Urosome segments 2–3 fused. Head without rostrum and postantennal corners, no eyes. Mandible palp present, 3-articulate. Gnathopods 1–2 subchelate; peraeopods 6–7 also clearly subchelate. Uropods with rami well-developed, with many spines. Etymology The species is named after POJ’s youngest daughter. Material examined The holotype was collected 4 Jun.1983 at station 83.06.4.1, in the North Atlantic Ocean, southwest of the Faroes and northeast of Rockall (at position 59 o 40.4’N, 09 o 20.6’W). The specimen was sampled at a depth of 1414 meter where the in situ temperature was measured to 4.5 o C. No further material was found. The holotype is deposited in the collections of Zoological Museum in Bergen, Norway under registration no. ZMBN 99136. Description Holotype 4 mm, immature (no external gender characteristics observed). BODY. Sparsely covered with setae that are attached to crown-like pegs. Peraeon segment 1 dorsally smooth; peraeon segments 2–7 and pleon segments 1–4 each with one dorsal tooth. Urosome segments 2–3 fused. Coxal plates 1–5 all biacuminate, decreasing in length posteriorly. HEAD. Subequal to peraeon segments 1+2, no distinct rostrum or postantennal corners; eyes absent or at least indistinct in alcohol, an invagination at the basis of antenna 2. Antenna 1, peduncle article 1 broader than article 2 and 3; peduncle article 2 is 2x as long as article 1; peduncle article 3 is 0.5x art 1; accessory flagellum is 1-articulate with three apical setae; flagellum slightly longer than peduncle articles 1–3 combined; flagellum 12-articulate.Antenna 2 is 1.5x antenna 1. Antenna 2, peduncle articles 4 and 5 long, subequal; flagellum shorter than article 5; flagellum 6-articulate. MOUTHPARTS. Upper lip circular; lower lip inner lobe 3/4 of outer; mandible with lacinia mobilis as long as incisor, both armed with denticles; 7–8 ... |
