Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes)
A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The
Morphology of the Gas Bladder in Thorny Catfishes (Siluriformes: Doradidae)
ABSTRACT. The gross morphology of the gas bladder is described, illustrated, compared and categorized among 86 of 88 nominal valid and six undescribed species representing all 31 genera of Doradidae
Ossancora, New Genus of Thorny Catfish (Teleostei: Siluriformes: Doradidae) with Description of One New Species
ABSTRACT. Ossancora, new genus, is diagnosed within Doradidae by having the unique combination of posterior coracoid process approximately as long as posterior cleithral process in adults, posterior
Comparative morphology of the gas bladder in driftwood catfishes (Siluriformes: Auchenipteridae)
TLDR
Eight phylogenetic characters are proposed based on the morphology of the gas bladder and associated structures in species of Auchenipteridae, and the evolution of those characters in the family discussed.
First report of B chromosomes in three neotropical thorny catfishes (Siluriformes, Doradidae)
TLDR
The chromosomal characteristics of Platydoras armatulus, Pterodoras granulosus and Ossancora punctata were investigated through classical cytogenetics approaches and the diploid number observed in Ossanca punctata is an evidence of centric fusions and up to the moment it is the highest diploids number reported for Doradidae.
A new species of Leporinus Agassiz, 1829 from the upper Rio Paraná basin (Characiformes, Anostomidae) with redescription of L. elongatus Valenciennes, 1850 and L. obtusidens (Valenciennes, 1837)
TLDR
A new species of Leporinus, endemic to the upper Rio Parana, very similar and sometimes mistaken with L. obtusidens, is formally described.
Fishes from the Itapecuru River basin, state of Maranhão, northeast Brazil.
TLDR
During several expeditions to the Itapecuru basin, 69 fish species belonging to 65 genera, 29 families and 10 orders were collected and Characiformes and Siluriformes were the orders with the largest number of species.
Palaeontological Evidence for the Last Temporal Occurrence of the Ancient Western Amazonian River Outflow into the Caribbean
TLDR
The Pliocene Castilletes and San Gregorio formations potentially represent the last lithostratigraphic units related with an ancient western Amazonian fish fauna and that drainage system in the Caribbean.
Morphology of the gas bladder in bumblebee catfishes (Siluriformes, Pseudopimelodidae)
TLDR
Five phylogenetic characters are proposed based on the morphology of the gas bladder and associated structures in species of Pseudopimelodidae, and the evolution of those characters in the family is discussed.
