Description. Based on holotype female, 16.5 mm, AM P37378 View Materials . Head much deeper than long, anterior margin with notch extended into a slit; rostrum absent; eye present, elongate, reniform. Antenna 1 peduncular article 1 not ballshaped proximally, distal margin with small medial spine; peduncular article 2 medium length; flagellum without callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1, without calceoli. Mouthpart bundle subconical. Epistome/upper lip with moderate midanterior angle with small depression above angle (lateral view). Mandible lacinia mobilis a stemmed, distally-cusped blade; accessory setal row with intermediate setae; palp article 2 with 3 posterodistal setae, article 3 without A3- seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus shorter than propodus; propodus, posterior margin without robust setae. Gnathopod 2 palm slightly   acute, without lateral robust setae, 2–3 medial robust setae. Pereopods 3 and 4 merus and carpus without setal fringe. Pereopod 4 coxa with anterior and posterior margins subparallel, anteroventral corner rounded. Pereopods 5–7 with distal articles elongate, dactyls short and stocky. Pereopod 5 basis expanded posteriorly, rounded. Pereopod 7 basis subrectangular, posteroventral corner subquadrate, posteroventral margin straight.

Epimeron 3 posterior margin serrate, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 17 robust setae; outer ramus without large spines between robust setae. Uropod 2 inner ramus slightly   constricted. Uropod 3 rami lanceolate; without plumose setae; outer ramus 1-articulate. Telson moderately cleft   (about 41%).

Male (sexually dimorphic characters). Based on paratype male, 6.0 mm, AM P37380 View Materials (probably not fully mature). Antenna 1 flagellum with callynophore. Antenna 2 flagellum with calceoli. Gnathopod 2 palm with 1 lateral robust seta, without medial robust setae.

Etymology. Named for Diana Jones, carcinologist at the Western Australian Museum, in appreciation of her generous help with collections of Western Australian amphipods.

Remarks. Amaryllis dianae   is most similar to other Amaryllis species   with a serrate posterior margin on represent 0.5 mm.

epimeron 3, such as A. carrascoi   , A. croca   , A. keablei   and A. migo   . Amaryllis dianae   , A. carrascoi   and A. migo   all have a notch above the posteroventral corner of epimeron 3; in A. croca   and A. keablei   the serrations extend to the posteroventral corner. The posteroventral corner of pereopod 7 is rounded in A. migo   , subquadrate in A. dianae   and subquadrate with a distinct notch in A. carrascoi   .

Distribution. Southern and southwestern Australia; 3–219 m depth.
