Phosichthys Hutton, 1872

Diagnosis. Phosichthys is a monotypic genus distinguished in the Phosichthyidae by the presence of two ORB (one anterior to eye and one mid-ventral or posterior to it); eyes not tubular; lower jaw teeth uniserial; teeth on vomer and palatine; dorsal-fin origin posterior to pelvic-fin origin; dorsal adipose fin present; dorsal-fin base and dorsal adipose-fin base much shorter than anal-fin base; 12–13 dorsal-fin rays; 23–26 anal-fin rays; 15–18 gill rakers; IC 57–58; AC 16–18 (Schaefer et al., 1986b; Kenaley, Stewart, 2015d; Sutton et al., 2020).

( Fig. 6B )

Diagnosis. Same as for the genus.

Geographical distribution. Cincumglobal in the Southern Hemisphere, except the eastern Pacific Ocean (Quéro et al., 1990c; Hutchins, 2001; Kenaley, Stewart, 2015d;

Balushkin, 2017; Sutton et al., 2020). In the western Atlantic, the species was recorded off Brazil (from Bahia to Rio Grande do Sul States), Uruguay, and off the Malvinas

Islands (Parin et al., 1974; Figueiredo et al., 2002; Menezes et al., 2003; Bernardes et al.,

2005; Braga et al., 2007; Haimovici et al., 2008; Nión et al., 2016). Phosichthys argenteus is reported here based on one specimen collected at 63 m depth off Rio Grande do Norte

State, near the seamounts ( Fig. 7A ).

Specimen examined. 1: NPM 4560, 1 (64 mm), AB2#35.
