STOMIIDAE

The Stomiidae is a family of meso- and bathypelagic fishes with a wide distribution in the Atlantic, Indian, Pacific, and Southern oceans (Fink, 1985; Gon, 1990c; Duhamel et al., 2014; Kenaley, Stewart, 2015e). It is the most diverse family of the Stomiiformes , with a total of 28 genera and about 319 valid species (Fink, 1985; Nelson et al., 2016; Fricke et al., 2022). The family is generally regarded as monophyletic (e.g., Fink, 1985; Nelson et al., 2016; Kenaley, Stewart, 2015e), but subfamilies within the assemblage are likely not monophyletic and are sometimes treated as distinct families (e.g., Harold, 2003; Parin, Borodulina, 2003; Prokofiev, 2014, 2015, 2020). Here we follow Kenaley, Stewart (2015e), who provisionally recognized six subfamilies of stomiid fishes: Astronesthinae , Chauliodontinae , Idiacanthinae , Malacosteinae , Melanostomiinae , and Stomiinae . In general, members of the Stomiidae have an elongated body, mouth large to extremely large, teeth often fang-like, sometimes small, no true gill rakers in adults, two rows of photophores along the body, and a chin barbel often ornate and associated with the hyoid apparatus present in most species (Kenaley, Stewart, 2015e; Nelson et al., 2016).

At least 50 species of the Stomiidae were previously reported in Brazillian waters, in the genera Aristostomias Zugmayer, 1913 , Astronesthes Richardson, 1845 , Bathophilus Giglioli, 1882 , Chauliodus Bloch & Schneider, 1801 , Echiostoma Lowe, 1843 , Eustomias Vaillant 1884 , Flagellostomias Parr, 1927 , Grammatostomias Goode & Bean, 1896 , Heterophotus Regan & Trewavas, 1929 , Idiacanthus Peters, 1877 , Leptostomias Gilbert, 1905 , Malacosteus Ayres, 1848 , Melanostomias Brauer, 1902 , Photonectes Günther, 1887 , Photostomias Collett, 1889 , Stomias Cuvier, 1816 , and Thysanactis Regan & Trewavas, 1930 (Gibbs, 1969; Parin, Novikova, 1974; Shcherbachev, Novikova, 1976; Gibbs et al., 1983; Gomon, Gibbs, 1985; Séret, Andreata, 1992; Haimovici et al., 1994; Parin, Borodulina, 1996, 1997, 2000; Parin et al., 1999; Clarke, 2000; Figueiredo et al., 2002; Menezes et al., 2003; Mincarone et al., 2004; Bernardes et al., 2005; Kenaley, Hartel, 2005; Bonecker, Castro, 2006; Braga et al., 2007; Haimovici et al., 2008; Costa, Mincarone, 2010; Lins Oliveira et al., 2015; Pinheiro et al., 2015; Mincarone et al., 2017; Eduardo et al., 2018a, 2020c; Judkins, Haedrich, 2018; Klautau et al., 2020; Melo et al., 2020; Tab. 2). Here we report on 10 new records of stomiid fishes in the Brazilian EEZ: Aristostomias grimaldii Zugmayer, 1913 , Astronesthes gudrunae Parin & Borodulina, 2002 , Bathophilus nigerrimus Giglioli, 1882 , Borostomias elucens (Brauer, 1906) , Eustomias bibulbosus Parr, 1927 , E. minimus Clarke, 1999 , Grammatostomias ovatus Prokofiev, 2014 , Melanostomias biseriatus Regan & Trewavas, 1930 , Pachystomias microdon (Günther, 1878) , and Photonectes achirus Regan & Trewavas, 1930 . Occurrences of Eustomias braueri Zugmayer, 1911 , E. schmidti Regan & Trewavas, 1930 , Grammatostomias dentatus Goode & Bean, 1896 , Leptostomias gladiator (Zugmayer, 1911) , Melanostomias bartonbeani Parr, 1927 and P. goodyeari Kenaley & Hartel, 2005 , are also confirmed for Brazilian waters. Records of Idiacanthus fasciola Peters, 1877 , Aristostomias polydactylus Regan & Tewavas, 1930 , Bathophilus altipinnis Beebe, 1933 , and Eustomias metamelas Gomon & Gibbs, 1985 in the Brazilian EEZ (UF 190899, MNRJ 30734, MCZ 132776, and MNRJ 30807, respectively) require verification, but those species likely occur in the region given their wide distribution in the Atlantic (Gomon, Gibbs, 1985; McEachran, Fechhelm, 1998; Stewart, Kenaley, 2015a; Kenaley, Stewart, 2015g).
