Devo n.gen.

Diagnosis. Head with rostrum cone-shaped; eye, when present, oval. Antenna 1 peduncular article 1 ball-shaped proximally; peduncular article 2 long; callynophore absent in female, present in male. Antenna 2 flagellum about as long as that of antenna 1 in female, longer than body in male. Mandible palp article 3 without proximal A3-seta. Pereopod 4 coxa with anterior margin slightly obtuse, posterior margin rounded or with anterior margin slightly obtuse, posterior margin straight. Uropod 3 rami with plumose setae in male, with or without plumose setae in female; outer ramus 1-articulate or 2-articulate.

Type species. Devo grahami n.sp.

Species composition. Devo contains four species: D. conocephala (K.H. Barnard, 1925) , D. dubuc n.sp., D. grahami n.sp. and D. rostrata ( Chevreux, 1911) .

Etymology. The name Devo is an allusion to a recent American music group of the same name, whose members wore peculiar cone-shaped head coverings.

Remarks. Devo forms a distinctive group of species, distinguished from other vijayiines by their strongly flared fourth coxae and well-developed rostrums. Species in the genus Devo appear to be more adapted for a pelagic lifestyle than are other amaryllidids.

Distribution. Eastern North and South Atlantic Oceans, southwestern Indian Ocean and western South Pacific Ocean; 500–1840 m depth (see Fig. 70).
