Eustomias braueri Zugmayer, 1911

( Fig. 15B )

Diagnosis. Eustomias braueri differs from congeners by the presence of 9–16 pectoral-fin rays; 8 pelvic-fin rays; chin barbel length approximately equal to head length, 12– 17% SL; one ovoid terminal bulb at the chin barbel with two anterior filaments; chin barbel stem darkly pigmented; a series of luminous spots on lower side of body that resembles large photophores; lower jaw about as long as upper jaw and not upturned at tip; wide ventral groove extending from isthmus to behind pectoral-fin base present; preorbital and suborbital organs absent (Morrow, Gibbs, 1964; McEachran, Fechhelm, 1998; Sutton et al., 2020).

Geographical distribution. Atlantic and western North Pacific oceans, between 40ºN and 30ºS (Morrow, Gibbs, 1964; Parin, Pokhilskaya, 1974; Bekker et al., 1975; Vinnichenko, 1997; McEachran, Fechhelm, 1998; Tatsuta et al., 2014; Sutton et al., 2020). Menezes et al. (2003) included the species in a list of Brazilian marine fishes based on Morrow , Gibbs (1964), but that record is outside the country’s EEZ, off the northeastern region. Melo et al. (2020: 208), in turn, regarded the species as “not confirmed” in Brazil. Therefore , occurrence of E. braueri is confirmed in the Brazilian EEZ based on one specimen collected off Pernambuco State, at 680 m depth ( Fig. 14B ) .

Specimen examined. 1: NPM 4816, 1 (56 mm), AB2#16.
