Neognathophausia gigas ( Willemoës-Suhm, 1873)

Material examined (non-type only) ANGOLA BASIN • 1 imm. (BL = 40 mm); 22°20.640′ S, 3°23.567′ E to 22°26.150′ S, 3°27.046′ E;

bottom depth 5161–5162 m; 10 Jul. 2000; DIVA-1 exped., #321; Agassiz Trawl; ZMH 58243 .

Type locality

Implicitly defined by monotypy. Willemoës-Suhm (1873, 1875) based the first description on a single male specimen caught between Bermuda and the Azores, 38°22′ N, 37°21′ W, depth 2200 fathoms (4023 m).

Distribution

According to San Vicente (2016) this meso- to bathypelagic species shows a panoceanic distribution, latitudinal range 66º N– 74º S, depth range 650–4023 m. This species has been reported by Illig (1930) as the synonym Gnathophausia drepanephora Holt & Tattersall, 1905 , from material taken by the “Valdivia” Expedition in the Angola Basin. See Discussion for a biogeographical assessment of the new record from 5161–5162 m bottom depth in the Angola Basin.
