Antenna 2</i> with few long setae. <i>Lower lip</i> with fine setae only. <i>Maxilla 1</i> inner plate with 1 long pectinate apical seta. Mandible palp article 3 longer than 2, posterior margin straight with setae of two distinct lengths, long setae and an under-story of much shorter regularly spaced setae. <b>Pereon.</b> <i>Pereonites 2–3</i> with weak, apically rounded sternal spines. <i>Gnathopod 1</i> enlarged in males only; coxa anterodistally rounded; basis slender, much less than half as broad as long, with few or no setae present along margin, anterodistal margin with flange weak or absent; ischium anterior margin without flange; merus not greatly elongated, fused along its entire length with carpus, posterior margin with sparse setae or setae absent, without posterodistal spine; carpus one third or less length of propodus, with setae sparse or absent, carpus without spines; propodus anterior margin moderately clothed in short setae, palm delimited from posterior margin, margin forming a broad excavate sinus, defined by strong posterodistal spine; dactylus more than half length of propodus, significantly overlapping palm. <i>Gnathopod 2</i> subchelate; basis anterior margin basis anterodistal margin with weak flange, weakly setiferous; carpus subequal with propodus, with short sparse setae; propodus with short dense setae. <i>Pereopod 3</i> basis anterior margin unexpanded, straight or weakly concave. <i>Pereopod 7</i> significantly less than 125% length of pereopod 6. <b>Pleon.</b> <i>Epimeron 3</i> posterodistal margin produced into a small spine. <i>Uropod 1</i> distoventral spine one third length of peduncle. <i>Uropod 2</i> peduncle with distoventral spine one half length of peduncle. <i>Uropod 3</i> biramous, outer ramus a little shorter than inner ramus, inner ramus at least twice length of peduncle. Telson with fine setae only. <b>Female</b> (sexually dimorphic characters). Not collected in the current survey. <b>Habitat.</b> Among algae and phanerogammes in shallow water. <b>Remarks.</b> The large size of this species is exceptional for this genus. Worldwide, only the closely related <i>B. teleporus</i> K.H. Barnard, 1955 from the western Indian Ocean is comparable in size. Together with size, the shape of the male gnathopod 1 distinguishes this species from all other Great Barrier Reef species of <i>Bemlos</i>. <b>Distribution.</b> <i>Australia</i>. Queensland: south of Lizard Head Peninsula, Lizard Island (current study); Dingo Beach near Bowen Island (Myers 1988b). New South Wales: Twofold Bay (Myers 1988b; Hutchings, <i>et al.</i> 1989). Victoria: Crib Point (Myers 1988b). South Australia: Stokes Bay, Kangaroo Island (Myers 1988b). <i>Fiji</i>. Viti Levu (Schellenberg 1938; Myers 1985). <i>Kiribati</i>. Apamama Atoll (Schellenberg 1938). <i>New Caledonia</i>. l'îlot Maître (Ledoyer 1984). <i>USA</i>. Hawaii: Kawela Bay, Oahu (J.L. Barnard 1970).
