Summary:Prometopa cedrici sp. nov. Figs 1-6 Holotype ♂? 4.5 mm, fully dissected and mounted in slides in Faure's liquid; RBINS, I.G. 31071 2 slides: IG 31071 / INV 83816A and IG 31071 / INV 83816B (Museum Brussels). R/V Polarstern , cruise ANTARKTIS- XXIII/8, Larsen B area, station 702-9 B_ South 65°57.85'S 60°28.42'W to 65°57.42'S 60°28.12'W, 12/01/2007, 215- 221 m, hard bottom with a lot of hydrocorals; gear: Agassiz trawl. Paratype ♀, 4.8 mm, partly dissected, dissected parts mounted on 2 slides, registration numbers: RBINS, IG 31071 / INV 83816B and INV 83816C (Museum Brussels), same locality as above. Etymology Dedicated to Cédric d'Udekem d'Acoz (Brussels), extremely careful taxonomist for amphipods and decapods. Description HABITUS. Dorsal outline spiky from peraeonite 1-5, the next four body segments reinforced dorsally, appearing 'double folded', with rounded outline. Suture between urosomites not clear. HEAD. A1 subequal to A2. A1 peduncle art. 1> art. 2, ratio art. 2:art. 3 = 2; art. 1 ordinary, without nasiform process; flagellum with 14 arts. A 2 art. 4> art. 5, flagellum with 8-9 arts. Mouthparts: Md molar small; palp longer than Md body, ratio art. 2:art. 3 = about 3, sparse and regular setation on art. 2, only one distal seta on art. 3. Mx1 palp with 2 arts. Mx2 IP about half length of OP, both with long setae distally, next to them some short ones. GNATHOPODS. Gn1 much smaller than Gn2. Cx1 semicircularly rounded distally. Basis robust and distally widening, on anterior margin long and short setae, on posterior one only short setae. Ischium longer than wide, with long setae distally. Merus distoposteriorly lengthened and beset with short and stiff setae, also two long setae and two spines distally. Carpus triangular, beset with long setae on anterior and posterior margin. Propodus 3-4 times as long as wide, on all margins some long setae, palm weakly rounded without any palmar corner, but defined by 5 spines. Gn2 strong. Cx2 tongue-shaped, about twice as long as wide, with nearly parallel margins. ...
