Chauliopleona armata (Hansen 1913) (Figures 1B–G, 5–7, 18) Leptognathia armata Hansen, 1913: 80–81, pl. VIII figs. 1a–f Leptognathia armata : Nierstrasz 1913: 30; Stephensen 1932: 347; Stephensen 1943: 36, 63; Holdich and Bird 1985: 443 table 1; else, see Sieg 1983 Chauliopleona armata : Guerrero-Kommritz 2005: 1188–1191, figs. 5–6; else, see Anderson 2013 Diagnosis Cephalothorax 1.3–1.6 times ltb. Pereonites all shorter than broad; with parallel lateral margins. Pleon shorter than cephalothorax, without posteriodorsal protuberance; pleonites 1–4 sternite with subtriangular sternal process. Antennule article-1 (1.2 times) longer than rest of antennule. Maxilliped basis with long seta. Cheliped merus without inferior protuberance; carpus fairly stout, 1.6 times ltb, inferior shield shallow (aspect ratio ≈ 0.3), rounded, distal margin not angular; fixed finger with four teeth; dactylus superior margin smooth. Pereopods 1–3 basis margins smooth; propodus inferior spinules numerous, moderate or robust. Pereopods 2–3 carpus without distomedial seta. 1 Pereopods 4–6 ischium with two short setae. Uropod exopod about half as long as endopod segment-1; endopod> three times longer than peduncle. Material examined BIOICE stns.

AFEN Stn. One individual, 54591#1; one non-ov. ♀, 54600#2. Co-type. Non-ov. ♀, Ingolf Stn 22. Other material. SMBA stns: one individual (ind.), ES105; four ind., ES218; two ind., SBC61; two ind., one ind., SBC68; SBC166; one ind., SBC216. INCAL stns: one ind., CP01; two ind., CP02; one ind., DS01. Size Non-ovigerous female. Body length 2.28–3.64 mm, cf. 3.6 mm as measured by Hansen (1913) or 3.8 mm by Guerrero-Kommritz (2005). Ovigerous female: body length 2.96 mm. Preparatory male. Body length 2.72–3.44 mm, cf. 3.3 mm Hansen (1913). Distribution records from the AFEN, BIOICE and BIOFAR area Eleven from AFEN: two from North Feni Ridge, 1600–2000 m, eight from the northern Rockall Trough, 1859–1871 m, and one from the Hebrides Slope, 1800 m. Ten records from BIOICE: all from the Iceland Basin, 1333–2400 m; with positive bottom temperatures 2.1–3.99°C and a variety of sediment types including ‘silty sand’, ‘shell debris’, ‘silt’ and ‘muddy gravel’. Distribution elsewhere The type locality is the Davis Strait, 2702 m, and southwest of Cape Farewell, 3474 m (Hansen 1913). I have 51 records from the northeast Atlantic, extending from the Iceland Basin (deeper and further south than the BIOICE area) to the southern Bay of Biscay, including the South Feni Ridge, Rockall Trough, Porcupine Seabight, Celtic and Armorican Slopes, and Biscay Abyssal Plain, 1180–4823 m (SMBA, IOS, COB, Chain-106). Some of these were reported by Holdich and Bird (1985). These data are available from the author on request. Remarks A significant problem in assessing any new records of C. armata is that the original type material consists of only two specimens (Figure 1B–G) and this shows some differences from the specimens illustrated here that have a slightly shorter cephalothorax and somewhat weaker propodal spinules on pereopods 1–3 (Figure 7A–C). If these new records are genuine, Chauliopleona armata appears to be a eurybathic species, inhabiting both bathyal (200–2000 m) and abyssal zones (2000–6000 m). However, it is almost certain that the records of C. armata outside of the Atlantic Margin study area (see above) refer to more than one species, and the material needs re-examination. : Published as part of Bird, Graham John, 2015, Tanaidacea (Crustacea: Peracarida) of the northeast Atlantic: Chauliopleona Dojiri and Sieg, 1997 and Saurotipleona n. gen. from the ' Atlantic Margin', pp. 1507-1547 in Journal of Natural History 49 (25) on pages 1519-1524, DOI: 10.1080/00222933.2015.1005715, http://zenodo.org/record/3999694 : {"references": ["Hansen HJ. 1913.
