Villarins, Bárbara T., Dario, Fabio Di, Eduardo, Leandro N., Lucena-Frédou, Flávia, Bertrand, Arnaud, Prokofiev, Artem M. & Mincarone, Michael M., 2022, Deep-sea dragonfishes (Teleostei: Stomiiformes) collected from off northeastern Brazil, with a review of the species reported from the Brazilian Exclusive Economic Zone, Neotropical Ichthyology (e 220004) 20 (2), pp. 1-78 : 10-11

GONOSTOMATIDAE

The Gonostomatidae includes 24 valid species in the genera Cyclothone Goode &

Bean, 1883, Gonostoma Rafinesque, 1810 , Margrethia Jespersen & Tåning, 1919 , Sigmops

Gill, 1883, and Zaphotias Goode & Bean, 1898 , with a wide distribution in the Atlantic, Indian, Pacific, and Southern oceans (Gon, 1990a; Duhamel et al., 2014; Nelson et al., 2016; Koeda, Ho, 2019; Fricke et al., 2022). Fishes of the family are characterized by having an elongate and laterally compressed body, at least one row of serial photophores, chin barbel and postorbital photophore absent, adipose fins present or absent, 16–67 anal-fin rays, and 12–16 branchiostegal rays (Harold, 1998, 2003; Kenaley, Stewart, 2015c; Nelson et al., 2016). Gonostomatids also have the dorsal-fin origin near the middle of body or slightly posterior to it, one row of premaxillary teeth, and two rows of dentary teeth near the symphysis (Harold, 1998, 2003).

Fourteen species in all the five currently recognized genera of the Gonostomatidae were previously reported in Brazilian waters (Mukhacheva, 1972, 1974, 1978; Séret, Andreata, 1992; Figueiredo et al., 2002; Menezes et al., 2003; Bernardes et al., 2005; Braga et al., 2007; Haimovici et al., 2008; Costa, Mincarone, 2010; Bonecker et al., 2014; Pinheiro et al., 2015; Stocco, Joyeux, 2015; Mincarone et al., 2017; Olivar et al., 2017; Eduardo et al., 2018a, 2020c; Judkins, Haedrich, 2018; Melo et al., 2020; Pinheiro et al., 2020; Tab. 2). Cyclothone signata Garman, 1899 was included in a list of Brazilian marine deep-sea fishes by Melo et al. (2020), likely based on NHMUK 1969.6.26.254-257 (four specimens collected near the Fernando de Noronha Archipelago). However, records of the species in the Atlantic require verification, since they actually may refer to C. alba Brauer, 1906 (Carneiro et al., 2019). Here we also report for the first time on the occurrence of Gonostoma denudatum Rafinesque, 1810 in the Brazilian EEZ.
