Scales for A1, A2 represent 0.2 mm; remainder represent 0.1 mm . oval. Antenna 1 peduncular article 1 ball-shaped proximally, distal margin with well-developed medial spine; peduncular article 2 long, length 5× breadth; flagellum without callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1, without calceoli. Mouthpart bundle subquadrate. Epistome/upper lip almost straight (lateral view). Mandible lacinia mobilis a stemmed distolaterally cusped blade; accessory setal row with intermediate setae; palp article 2 without posterodistal setae, article 3 without A3-seta. Maxilliped outer plate with distal margin smooth, medial margin without notch. Gnathopod 1 carpus longer than propodus (1.3×); propodus, posterior margin with robust setae. Gnathopod 2 palm acute, without lateral robust setae, 1 medial robust seta. Pereopods 3 and 4 merus and carpus without setal fringe. Pereopod 4 coxa with anterior margin slightly paratype immature male, 7.4 mm , NMV J48793 ; off Cape Tourville , Tasmania . Scales represent 0.2 mm . obtuse, posterior margin straight, anteroventral corner subquadrate . Pereopods 5–7 with distal articles elongate, dactyls long and slender. Pereopod 5 basis expanded posteriorly, rounded. Pereopod 7 basis subrectangular, posteroventral corner rounded, posteroventral margin curved . Figure 72 .

Devo grahami n.sp. , whole animal: paratype immature male, 7.0 mm, AM P36877; Ƌ : paratype mature male, 9.3 mm, AM P36873; remainder: holotype female, 7.7 mm, AM P36872; east of Broken Bay, NSW. Scales represent 0.1 mm. Figure 74 . Devo grahami n.sp. , holotype female, 7.7 mm, AM P36872; paratype mature male, 9.3 mm, AM P36873; paratype immature male, 7.0 mm, AM P36877; east of Broken Bay, NSW. Scales for P3, 4 represent 0.2 mm; remainder represent 0.1 mm. Epimeron 3 posterior margin smooth, with notch immediately above acute posteroventral corner. Uropod 1 peduncle dorsolateral margin with 12 robust setae; outer ramus without large spines between robust setae. Uropod 2 inner ramus moderately constricted. Uropod 3 rami lanceolate; with a few plumose setae; outer ramus 2- articulate. Telson slightly cleft (about 30%). Male (sexually dimorphic characters). Based on paratype male, 9.3 mm , AM P36873. Antenna 1 flagellum with callynophore, with calceoli. Mandible palp article 2 with 11 posterodistal setae. Pereopods 3 and 4 merus and carpus with setal fringe. Uropod 3 rami with plumose setae . Figure 75 . Devo grahami n.sp. , holotype female, 7.7 mm, AM P36872, east of Broken Bay, NSW. Scales represent 0.2 mm. Etymology . Named for Ken Graham, fisheries biologist on the FRV Kapala , who helped immensely over the years in collecting amphipods and other invertebrates during the cruises of the Kapala . Remarks . Devo grahami is very similar to D. dubuc but is distinguished by the notch on the anterior margin of the head not extended into a slit, and by plumose setae present on uropod 3 of the female. Habitat . Devo grahami has been collected on fine and coarse sediment bottoms. Distribution . Southeastern Australia , Tasman Sea; 549– 1840 m depth.
