Pereopod 2 merus inferior margin with 5 RS (set as 3 and 2), set as two groups, superior distal margin with 2 acute RS; carpus inferodistal angle with RS (minute). Pereopod 3 similar to pereopod 2. Pereopods 5–7 inferior margins <strong>of</strong> ischium–carpus 82 with long acute RS. Pereopod 7 basis 3.5 times as long as greatest width, inferior margins with 6–8 palmate setae; ischium 0.5 as long as basis, inferior margin with 6 RS (set as , 3, and ), superior distal angle with 5 RS, inferior distal angle with 6 RS; merus 0.7 as long
as ischium, .8 times as long as wide, inferior margin with 5 RS (set as 2 and 3), superior distal angle with 6 RS, inferior distal angle with 6 RS; carpus 0.9 as long as ischium, 3.3 times as long as wide, inferior margin with 2 RS (single cluster), superior distal angle with 4 RS, inferior distal angle with 7 RS; propodus 0.7 as long as ischium, 4.2 times as long as wide, inferior margin with 2 RS, superior distal angle with 2 slender setae (palmate), inferior distal angle with 2 RS. Penes opening flush with surface <strong>of</strong> sternite 7; penial openings separated by 3.3% <strong>of</strong> sternal width. Uropod peduncle ventrolateral margin with RS (and 3 short setae), posterior lobe about two-thirds as long as endopod. Uropod rami apices narrowly rounded. Endopod apically not bifid, lateral margin proximally convex (weakly), with prominent excision, positioned about two-thirds along ramus, proximal lateral margin with 4 RS, distal lateral margin with 5 RS, mesial margin weakly convex, with 5 RS. Exopod not extending to end <strong>of</strong> endopod, 2.8 times as long as greatest width; lateral margin weakly convex, with 8 RS; mesial margin sinuate, proximally concave, with 4 RS. remarks: <strong>The</strong> characteristic setation <strong>of</strong> the anterior pereopods, which has the distal robust setae on the merus notably longer than the preceding robust seta, allows ready identification; the sub-rectangular frontal lamina, lack <strong>of</strong> a lobe on the propodal palm <strong>of</strong> pereopods –3, the uropodal exopod not extending beyond the endopod and number <strong>of</strong> robust setae on the uropods are further characters by which the species can be identified. prey: Previously recorded from bony fish, sharks and rays (Bruce 2004a); here recorded from the Galapagos shark, Carcharhinus galapagensis (Snodgrass & Heller, 905) (Carcharhinidae). distribution: From eastern Australia at Moreton Bay and the Solitary Islands to Elizabeth Reef, Norfolk Island and the Kermadec Islands; here recorded from Lord Howe Rise; depth range is relatively shallow, from a few metres to 75 metres, considerably shallower than most related species. Genus Aegiochus Bovallius, 885 Aegiochus Bovallius, 885: 4. Aega (Ramphion) Brusca, 983: .– Kensley & Schotte, 989: 6 (key) [type species Aega plebeia Hansen, 897; by original designation]. type speCies: Type species is Aega nordenskjoldii Bovallius, 885, by monotypy; junior synonym <strong>of</strong> A. ventrosa M. Sars, 859. Four specimens <strong>of</strong> A. ventrosa (ZMUC) were examined. 83 diagnosis: Body moderately to strongly dorsally vaulted. Rostral point separating antennule peduncles, appearing truncate in dorsal view, ventrally or ventrally and posteriorly directed. Eyes present, <strong>of</strong>ten large, sometimes medially united. Pleonite not abruptly narrower than pereonite 7; pleonite 4 with lateral margins extending to or beyond posterior margin <strong>of</strong> pleonite 5. Antennule peduncle articles and 2 cylindrical, not flattened or expanded. Maxillule with –3 large broad-based RS, several small RS. Maxilliped palp article 5 longer that wide, subtruncate, with long setae; endite present. Pereopods –3 merus inferior margin with small RS, usually set as two groups. desCription: Body moderately to strongly vaulted, about 2 to 4 times as long as wide. Head with eyes, <strong>of</strong>ten large, may meet at midpoint; anterior margin with median (rostral) point. Coxae 4–7 longer than respective segment, posteriorly produced. Pleon not abruptly narrower than pereon; pleonites all visible, not posteriorly widest, pleonite 5 laterally overlapped by pleonite 4. Frontal lamina present, with free posterior margin or with posterior stem. Mandible with uni- or bicuspid incisor; molar process present, reduced or absent. Maxillule with single large, flat, broad-based RS, several small RS. Maxilliped palp 5-articled, article shorter than wide, articles 3 and 4 each with 2–6 stout recurved RS; endite present, usually with –2 terminal setae. Uropod rami with endopod and exopod co-planar, rami extending to or slightly beyond pleotelson apex, marginal setae in single tier, apices acute. remarks: <strong>The</strong> genus Aegiochus was established by Bovallius ( 885) on the basis <strong>of</strong> a biological misinterpretation. <strong>The</strong> holotype <strong>of</strong> Aegiochus nordenskjoldii was an intermoult specimen, this fact being quickly recognised by subsequent workers (e.g. Hansen 890; Sars 899) who placed the genus into synonymy with Aega. <strong>The</strong> species was also quickly recognised to be a junior synonym <strong>of</strong> Aegiochus ventrosa (as Aega ventrosa). Brusca ( 983) recognised that there were two large ‘groups’ within Aega, and established the subgenera Rhamphion and the nominate subgenus. Brusca’s subgeneric assignments were based on direct examination <strong>of</strong> 23 species and literature for a further 30 species (<strong>of</strong> a then total <strong>of</strong> about 60 species), with the primary basis for distinguishing the two subgenera being the presence (or absence) <strong>of</strong> expanded peduncular articles on the antennule, presence or absence <strong>of</strong> a distinct rostrum, and presence or absence <strong>of</strong> recurved ‘spines’ (robust setae) on the ‘apex <strong>of</strong> the maxilliped palp’. Some workers initially followed the use <strong>of</strong> the subgenera (e.g. Bruce 983; Wetzer 990; Kensley & Schotte 989) but later found that critical characters were inconsistently present within
