Type locality

Not stated by Holt & Tattersall (1905). Upon first description, they reported material from seven stations at the NE-Atlantic slope, depth 181̄382 fathoms (331̄699 m). A rough estimate by the present author suggests that the stations are in the range of 50– 54° N, 10– 13° W.

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 16̄ 22° S, 3̄ 5° E, depth 5179̄ 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).
