“…Curimatus altamazonicus of Cope (1878) was not Braga and Azpelicueta, 1983 Potamorhina pristigaster Semitapiscis laticeps Semitapiscis latior Semitapiscis squamoralevis * Semitapiscis planirostris Cope (1878:675) created the monotypic genus Potamorhina for Curimatus (Anodus) pristagaster Steindachner (1876:73). The remaining, thenknown Potamorhina species were retained by Cope in Curimatus, along with the majority of other curimatid species.…”

“…Eigenmann and Eigenmann (1889) subsequently united Charax planirostris Gray (1854) and the other species of the Potamorhina lineage described to that time (Potamorhina latior (Spix) and P. laticeps (Valenciennes) of this study) in the subgenus Semitapicis Eigenmann and Eigenmann ofCurimata. Semitapicis was thereafter utilized by different authors as either a genus or subgenus that included the majority of species that form Potamorhina of this study (e.g., Eigenmann and Eigenmann, 1889;Braga and Azpelicueta, 1983). A reevaluation of the situation (see "Comments on Semitapicis Eigenmann and Eigenmann") shows, however, that Semitapicis is actually properly associated phylogenetically with a different lineage of curimatids and is, therefore, unavailable for use with the species that constitute Potamorhina in this study.…”

“…Suprasinelepichthys Fernandez-Ye-pez (for Curimatus laticeps Valenciennes, with Curimatus altamazonicus Cope as a synonym), Gasterotomus Eigenmann (for Anodus latior Spix, incorrectly spelled Gasterostomus by Fernandez-Yepez), and Semitapicis (for Charax planirostris Gray) were components of another lineage of curimatids recognized by Fernandez-Yepez as the tribe Curimatini. The most recent treatment of the group (Braga and Azpelicueta, 1983) did not delve into the question of phylogenetic relationships between the species but did propose several shifts in taxonomy. Those authors retained Potamorhina as monotypic, synonymized Gasterotomus and Suprasinelepichthys into Semitapicis, which in their sense included all the other species in that study, and left Curimatus altamazonicus Cope in the synonymy of Curimatus laticeps Valenciennes (their Semitapiscis laticeps).…”

SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropo/ogy Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover.

“…They also represent an important regional food source with three Amazonian species dominating fish landings in different portions of the Amazon basin (Fernandes, 1997; Garcia, Tello, Vargas, & Duponchelle, 2009). The taxonomic revision associated with the morphology‐based phylogeny of Potamorhina (Vari, 1984) recognized five species: P. altamazonica (Cope, 1878) from the Amazon and Orinoco basins, P. laticeps (Valenciennes, 1849 from the Lago Maracaibo, P. latior (Spix & Agassiz, 1829) and P. pristigaster (Steindachner, 1876), both from the Amazon basin, and P. squamoralevis (Braga & Azpelicueta, 1983) from the Rio Paraguay and lower Rio Paraná. That study also provided the first hypothesis of interspecific relationships (Figure 1) mostly based on osteology, morphology of the gasbladder, squamation, and pigmentation (Vari, 1984).…”

Potamorhina includes the largest species in the Neotropical fish family Curimatidae. They perform long‐distance migrations in large schools and represent relative importance for regional fisheries in South American lowlands. A morphology‐based phylogenetic study recognized five species and proposed interspecific phylogenetic relationships mostly based on osteology, squamation, and morphology of the gasbladder. Subsequent cytogenetic studies revealed extreme variability in diploid numbers and other cytomolecular structures and hypothesized multiple events of chromosome rearrangements with centric fissions followed by reversed fusions. However, neither the taxonomic revision and phylogeny nor the cytogenetic hypothesis of chromosome evolution in Potamorhina was tested using molecular phylogenetic approaches. Here, we use mitochondrial and nuclear DNA sequences to delimit species of Potamorhina with an extensive sampling across the Amazon basin and use phylogenetic methods to test prior hypothesis of multiple events of chromosome rearrangements during the evolution of the genus. Phylogenetic and species delimitation methods clearly support the presence of five species but reveal novel interspecific relationships allowing a reinterpretation of the morphological characters relative to the number of vertebrae, caudal peduncle pigmentation, and modifications in the gasbladder chambers. With the new phylogenetic arrangement, we propose a novel hypothesis of occurrence of a single chromosome fission in the lineage of P. latior followed by an extraordinary event that involved more than 20 chromosome‐pair fissions during the evolution of the ancestor of P. altamazonica and P. squamoralevis. This novel hypothesis represents a simpler and more conceivable explanation for the achievement of these elevated chromosome numbers during the evolution of Potamorhina.
