A recent field inventory focusing on catfishes of the trichomycterine genus Cambeva detected occurrence two morphotypes, C. barbosae and cubataonis, in Guaratuba-Babitonga-Itapocu area (GBIA) southern Brazil, reporting some discordance with results coalescent-based approaches for species delimitation that indicated different estimates number. Contrastingly, based examination characters taken from external morphology osteology, we here recognised six GBIA: cf. botuvera, a polymorphic...
Cambeva melanoptera sp. nov. is described from stream tributaries of the Rio Iratim, Iguaçu drainage, southern Brazil. This new species remarkable with a colour pattern not found elsewhere among trichomycterid catfishes, consisting broad distal black zone in all unpaired and pectoral fins, strongly contrasting pale-yellow proximal zone. C. also differs other trichomycterids eastern South America by presence nasal barbel about thrice longer than maxillary rictal barbels. Due to similar...
Abstract The complete mitogenome of four Scleromystax barbatus populations distributed along the species natural range was reconstructed, comprising first study with this genus and second Corydoradinae specimens sampled from their environment deposited in permanent collections. S. is a circular molecule 16,694 base pairs (bp) 37 genes, 22 which are tRNA, two rRNA, 13 protein-coding genes one control region (D-loop). An 18-nucleotide insertion sequence found between ATPase subunit 6 COIII...
Abstract This study assessed the lapillus otolith shapes of males and females Scleromystax barbatus from southern southeastern regions in Atlantic Rainforest biome employing Fourier Wavelet descriptors. The utricular otoliths S. are ovoid, with gibbus maculae occupying almost all ventral portion, similar to most Callichthyidae species. Otoliths studied region more elongated anterior-posterior direction present larger sulcus maculae, heterogeneous borders. We found no sexual-based dimorphism...
Abstract: Aim To investigate reproductive characteristics in a small population of Psalidodon aff. fasciatus living isolation an environment with unique geological configuration, doline-shaped depression (known as Furna 2), mean diameter 80 m and water depth 50 m, natural heritage the Vila Velha State Park (VVSP). Methods The fish were collected between February 2019 January 2020 using nets pots; standard length total weight measured. gonads also removed for histological analysis. Estimates...
O presente estudo investigou os peixes de riachos em seis áreas com interesse para a proteção ambiental do município Joinville (SC). As estações coleta são formadas por pequenos da Bacia Hidrográfica Rio Cachoeira. A composição espécies foi avaliada compreender padrões distribuição espacial e o endemismo regional. Os resultados dos levantamentos campo nas 18 registraram 22 pertencentes nove famílias ordens. Characidae família maior riqueza, seguida Poeciliidae Callichthyidae. mais...

Aspidoras fuscoguttatus Nijssen & Isbrücker, 1976 is a small, relatively common armored catfish considered endemic to the upper Paraná river basin. Here, based on recent collections, as well morphological and molecular evidence, known geographic distribution of this species extended basin São Francisco River. Specimens were collected during biological surveys in two unnamed tributaries Paraopeba River, headwaters The new records may be consequence headwater...
The natural distribution of the aplocheiloid killifish Cynopoecilus fulgens Costa 2002 is expanded here with specimens collected in Mampituba River basin Santa Catarina State, Brazil. This record expands its geographical within Atlantic Forest coastal drainages southern
