distribution
Distribution Previously reported from the North Atlantic and Mediterranean, 34 – 61 ° N, 72 ° W – 14 ° E, depth 200 – 2900 m (Hansen 1908, 1927; W. M. Tattersall 1909, 1951; Colosi 1929; Lagardère 1972; Nouvel & Lagardère 1976; Mauchline 1986; Cartes & Sorbe 1995; Cartes et al. 2004; Vanquickelberghe 2004; Fanelli 2007; Petryashov 2009; San Vicente 2010, 2017; Sorbe & Elizalde 2013). Sorbe & Elizalde (2013) considered this species as part of the suprabenthic fauna. The here documented records in the SE- Atlantic at 16 ̄ 22 ° S, 3 ̄ 5 ° E, depth 5179 ̄ 5434 m, represent large extensions of the known geographical as well as bathymetrical ranges (see also Discussion). Statoliths Statoliths mineralized with fluorite; diameter 124 μm in the ♂ ad. 16 mm, vs 89 μm in the ♀ subad. 14.5 mm, and 62 μm in the imm. 9.0 mm (2 statoliths per specimen examined).

Material examined (non-types only) ANGOLA BASIN • 1 ♂ ad. (BL = 16 mm, in 2 parts); 22 ° 19.978 ′ S, 3 ° 18.342 ′ E to 22 ° 20.249 ′ S, 3 ° 18.439 ′ E; bottom depth 5179 – 5180 m; 9 Jul. 2000; DIVA- 1 exped., # 318; ZMH 58261 • 1 imm. (BL = 9.0 mm, in 2 parts), 1 juv. (BL = 6.5 mm); 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 58259 • 2 ♀♀ imm. (BL = 6.5 – 8.3 mm); same collection data as for preceding; ZMH 58260 • 1 ♀ subad. (BL = 14.5 mm); 16 ° 13.329 ′ S, 5 ° 26.837 ′ E to 16 ° 14.820 ′ S, 5 ° 26.702 ′ E; bottom depth 5433 – 5434 m; 29 Jul. 2000; DIVA- 1 exped., # 350; supranet of epibenthic sledge; SMF 55191. Type locality Not stated by Holt & Tattersall (1905). Upon first description, they reported material from seven stations at the NE-Atlantic slope, depth 181 ̄ 382 fathoms (331 ̄ 699 m). A rough estimate by the present author suggests that the stations are in the range of 50 – 54 ° N, 10 – 13 ° W.
