“…For instance, for decades the crested bigscale Poromitra crassiceps (Günther 1878) has been the only stephanoberyciform reported in Brazilian waters (Menezes et al ., ). A recent study, however, revealed that the diversity of this group in the area is much higher, with 13 species reported so far (Mincarone et al ., ). Even some circumglobal pelagic sharks were only recently reported off Brazil, such as the goblin shark Mitsukurina owstoni Jordan 1898 (Holanda & Asano Filho, ), the kitefin shark Dalatias licha (Bonnaterre 1788) (Soto & Mincarone, ) and the megamouth shark Megachasma pelagios Taylor, Compagno & Struhsaker 1983 (Amorim et al ., ).…”

“…Fishing surveys focused on the evaluation of biological parameters of fish stocks along the south‐western Atlantic shelf and slope have led to significant improvements in the knowledge of the diversity and biology of deep‐sea fishes. As result of these and similar initiatives, an impressive number of new distribution records has been provided and several new species were discovered in the past decade, covering a wide range of taxonomic groups, including Myxinidae (Mincarone, ; ), Scyliorhinidae (Soares et al ., ), Rajidae (Carvalho et al ., ), Anguilliformes (Melo, ; Melo et al ., ); Sternoptychidae (Lima et al ., ), Chiasmodontidae (Melo, ), Ophidiiformes (Franco et al ., ; Mincarone et al ., ; Nielsen, ; Nielsen et al ., ; Nielsen et al ., ), Stephanoberyciformes (Mincarone et al ., ), Gadiformes (Melo et al ., ), Ipnopidae (Franco et al ., ), Zoarcidae (Anderson & Mincarone, ; Mincarone & Anderson, ) and Bramidae (Carvalho‐Filho et al ., ).…”

The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South America evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes. The fresh waters of the continent are divided into 13 basin complexes, large basins consolidated as a single unit plus historically connected adjacent coastal drainages, and smaller coastal basins grouped together on the basis of biogeographic criteria. Species diversity, endemism, noteworthy groups and state of knowledge of each basin complex are described. Marine habitats around South America, both coastal and oceanic, are also described in terms of fish diversity, endemism and state of knowledge. Because of extensive land use changes, hydroelectric damming, water divergence for irrigation, urbanization, sedimentation and overfishing 4-10% of all fish species in South America face some degree of extinction risk, mainly due to habitat loss and degradation. These figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere. Conserving the remarkable aquatic habitats and fishes of South America is a growing challenge in face of the rapid anthropogenic changes of the 21st century, and deserves attention from conservationists and policy makers.

“…There is also an increase in the knowledge on the diversity of several Brazilian deep-sea fish groups in addition to the Ophidiiformes (e.g., Carvalho et al, 2005;Anderson & Mincarone, 2006;Mincarone & Anderson, 2008;Franco et al, 2009;Melo et al, 2009Melo et al, , 2010Lima et al, 2011;Mincarone et al, 2014 ). That situation results largely from the fact that only in the last decade collections made in recent fishing surveys performed offshore Brazil started to be properly studied.…”

2015

A new species of Barathronus (Ophidiiformes: Aphyonidae) is described from a single, mature male specimen (101 mm SL) bottom trawled on the continental slope of Rio Grande do Norte, northeastern Brazil, between 1,964 and 2,045 m depth. The new species is diagnosed among congeners by the following combination of characters: peritoneum transparent, deep-set eyes not visible, eight fangs on vomer, anal fin rays 69, predorsal length 42.0% SL, preanal length 49.5% SL, penis long, slender, and lacking a pair of lobes at its base, and presence of a ventral flexure of the anterior 2-3 vertebrae. Additionally, morphological data of three specimens of Barathronus bicolor collected in Brazilian waters are presented and compared with those from 51 specimens from the western Central Atlantic.Uma nova espécie de Barathronus (Ophidiiformes: Aphyonidae) é descrita a partir de um único exemplar macho (101 mm CP) coletado com arrasto de fundo no talude continental do Rio Grande do Norte, nordeste do Brasil, entre 1.964 e 2.045 m de profundidade. A espécie nova é diagnosticada entre as congêneres pela seguinte combinação de caracteres: peritônio transparente, olhos alojados profundamente e não distinguíveis, oito presas no vômer, nadadeira anal com 69 raios, comprimento pré-dorsal 42,0% CP, comprimento pré-anal 49,5% CP, pênis longo, afilado e sem um par de lobos em sua base, e presença de flexão ventral nas 2-3 vértebras anteriores. Adicionalmente, dados morfológicos dos três espécimes de Barathronus bicolor coletados em águas brasileiras são apresentados e comparados com aqueles de 51 espécimes do Atlântico Central ocidental.

In the Brazilian EEZ, ten species of the Melamphaidae were previously recorded: Melamphaes hubbsi, M. polylepis, M. typhlops, Poromitra crassiceps, P. megalops, Poromitra sp., Scopeloberyx opisthopterus, Scopeloberyx robustus, Scopelogadus beanii, and Scopelogadus mizolepis (Günther, 1887;Keene, 1987;Campos et al, 2008;Costa and Mincarone, 2010;Mincarone et al, 2014;Judkins and Haedrich, 2018).…”

Despite the increasing number of studies on the systematics of the Stephanoberycoidei (bigscales, pricklefishes, gibberfishes, hispidoberycids, and whalefishes) globally, knowledge about the diversity and distribution of the group in the western South Atlantic still remains fragmentary. In this study, we present new anatomical (meristic and morphometric) and distributional data for 18 species of the Stephanoberycoidei based on the examination of 150 specimens recently collected during the ABRACOS (Acoustics along the BRAzilian COaSt) expeditions off northeastern Brazil, including the Rocas Atoll, Fernando de Noronha Archipelago, and the seamounts off Rio Grande do Norte State, and additional museum specimens. In the Melamphaidae, remarks on the taxonomy of Melamphaes polylepis and of the Poromitra crassiceps and P. megalops species groups are made based on specimens examined. In addition, Scopeloberyx opercularis, currently considered as a junior synonym of Scopeloberyx robustus, is recognized as a valid species. Among the species identified, nine have their distributions extended in the western South Atlantic based on confirmed records: Melamphaes polylepis, M. typhlops, Poromitra megalops, Poromitra sp., Scopeloberyx opercularis, Scopeloberyx opisthopterus, Scopelogadus mizolepis, Cetostoma regani, and Rondeletia loricata. Eight further species are reported for the first time in Brazilian waters: Cetomimus sp. 1, Cetomimus sp. 2, Ditropichthys storeri, Gyrinomimus bruuni, Melamphaes eulepis, M. leprus, M. longivelis, and Melamphaes sp. Additional remarks on the taxonomy and distribution of the Stephanoberycoidei in the western South Atlantic are also provided.T HE Stephanoberycoidei comprises 23 genera and about 94 species of mostly meso-and bathypelagic teleosts commonly known as bigscales, pricklefishes, gibberfishes, hispidoberycids, and whalefishes (Nelson et al., 2016;Fricke et al., 2020a). Fishes of this suborder usually have a short to moderately long and somewhat compressed body, the subocular shelf and orbitosphenoid are absent, basibranchial tooth plates are also absent, with the exception of the copular tooth plate in the Cetomimidae, ossification is reduced to thin laminar bones on the surface of an extensively cartilaginous neurocranium, the supramaxillae are absent or reduced, and the extrascapular, when present, is greatly enlarged, partially or entirely covering the parietal bone (
