Description. Based on holotype female, 20.5 mm, NMV J3765. 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 strong midanterior angle (lateral view). Mandible lacinia mobilis a stemmed, distally-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 deeply notched.

Gnathopod 1 carpus subequal in length to propodus; propodus, posterior margin without robust setae. Gnathopod 152 Records of the Australian Museum (2002) Vol. 54 2 palm slightly   acute, with 3–4 lateral robust setae, 4 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, without notch. 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 37%).

Male (sexually dimorphic characters). Based on male, 5.8 mm, AM P37102 View Materials (probably not fully mature). Antenna 1 flagellum with callynophore. Antenna 2 flagellum with calceoli. Mandible palp article 2 with 3 posterodistal setae.

Etymology. Named for Stephen Keable in recognition and appreciation of his meticulous work in producing illustrations of amphipods.

Remarks. Amaryllis keablei   is similar to other Amaryllis species   with a serrate posterior margin on epimeron 3, such as A. carrascoi   , A. croca   , A. dianae   and A. migo   . It is most similar to A. croca   in that the serrations extend to the posteroventral corner. Amaryllis keablei   differs from A. croca   in having a strong mid-anterior angle on the epistome/ upper lip, a small medial spine on pedunclar article 1 of antenna 1, no posterodistal setae on mandibular palp article 2 of the female and 3 to 4 lateral robust setae on the palm of female gnathopod 2.

Distribution. Southeastern and southern Australia, from Port Stephens on the east coast to the South Australian Gulfs; 2–60 m depth.
