Amaryllis keablei n.sp. , holotype female, 20.5 mm, NMV J3765, Bass Strait; male, 5.8 mm,AM P37102; Twofold Bay, NSW. Scales for A1, 2 represent 0.5 mm; remainder represent 0.1 mm. Type locality . 23 km east of Cape Rochon , Three Hummock Island , central Bass Strait , Tasmania , Australia , 40°22.2'S 145°17'E , 40 m depth . 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. Figure 18 . Amaryllis keablei n.sp. , holotype female, 20.5 mm, NMV J3765, Bass Strait. Scales represent 0.5 mm. 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 (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.
