Distribution. First record of Coryphaenoides rudis in the WSA. Collected from off Bahia Espírito Santo and Rio de Janeiro, at depths from 1334 to 2271. It was described from the South Pacific (28°33’ S, 177°50’ W) and is widespread in the Indian and central Atlantic ( Günther 1887; Shcherbachev & Iwamoto 1995; Iwamoto 2002). Cohen et al. (1990) referred to it as a possible junior synonym of P. paradoxus.

Remarks. This species was mistakenly referred to by Costa et al. (2007) as Coryphaenoides cf. longicirrhus (Gilbert 1905) . Coryphaenoides rudis can be distinguished from C. longicirrhus by the mandibulary teeth in two or more rows (vs. mandibulary teeth in a single row).
