Tanaidacea (Crustacea, Peracarida) of the North-east Atlantic: the Agathotanaidae of the AFEN, BIOFAR and BIOICE projects, with a description of a new species of Paragathotanais Lang Author Bird, Graham J text Zootaxa 2010 2730 1 22 journal article 46897 10.5281/zenodo.200143 77534a09-c17e-4b60-8b87-ab041da548ff 1175-5326 200143 Paragathotanais robustus Bird & Holdich, 1988 Fig. 2 E Bird & Holdich (1988) : 1605–1608 , figs 2b, h, i, 6–7. Guerrero-Kommritz (2003) : 3. Larsen (2006): 108, 120. Identification reference . Bird & Holdich (1988) . Distribution records from the AFEN, BIOFAR & BIOICE surveys. Recorded from 22 BIOICE stations, from the Denmark Strait, Iceland Basin, and Irminger Basin, at depths 256–1533 m . Not recorded in the AFEN and BIOFAR material. The highest count was 123 specimens from BIOICE sample 2475, Iceland Basin, at 842 m . Distribution elsewhere. From North Feni Ridge to the South Biscay Slope, at depths 1279–2246 m ( Bird & Holdich 1988 ). Remarks. Care is needed to distinguish this species from P. nanus when they co-occur in samples (see above) but the broader pleon and more pointed pleotelson are diagnostic characters ( Fig. 2 E). As with the previous two agathotanaid species, the recorded upper bathymetric limit of P. robustus is now much shallower, raised from 1279 m (see above) to 256 m . A similar range of benthic temperatures of 2–4o C is also evident.
