Description. Based on holotype female, 8.9 mm, AM P37169 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 without a medial spine; peduncular article 2 medium length; flagellum with callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1, without calceoli. Mouthpart bundle subconical. Epistome/upper lip with broad midanterior bulge (lateral view). Mandible lacinia mobilis a stemmed, distally-cusped blade; accessory setal row with intermediate setae; palp article 2 with 7 posterodistal setae, article 3 without A3-seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus shorter than propodus (0.75×); 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 curved.

Epimeron 3 posterior margin smooth, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 9 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 40%).

Male (sexually dimorphic characters). Based on paratype male, 5.5 mm, AM P37170 View Materials . Antenna 1 flagellum with calceoli. Antenna 2 flagellum with calceoli. Mandible palp article 2 with 5 posterodistal setae. Gnathopod 2 palm without lateral robust setae.

Etymology. The species is named for the wooden barque Olinda, which sank in 1852 off Eddystone Point, Tasmania, while carrying a cargo of timber and potatoes from Hobart to Melbourne.

Remarks. Amaryllis olinda   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 ( A. brevicornis   , A. kamata   , A. moona   , A. quokka   ). It has a curved posteroventral margin on the basis of pereopod 7, similar to A. moona   and A. quokka   . It differs from these two species in having gnathopod 1 carpus shorter than the propodus.

Habitat. Amaryllis olinda   has been collected from coarse sediments.

Distribution. Tasmania, Australia; 16–49 m depth.
