| Summary: | ANCORABOLINA BELGICAE SP. NOV. Type locality: North-east Atlantic Ocean, Porcupine Seabight, Boxcore Bbc 01-1205 during Belgica Cruise 01/12, 51°25.9290′N, 11°46.2717′W, 880 m, collected on 7.v.2001, sample of underlying sediment [sediment covered with dead fragments of the cold-water coral Lophelia pertusa (Linnaeus, 1758)]. Material examined: From type locality: Female holotype (coll. no. COP 7695 /a–n) dissected on 14 slides. Male unknown. Etymology: The species is named in honour of the crew of RV BELGICA. Description: Female: Habitus (Fig. 1A) long and slender. Total body length: 342 Mm (measured from tip of rostrum to posterior end of furcal rami). Rostrum (Fig. 2B) fused to cephalothorax and elongate, tip reaching distal end of first antennular segment, with paired sensilla distally. Cephalothorax anteriorly slightly constricted, forming a ‘peak’ as described by George (2006b). Cephalothorax with sensilla and pores as figured. Posteriorly with paired lateral processes, which are strongly cuticularized and curved backwards. Posterior margin of cephalothorax with four sensillate processes. Free body somites 1–4 and anterior somite of genital double-somite with a single mediodorsal tube pore. Free body somites 1–2 with four sensillate projections at their posterior margins. Free body somites 3–4 with inner pair of small processes and outer pair of sensillate processes. Both somites of genital double-somite and following urosomite with several small projections and sensilla at their posterior margins. Posterior margin of penultimate urosomite serrate. Telson broader than long, trapezoid in lateral view (Fig. 6C), anal operculum with row of spinules. Furcal rami (Figs 1B, 6A, C) long and slender, about 6.5 times as long as wide, with seven setae: I and II inserted closely together at posterior third of lateral margin; III inserted subapically; IV, V, and VI inserted apically; IV and V fused, V longest; VII inserted dorsally at distal margin. Outer margin with tube pore proximally. Furcal rami inserted at outer ... |
