Description. Based on holotypefemale, 7.7 mm, AM P36872. Head much deeper than long, anterior margin with notch; rostrum present, cone-shaped; eye present, elongate, Figure 71. Devo dubuc n.sp., holotype female, 7.2 mm, NMV J48795; paratype male, 7.5 mm, NMV J48794; * paratypeimmature male, 7.4 mm, NMV J48793; off Cape Tourville, Tasmania. Scalesfor 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 paratypeimmature male, 7.4 mm, NMV J48793; off Cape Tourville, Tasmania. Scalesrepresent 0.2 mm. obtuse, posterior margin straight, anteroventral corner subquadrate. Pereopods5–7 with distal articles elongate, dactyls long and slender. Pereopod5 basis expanded posteriorly, rounded. Pereopod7 basis subrectangular, posteroventral corner rounded, posteroventral margin curved. Figure 72. Devo dubuc n.sp., holotype female, 7.2 mm, NMV J48795; paratype male, 7.5 mm, NMV J48794; * Figure 73. 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 paratypemale, 9.3 mm, AMP36873. 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.
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 grahamiis very similar to D. dubucbut 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 grahamihas been collected on fine and coarse sediment bottoms.
Distribution. Southeastern Australia, Tasman Sea; 549– 1840 mdepth.
