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

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.
