Description. Based on holotype female, 9.2 mm, AM P37107 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 2 posterodistal setae, article 3 without A3- 150 Records of the Australian Museum (2002) Vol. 54 seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus subequal in length to propodus (0.9×); propodus, posterior margin without robust setae. Gnathopod 2 palm slightly   acute, with 1 lateral robust seta, 1 medial robust seta. 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 rounded posteriorly, posteroventral corner rounded, posteroventral margin straight.

Epimeron 3 posterior margin smooth, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 8 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 43%).

Male (sexually dimorphic characters). Based on paratype male, 6.2 mm, AM P 37108 View Materials .Antenna 1 flagellum with callynophore, with calceoli. Antenna 2 flagellum with calceoli. Mandible palp article 2 with 9 posterodistal setae. Gnathopod 2 palm with no lateral robust setae and 1 medial robust seta   .

Etymology. The specific name is contrived and has no special meaning.

Remarks. Amaryllis kamata   belongs to the group of species with a smooth posterior margin on epimeron 3 and a rounded posteroventral corner on the basis of pereopod 7. Within this group it is most similar to A. brevicornis   but differs in the shape of the epistome/upper lip and the length of the gnathopod 1 carpus.

Habitat. Amaryllis kamata   is known from sand and mud bottoms off the New South Wales coast. It is the deepestoccurring species (50 to 525 m depth) of Amaryllis   known from Australian waters.

Distribution. Southeastern Australia; 40–523 m depth.
