The first fossil from the superdiverse clade Loricariinae (Siluriformes, Loricariidae): a new species of the Armored Catfish from the late Miocene of Paraná, Argentina
TLDR
A new species of Loricariinae belonging to the genus Sturisomatichthys from late Miocene Ituzaingó beds at Paraná locality, Entre Ríos province, Argentina is described, indicating that the Miocene fish faunas from paleo-Paraná basin were close to those of northern South America.

ABSTRACT The fossil record of ‘phractocephaline' catfishes in South America is relatively rich. The extinct species Phractocephalus ivy Azpelicueta and Cione, 2016, was named on the basis of diverse
Brachyplatystoma promagdalena, new species, a fossil goliath catfish (Siluriformes: Pimelodidae) from the Miocene of Colombia,
TLDR
The Miocene species of Brachyplatystoma signals the former large river and biotic connection between the paleo-Amazonas-Orinoco system and central Colombia, and other fossils of aquatic vertebrates from the La Venta fauna show this same biogeographic relationship.
Brachyplatystoma capapretum: a New Species of Goliath Catfish from the Amazon Basin, with a Reclassification of Allied Catfishes (Siluriformes: Pimelodidae)
TLDR
The systematic position of the new species was investigated with a maximum parsimony phylogenetic analysis of morphological characters and the resulting cladograms identify a nested set of unambiguous characters supporting the following monophyletic groups and taxonomic recommendations.
Check list of the freshwater fishes of South and Central America
TLDR
The syntype series is presumed to consist of the specimens listed as holotype and paratypes in Garavello and Santos (1992) as well as Oyakawa (1996).
Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene - a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)
TLDR
The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Rios, Argentina, is reevaluated and analysis indicates that the specimen is rather a fish of the genus Leporinus, family Anostomidae (Characiformes).
Phylogenetics of the South American Catfish Family Pimelodidae (Teleostei: Siluriformes) using Nuclear and Mitochondrial Gene Sequences
TLDR
Results of Bayesian likelihood and maximum parsimony analyses of the combined sequence data consistently recover 40 monophyletic pimelodid clades above the species level, and the molecular data do not support monophyly of the genus Brachyplatystoma.
Megapiranha paranensis, a New Genus and Species of Serrasalmidae (Characiformes, Teleostei) from the Upper Miocene of Argentina
TLDR
The pattern of tooth placement exhibited by the fossil Megapiranha is intermediate between the double-row condition of pacus and the single-rows condition of piranhas, and suggests how the double row of teeth may have been rearranged into a single row in the evolution of pirans.
Taxonomic revision of the deep channel electric fish genus Sternarchella (Teleostei: Gymnotiformes: Apteronotidae), with descriptions of two new species
TLDR
A maximum parsimony analysis of 76 morphological characters from seven ingroup and seven outgroup taxa recovered a non-monophyletic Sternarchella, in which a clade comprising two species with a ventral mouth is the sister group to aClade comprising seven species that possess a terminal or superior mouth.
Goliath catfish spawning in the far western Amazon confirmed by the distribution of mature adults, drifting larvae and migrating juveniles
TLDR
These results provide an empirical baseline for tagging experiments, life histories extrapolated from otolith microchemistry interpretations and other methods to establish goliath catfish migratory routes, their seasonal timing and possible return (homing) to western headwater tributaries where they were born.
