Introduction
I am a taxonomist, phylogeneticist, and evolutionary biologist interested mostly in understanding the general patterns of diversification and evolutionary history of recent groups of freshwater fishes and to describe its biodiversity. Currently, I am a postdoc at the Institute of Ecology and Evolution in association with Wyss Academy for Nature at University of Bern working in a large-scale project of mitigating climate change impacts on freshwater fish diversity in Switzerland.

Article
Full-text available
Microlepidogaster longicolla, new species, is described from the rio São João of the upper rio Paraná basin near Brasília, in central Brazil. The new species differs from M. perforatus, the only other species in this genus, by having a continuous lateral line, median lateral plate series reaching, rather than falling short of, the end of the caudal...
Article
Full-text available
A new species of the rubbernose pleco genus Chaetostoma is described from the Maicuru and Seiko Rivers, a northern tributary of the lower Amazon River and a tributary of the lower Xingu River, respectively, both in Par State, Brazil. The new species is diagnosed from all congeners, except members of the Chaetostoma anale species group, by having an...
Article
The Neotropics harbour the greatest diversity of freshwater fish on Earth. Despite recent advances in characterizing the fish fauna, the total number of species, distri-butional range, evolution and ecological traits remain uncertain. Thus, we quantify shortfalls in the knowledge of taxonomy (Linnean shortfall), geographic distribution (Wallacean s...
Article
Full-text available
Through the DNA barcoding technique using the cytochrome oxidase subunit I (coI) mitochondrial gene, a high degree of fraudulent commerce of Cod (Bacalhau in Portuguese) was detected in the city of Porto Alegre, Brazil. Tested products included frozen and dried salted fish during the Easter period, the season with the highest Cod consumption. The s...

A recent study based on genomic data by Roxo et al. (2019) provided a phylogeny of the Loricariidae, the largest catfish family and second largest Neotropical fish family with approximately 1,000 species. The study represents a valuable and innovative contribution for understanding higher-level relationships within the family. The phylogenetic tree...
Article
A comprehensive phylogeny of species relationships of the Auchenipteridae is reconstructed here with a large-scale taxon sampling based on combined morphological and molecular datasets. The hypothesized phylogeny includes most species of Auchenipteridae (97 of 124 valid species) and multiple members of siluriform families as an outgroup (32 species...

Article
Full-text available
A new species of Curculionichthys is described from the rio Curuá-Una basin, in the northern edge of the Brazilian Shield, State of Pará, Brazil. The new species is diagnosed from congeners by possessing a single rostral plate, by having darkened tooth-crowns, and by a series of morphometric and meristic data. A close examination of the species of...
Article
Fraudulent mislabeling of fish products has been reported with some frequency, representing an important problem in the food industry and regulatory agencies of many countries. This case reports a fraudulent substitution of shark fillets for the much cheaper Striped-catfish, in a large purchase for public elementary school meals in a Brazilian town...
Article
Curculionichthys scaius, new species, is distinguished from other congeners by having two usually conspicuous, somewhat triangular dark brown speckles lateral to the anal-fin origin, a pointed snout with paired rostral plates, numerous lateral abdominal plates, a single series of large median abdominal plates, numerous dentary and premaxillary teet...
Article
Full-text available
Spinipterus Akama & Ferraris, 2011 is a monotypic genus known only by the holotype of its single species S. acsi , described from a creek tributary to the Nanay River, in the Peruvian portion of the Amazon basin. A second specimen of this genus and species representing the first record of occurrence in Brazil is reported from the Juruá River, upper...

Tutorial for composing distribution maps - Part II: Hypsometric maps. Portuguese version: Pages 14 - 32 English version: Pages 32 - 34
Article
Otothyropsis dialeukos is described from Itá creek, tributary to the upper Río Paraná basin, Paraguay. The new species is distinguished from its congeners by having a unique caudal-fin coloration pattern composed of a brown to almost black background with roundish hyaline blotches in the middle of the outermost branched rays and a hyaline posterior...

Resumo: Glanidium inclui sete espécies, de porte médio a grande (90­130 mm de Comprimento Padrão). Seis são endêmicas das drenagens costeiras do sul e sudeste do Brasil, entre o rio São Francisco (MG) e a Lagoa dos Patos (RS), contando com uma espécie restrita as drenagens costeiras no escudo das Guianas, entre o Suriname e o Amapá, Brasil. O padrã...
Article
A new species of Gelanoglanis is described based on specimens collected in the Tocantins River, a tributary of the Amazon Basin. The new species is distinguished from congeners by unusual features to the genus such as the pelvic fin falling short of the urogenital opening by a distance larger than the anal-fin length, the first unbranched dorsal an...
Article
Full-text available
Analysis of specimens of the auchenipterid catfish genus Tatia collected in the rio Teles Pires, a tributary of the rio Tapajós, along the border between the states of Pará and Mato Grosso, Brazil, revealed it to be an undescribed species. This new species is distinguished from all congeners with the exception of T. carolae and T. musaica by the in...
Article
Full-text available
Previously proposed synapomorphies for the genus Gelanoglanis of the catfish family Auchenipteridae are evaluated and four additional features involving the relationship between the mesethmoid and premaxilla, the very fleshy anterior portion of the snout, the lack of ossification of the second through fourth infraorbitals, and the incomplete poring...
Article
Full-text available
Microlepidogaster discontenta, new species, is described from a creek tributary to the upper rio São Francisco basin, central Brazil, and constitutes the first record of the genus in that basin. It is distinguished from all congeners mainly by the odontodes on the caudal peduncle being conspicuously arranged in longitudinal lines (vs. odontodes on...
Article

Otothyropsis alicula is described from the Rio Santo Antônio, Rio Grande basin, upper Rio Paraná drainage, Brazil. The new species is distinguished from its congeners by having a unique color pattern in the caudal fin, rectangular dorsal-fin spinelet, short pectoral-fin spine and first pelvic-fin ray, suture between contiguous bifid neural spines t...

Otothyropsis polyodon, sp. n., and O. biamnicus, sp. n., two new species of loricariid catfishes are described from the rio Paraná basin. Otothyropsis biamnicus and O. polyodon differ from two other Otothyropsis by having a longer caudal peduncle, middle series of lateral plates complete and with higher number of plates, and the anterior margin of...

Microlepidogaster arachas Martins, Calegari & Langeani, sp. nov., a new Hypoptopomatinae, is described from the upper rio Paraná basin. The new species is distinguished from M. longicolla and M. dimorpha by having the anterior portion of the compound supraneural plus first dorsal-fin proximal radial contacting the neural spine of the ninth vertebra...

Otothyropsis piribebuy, new species, is described from the río Piribebuy, a tributary to the río Paraguay basin, Cordillera, Paraguay. The new species is distinguished from O. marapoama mainly by having a continuous mid-dorsal series of 17-18 lateral plates, a robust levator crest in the hyomandibula, naked areas in the abdomen, an unpigmented circ...

Project
The goal of our project is to inform the conservation of Switzerlands rivers and lake biodiversity using species distribution models combined with a systematic conservation planning approach. We aim to document the taxonomic diversity of fishes in Switzerland, better understand the environmental determinants of freshwater fish ranges, quantify the causes of historic distribution and diversity loss, and identify priority areas for future restoration actions of freshwaters in Switzerland. We have a particular focus on the future role of climate change affecting these conservation plans.
