Amaryllididae Lowry & Stoddart View in CoL

Amaryllididae Lowry & Stoddart, 2002: 165 View in CoL .

Diagnosis. Head much deeper than long, with lateral cephalic lobe weak, midanterior notch present or absent. Epistome and upper lip fused. Mandible, left lacinia mobilis a stemmed serrate blade; accessory setal row well developed, usually with intermediate setae, with a large tuft of setae distally; molar a slightly setose flap with setose margins. Maxilla 1, outer plate with setal-teeth in a 6/5 arrangement, palp absent. Maxilliped, outer plate without distal or medial slender or robust setae; palp well developed, article 4 reduced. Gnathopod 1 simple, coxa vestigial, merus and carpus not rotated, posterior margin of propodus serrate, dactylus simple, without subterminal tooth. Gnathopod 2, posterodistal corner of propodus with medial and lateral robust setae. Pereopods 3–7 simple; propodus without posterodistal spur. Telson with slight to medium cleft.

Type genus. Amaryllis Haswell, 1879 View in CoL .

Generic composition. The family contains eight genera in two subfamilies: Amaryllidinae n.subfam. with Amaryllis Haswell, 1879 View in CoL ; Bamarooka View in CoL n.gen.; Erikus Lowry & Stoddart, 1987 View in CoL and Wonga View in CoL n.gen.; and Vijayiinae View in CoL n.subfam. with Bathyamaryllis Pirlot, 1933 View in CoL ; Devo View in CoL n.gen.; Pseudamaryllis Andres, 1981 View in CoL and Vijaya Walker, 1904 View in CoL .

Remarks. Amaryllidids are very distinctive amphipods. They are distinguished from other lysianassoid family groups by their head shape; maxilla 1 without a palp; extremely reduced gnathopod 1 coxa; and gnathopod 1 propodus with serrate posterior margin. Most are immediately recognizable by their very deep head shape with midanterior notch.
