Baird, 1971
(
Fig. 5H
)
Diagnosis.
Sternoptyx pseudobscura
differs from congeners by the SAN distinctly elevated, positioned higher or near mid-trunk line; posterior anal-fin pterygiophores nearly as long as the anterior ones; 9–11 dorsal-fin rays; usually 29 vertebrae, occasionally 27, 28, 30 or 31 (Baird, 1971, 1986; Borodulina, 1978; Badcock, Baird, 1980;
Lima
et al.
, 2011).
Geographical distribution.
Circumglobal
in tropical and temperate waters, between 40ºN and 40ºS (Baird, 1971; Borodulina, 1977, 1978; Quéro
et al
., 1990b; Harold, 2003; Lima
et al.
, 2011; Sutton
et al.
, 2020; Love
et al
., 2021).
In
the
western Atlantic
, the species is reported from off
Canada
to
Brazil
, including the
Gulf of Mexico
and the
Caribbean Sea
(Baird, 1971; Uyeno, Aizawa, 1983; McAllister, 1990; Harold, 2003; Milkova
et al.
, 2016; Judkins, Haedrich, 2018; Ramírez
et al.
, 2019).
In Brazilian
waters,
S. pseudobscura
was previously reported off the northeastern coast and adjacent oceanic islands, and from
Bahia
to
Rio de Janeiro
States
, with additional records outside the
Brazilian
EEZ off the northeast and south regions (Baird, 1971; Borodulina, 1978; Menezes
et al.
, 2003; Braga
et al.
, 2007; Costa, Mincarone, 2010; Lima
et al.
, 2011; Eduardo
et al.
, 2018a, 2020a; Judkins, Haedrich, 2018).
The
species is reported here based on specimens collected between depths of 520 and
1,113 m
off
Paraíba
,
Pernambuco
, and
Rio Grande do Norte
States, including the seamounts, in addition to the
Fernando de Noronha Archipelago

.
