Boreomysis bispinosa O.S. Tattersall, 1955

Material examined (non-types only) ANGOLA BASIN • 1 imm. (BL = 8.3 mm, eyes missing); 17°4.935′ S, 4°40.805′ E to 17°07.454′ S,

4°42.276′ E; bottom depth 5460– 5460 m; 25 Jul. 2000; DIVA-1 exped., #344; epinet of epibenthic sledge; ZMH 58248 • 1 ♀ ad. (estimated BL = 12.6 mm, cephalothorax and exuvia); 16°16.989′ S, 5°27.279′ E to 16°19.280′ S, 5°27.205′ E; bottom depth 5430–5433 m; 28 Jul. 2000; DIVA-1 exped., #348; supranet of epibenthic sledge; ZMH 58249 .

Type locality

Not stated by O.S. Tattersall (1955). On page 14 she indicated a “female type ” taken off Cape Town, depth 1350 – 1250 m, and a “male type ” NE of St. Helena, depth 1450 – 700 m. A rough estimate by the present author suggests that the stations are from 34° S, 17° E and 15° S, 5° W, respectively.

Distribution

Previously reported from the Atlantic Ocean and from the Atlantic sector of the Southern Ocean, 51° N– 54° S, 36° W– 17° E (O.S. Tattersall 1955; Mauchline & Murano 1977; Hargreaves 1997; Wittmann et al. 2004; Petryashov 2005 b; San Vicente 2011). The animals were sampled with benthic as well as pelagic gears. The here documented records in the SE-Atlantic at 16– 17° S, 5° E are within the already known geographical range, while the bathymetrical range of 700–4050 m is now extended down to 5430–5460 m (see also Discussion).
