The is distinguished its congeners by the presence conspicuous dark spots all over body. Moreover, can be diagnosed absence moderate keels along each lateral series plates, developed adipose fin, enlarged, fleshy folds between dentaries, dorsal-fin spinelet larger than spine, lacking enlarged odontodes margins snout and ridges before eyes,...
Two new species of Lithoxus, a genus diagnosed by possessing dorsoventrally depressed body, large round oral disk, and small tooth cusps with few teeth, are described from two drainages the Guiana Shield: Lithoxus jariensis rio Jari basin L. raso Raso, Amapá basin. The species, jariensis, is distinguished congeners having an adipose fin, number branched anal-fin caudal-fin rays, color pattern adipose-fin length, dorsal adipose-caudal distance, caudal peduncle depth, cleithral width,...
In the present study, we describe a new species of Neoplecostomus from central Brazil. The is known Córrego Cachoeira right tributary upper Rio Paraná basin. It can be distinguished all congeners by absence adipose fin or azygous plates on dorsum surface caudal peduncle. Additionally, differs N. botucatu and paranensis having dark with unique v-shaped hyaline vertical area larger lower lip. A discussion morphological variation among also provided.
A new species of Hisonotus from rio Juma, located at the right margin lower Aripuanã, Madeira basin is described. The distinguished its congeners mainly by a reddish-tipped premaxillary and dentary teeth, V-shaped spinelet, three lateral plates in abdominal series, coloration pattern caudal fin with transversal dark bars, morphometric characters.
A new species of Parotocinclus is described from the Rio Tocantins basin, State, Brazil. The distinguished congeners by a combination characters such as: (1) unique pattern body coloration with five transverse dark bars; (2) absence an adipose fin or small platelet at typical adipose-fin region; (3) conspicuous dots broadly distributed on body; (4) triangular blotch anterior base dorsal fin; and (5) presence V-shaped spinelet.
Abstract The Neotropics harbor the most species-rich freshwater fish fauna on planet, but timing of that exceptional diversification remains unclear. Did accumulate species steadily throughout their long history, or attain remarkable diversity recently? Biologists have debated relative support for these museum and cradle hypotheses, few phylogenies megadiverse tropical clades included sufficient taxa to distinguish between them. We used 1288 ultraconserved element loci spanning 293 species,...
Abstract Neotropical tetras of the family Characidae form largest and most taxonomically complex clade within order Characiformes. Previous phylogenetic relationships concur on recognition four major subclades, whereas knowledge intergeneric interspecific remains largely incomplete or nonexistent. We sampled 575 specimens 494 species 123 genera classified in Characidae, generated new molecular data ultraconserved elements (UCEs), used likelihood Bayesian analyses. The phylogeny (1348 UCE...
Gymnotocinclus canoeiro n. sp. of the Hypoptopomatinae is described from small tributaries upper rio Tocantins basin. It distinguished G. anosteos by having five characters: (1) presence body dermal plates, (2) pectoral girdle not exposed in ventral view, (3) pelvic spine longer than males, (4) fin with seven to eight branched rays, and (5) an adipose fin. Furthermore, maximum likelihood (ML) analysis was used estimate a molecular phylogeny previously published data one nuclear (F-Reticulon...
A new species of Hisonotus is described from headwaters rio Araguaia basin, municipality Barra do Garças, Mato Grosso state, Brazil. The distinguished its congeners by a V-shaped spinelet, yellowish teeth, absence unpaired platelets at typical adipose fin position, the caudal-fin color hyaline with three transverse dark bars, one abdominal median plate series, and morphometric meristic characters.
Abstract The family Trichomycteridae is one of the most diverse groups freshwater catfishes in South and Central America with eight subfamilies, 41 genera more than 300 valid species. Its members are widely distributed throughout America, reaching Costa Rica recognized by extraordinary anatomical specializations trophic diversity. In order to assess phylogenetic relationships Trichomycteridae, we collected sequence data from ultraconserved elements (UCEs) genome 141 specimens 12 outgroup We...
The genus Rineloricaria is a Neotropical freshwater fish group with long and problematic taxonomic history, attributed to the large number of species pronounced similarity among them. In present work, information different molecular approaches were used identify boundaries characterize independent evolutionary units. We analyzed 228 samples assembled in 53 distinct morphospecies. A general mixed yule-coalescent (GMYC) analysis indicated existence 70 entities, while BOLD system analyses...
Abstract Aim To investigate the effects of river capture on biogeographical history South American freshwater fishes. Location Western Amazon and La Plata basins, adjacent drainages. Methods We used a species‐dense time‐calibrated phylogeny long‐whiskered catfishes (Siluriformes, Pimelodidae) to calculate likelihoods for 16 scenarios capture, each differing in details (1) landscape evolution and/or (2) models species range evolution. designed eight alternative ( LEM s) represent distinct...
Ecological opportunity is often proposed as a driver of accelerated diversification, but evidence has been largely derived from either contemporary island radiations or the fossil record. Here, we investigate potential influence ecological on transcontinental radiation South American freshwater fishes. We generate species-dense, time-calibrated molecular phylogeny for suckermouth armored catfish subfamily Hypostominae, with focus species-rich and geographically widespread genus Hypostomus....
Abstract The family Callichthyidae, which comprises the subfamilies Corydoradinae and Callichthyinae, represents one of largest families within Siluriformes. Corydoradinae, subfamily alone accounts for >200 valid species, with new species being described frequently. This holds significant popularity among catfish enthusiasts worldwide, mainly because Corydoras are small, peaceful, colourful fishes. Recognizing existence polyphyletic groups aim this study was to construct a...
