Brachychalcinus reisi, a new species of characid fish, is described from the rio Curuá, tributary Iriri, Xingu basin, Serra do Cachimbo, Pará State, Brazil. The can be distinguished its congeners by presence series longitudinal black wavy stripes on entire body and lower number scale rows between dorsal-fin origin lateral line (7–8 vs. 8–12). Additionally, differs B. copei, parnaibae, retrospina branched rays (9 vs.10). This first description subfamily since revisionary study...
Abstract Is there only one electric eel species? For two and a half centuries since its description by Linnaeus, Electrophorus electricus has captivated humankind capacity to generate strong discharges. Despite the importance of in multiple fields science, possibility additional species-level diversity genus, which could also reveal hidden variety substances bioelectrogenic functions, hitherto not been explored. Here, based on overwhelming patterns genetic, morphological, ecological data, we...
Abstract The Amazon Basin is an unquestionable biodiversity hotspot, containing the highest freshwater on earth and facing off a recent increase in anthropogenic threats. current knowledge spatial distribution of fish species greatly deficient this basin, preventing comprehensive understanding hyper-diverse ecosystem as whole. Filling gap was priority transnational collaborative project, i.e . AmazonFish project - https://www.amazon-fish.com/ Relying outputs we provide most complete records...
A new species of Corydoras is described from the upper Rio Machado, Madeira basin, Rondônia State, Brazil. The can be distinguished its congeners by absence contact between posterior process parieto-supraoccipital and nuchal plate; a ventral laminar expansion infraorbital 1 conspicuously developed; margin pectoral-fin spine with serrations along almost entire length, only lacking in distal portion. Additionally, hephaestus possesses dorsal pectoral spines short, exhibits an unusual color...
A new species of Hyphessobrycon is described from the rio Aripuanã, Madeira basin, Amazonas State, Brazil. procyon can be distinguished its congeners by unique combination following features: elongation dorsal fin in mature males, absence dark blotches on fin, and presence two humeral blotches. The possibility a relationship within H. elachys, heliacus, loweae, moniliger, peugeoti discussed based sharing characteristics related to sexual dimorphism tooth morphology.
A new species of Microschemobrycon with a restricted distribution was recently discovered in the Rio Curuá, Xingu basin, Pará, Brazil. cryptogrammus can be promptly distinguished from all congeners by presence rounded, dark, conspicuous caudal-peduncle blotch and subjacent dark midlateral stripe visible life. Additionally, its congeners, except M. elongatus, longitudinal along lower jaw. The elongatus presenting lateral line 36–38 pored scales, anterior posterior nostrils coalescend,...
Sorubim trigonocephalus was described in 1920 by Alípio de Miranda Ribeiro, based on a single specimen collected locality identified as “Porto Velho”, during the "Comissão das Linhas Telegráficas Estratégicas Mato Grosso ao Amazonas” (more commonly known Rondon Commission). Given that type is Porto Velho, species has been referred to Madeira River basin (Lundberg & Littmann, 2003; 2007; Eschmeyer et al., 2016). Nevertheless, after its description, no additional specimens were despite...
This study represents an inventory of fish collected in six small tributaries from the rio Tarumã river, Jaru Biological Reserve, middle Machado, Vale do Anari town, Rondônia, Brazil. The fieldwork was carried August 2019 and 2021 streams up to third order during low water period, a 50 m blocked stretch located 1 km upstream mouth river. sampling effort each stream standardized with five people collecting hand-nets seine-nets for 2 hours. A total 2.989 individuals, 64 species, 55 genera, 22...
Identifying the main taxonomic, phylogenetic and trait dimensions of beta diversity, evaluating their prospective drivers, advances our understanding patterns processes involved in evolution biological assemblages. Using comprehensive databases on distribution, phylogeny, morphological traits (later referred as functional traits) Amazonian freshwater fishes, we analyzed diversity these three to evaluate historical contemporary drivers. We mostly focused pure turnover components (Taxoβsim,...
Abstract A crowdfunding initiative carried out by aquarists allowed us to sample tributaries of the rio Tapajós basin in surroundings Jacareacanga and Maués towns, Pará Amazonas states, respectively, Brazilian Amazon. During this expedition, 13 Corydoradinae species were captured, from which at least five could be confirmed as new science. In article, we formally describe two these species. Both can distinguished their congeners having following features: (I) ventral surface trunk with small...
