Chauliopleona hastata (Hansen, 1913) (Figures 1H–M, 11–13, 17A, 18) Leptognathia hastata Hansen, 1913: 79–80, pl. VII figs. 7a–g Leptognathia hastata : Nierstrasz 1913: 30; Stephensen 1932: 348; else, see Sieg 1983 Chauliopleona hastata : Guerrero-Kommritz 2005: 1191–1195, figs. 7–8; else, see Anderson 2013 Diagnosis Cephalothorax 1.2 times ltb.

Pereopods 1–3 basis margins smooth; carpus and propodus inferior spinules weak. Pereopod-1 dactylus and unguis short, about 2/3 length of propodus. Pereopods 2–3 carpus without distomedial seta.

Ovigerous/post ovigerous female: body length 2.55–3.27 mm. Preparatory male: body length 2.20–3.15 mm. Distribution records from the AFEN, BIOICE and BIOFAR area 33 records from AFEN surveys: 31 from the Faroe-Shetland Channel, 1026–1741 m, one from the Norwegian Basin 2064 m, one from the West Shetland Slope, 400 m. One record from BIOFAR: Norwegian Basin, 1261 m. Eleven records from BIOICE: two from Denmark Strait, 1012–1146 m, one from the Irminger Basin, 1326 m, five from the Iceland Plateau, 1300–1646 m, one from the Jan Mayen Ridge, 1529 m, and two from the Norwegian Basin, 1639–1994 m; almost all bottom temperatures are negative, ranging from −0.9°C to −0.6°C, but with the exception of Irminger Basin Stn 3187, 3.99°C. A variety of sediments types are recorded including ‘very fine sand’, ‘sandy mud’, ‘silt’ and ‘gravelly sandy silt’. Also in the area: Ingolf Stn 102, 1412 m, and Stn 125, 1372 m (Hansen 1913); overall depth range 400?– 1994 m. Distribution elsewhere Fifteen records from the deep Norwegian Basin (NORBI survey, Bird unpub.) 2470– 3709 m. Remarks This species is recognised by its stout cheliped carpus (1.6 times ltb, Figure 12J) with its deep and rounded inferior shield, while its pereopods 1–3 (Figure 13A–C) are more robust compared to those of C. amdrupii and C. armata . The pleonal sternites are also lower than in C. armata and C. amdrupii . The cheliped shown by Guerrero- Kommritz (2005, fig. 7b, f) based on non-type material from the Greenland Sea at 188–191 m is far more massive and angular than those illustrated here from the cotype and new topotypical material, and is more similar to that of the new genus described below. Similarly, his drawing of the pereopod-5 (Guerrero-Kommritz 2005, fig. 8l) suggests that it may not be C. hastata . Another Atlantic species, C. amftae from the abyssal Angola Basin, also has a robust cheliped but this taxon differs from C. hastata at least by having a proportionately longer cephalothorax (> pereonites 1–2), a small protuberance/apophysis on the cheliped merus and fewer pleopodal setae. Chauliopleona hastata is a cold-water species with an overall recorded depth range of 400–3709 m, i.e. it is primarily characteristic of the Arctic area of the Norwegian Sea, but there is a single, possibly spurious, record from the West Shetland Slope at 400 m (SEA-4 Stn 57075#1). The record of a preparatory male from the Irminger Basin (BIOICE Stn 3187) also looks anomalous but the specimen appears to have characters consistent with C. hastata , such as its robust cheliped (Figure 17A). : 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 1530-1535, DOI: 10.1080/00222933.2015.1005715, http://zenodo.org/record/3999694 : {"references": ["Hansen HJ. 1913.

A variety of sediments types are recorded including ‘very fine sand’, ‘sandy mud’, ‘silt’ and ‘gravelly sandy silt’. Also in the area: Ingolf Stn 102, 1412 m, and Stn 125, 1372 m (Hansen 1913); overall depth range 400?– 1994 m.
