Aega (Aega) angustata.– Brusca, 983: 0. Not Aega angustata.– Stephenson, 980: 53, figs –5 (misidentification, = Aega komai Bruce, 996). Not Aega angustata.– Trilles & Justine, 2004: 220, figs 6, 7 (misidentification, = undescribed species). materiaL examined: Holotype, ♂ ( 4.3 mm), 5.5–6.5 km off Wattamolla, NSW, 34° 0’S, 5 ° ’E, 22 March 898, stn 57, 99– 08 m, coll. E.R. Waite on HMCS Thetis (AM G2 60). ♂ ( 7.0 mm), Bass Strait, 8 -HK- , stn 48/29, from Raja (NMV J8878). ♂ ( 7.5 mm), BSS stn 57 (NMV J8882). desCription: Body 3.7 times as long as greatest width, dorsal surfaces smooth or polished in appearance, widest at pereonite 5 or pereonite 6, lateral margins subparallel. Rostral point projecting anteriorly, not ventrally folded. Eyes large, not medially united, separated by about 30% width of head. Pereonite 1 and coxae 2–3 each with posteroventral angle rounded. Coxae 5–7 with entire oblique carina; posterior margins convex, posterolateral angle rounded. Pleon with pleonite largely concealed by pereonite 7; pleonite 4 with posterolateral margins extending clearly beyond posterior margin of pleonite 5; pleonite 5 with posterolateral angles free, not overlapped by lateral margins of pleonite 4. Pleotelson 0.9 times as long as anterior width, dorsal surface with longitudinal carina on distal third; lateral margins weakly convex, deeply serrate, posterior margin with distinct short median point, with 0 RS. Antennule peduncle articles 1 and 2 flattened, article 2 anterodistal lobe extending to end of article 3; articles 3 and 4 0.3 times as long as combined lengths of articles 1 and 2, article 3 3.1 times as long as wide; flagellum with 5 articles, extending to mid-point of eye. Antenna peduncle article 2 inferior surface without distinct longitudinal suture; article 5 flattened and expanded, 2.1 times as long as article 4 (in situ); flagellum with 8 articles, extending to posterior of pereonite . Frontal lamina flat, longer than greatest width, lateral margins converging posteriorly, anterior margin rounded, without small median point, posterior margin not abutting clypeus. Pereopod 1 basis .9 times as long as greatest width; ischium 0.5 times as long as basis, inferior margin with AppENdIx 2. ExtrA-lImItAl spEcIEs The species included here are some of those in need of at least partial redescription because of their similarity to New Zealand species in the body of the monograph. Some of these have been placed in synonymy with older names at some point. For most species the descriptive notes are based solely on the type material. 232 0 RS, superior distal margin with 2 RS; merus inferior margin convex and thickened, merus inferior margin with 2 RS (small), set as distal group, superior distal angle with 2 RS; carpus 0.7 as long as merus, inferior margin with 0 RS; propodus .3 times as long as proximal width, inferior margin with RS (distal), propodal palm simple, without blade or process, dactylus smoothly curved, .3 as long as propodus. Pereopod 3 ischium inferior margin with 3 RS, superior distal margin with RS; merus inferior margin with 5 RS (set as 3 + 2), set as two groups, superior distal margin with 2 acute RS; carpus longer than that of pereopod , with inferodistal lobe, inferodistal angle with RS, propodus with large club-shaped distal RS. Pereopods 5–7 inferior margins of ischium–carpus with long acute RS. Pereopod 6 basis 2.9 times as long as greatest width, inferior margins with 6 palmate setae; ischium 0.6 as long as basis, inferior margin with 5 RS (set loosely as , , 2 and ), superior distal angle with 5 RS, inferior distal angle with 8 RS; merus 0.7 as long as ischium, 2.0 as long as wide, inferior margin with 6 RS (set loosely as 3 and 3, 4 being submarginal), superior distal angle with 5 RS, inferior distal angle with 5 RS; carpus 0.9 as long as ischium, 3.6 times as long as wide, inferior margin with 4 RS (set as and 3), superior distal angle with 3 RS, inferior distal angle with 6 RS; propodus .0 as long as ischium, 6.8 times as long as wide, inferior margin with 3 RS (set as and 2), superior distal angle with slender seta, inferior distal angle with 4 RS. Penes short rectangular lobes; penial openings separated by % of sternal width, penial process 3.5 times as long as basal width. Pleopod 1 exopod .8 times as long as wide, distally broadly rounded, lateral margin straight, mesial margin weakly convex, with PMS on distal two-thirds; endopod .5 times as long as wide, distally narrowly rounded, lateral margin weakly concave, with PMS on distal half, mesial margin with PMS on distal one-third; peduncle .5 times as wide as long, mesial margin with 6 coupling hooks. Exopods of pleopods –3 each with distolateral margin not digitate. Uropod peduncle ventrolateral margin with 2 RS, posterior lobe about as long as endopod. Uropod rami with endopod and exopod co-planar, rami not extending beyond pleotelson, marginal setae in single tier, apices acute. Endopod apically not bifid, lateral margin proximally convex and distally convex, without prominent excision, proximal lateral margin with 0 RS,
