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 Hemigrammus is described from the upper Rio Negro, Amazon basin, Brazil. The distinguished all congeners by its unique color pattern consisting a single humeral blotch clearly spaced conspicuous midlateral dark stripe, which extends fifth or sixth anteriormost vertical scale row to basis middle caudal-fin rays. Comments on putative relationships are provided.
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...
Abstract A new species of Moenkhausia from the rio Culuene, Xingu basin, in Mato Grosso State is described here through genetic and morphological data. This differs all congeners by following combination characters: presence reddish color on posterior portion body, as well base anal, adipose, pelvic fins live specimens; a conspicuous midlateral dark stripe, which extends margin opercle to middle caudal-fin rays, becoming wider more vertical dorsal-fin origin; absence humeral blotch; blotches...
Abstract Pimelodidae is a family of large‐sized catfishes consisting 116 valid species divided into 30 genera distributed in the Neotropical region. Despite recent advancements understanding pimelodid phylogeny, several internal relationships have remained unclear and received limited support from various phylogenetic analyses. We provide new genomic dataset comprising 55 representing 25 related siluriform families Aspredinidae, Auchenipteridae, Cetopsidae, Doradidae, Diplomystidae,...
The Neotropical family Heptapteridae comprises 228 valid species widely distributed in South America. Imparfinis is one of the most diverse genera this family, with 25 distributed, inhabiting streams from Costa Rica to Argentina. Old descriptions coupled lack recent systematic studies Upper Paraná river basin have led a taxonomic impediment and hindered advancement other areas, such as ecology, cytogenetic, phylogenetic, evolution. We conducted first integrative study analyzing both...
Os carnívoros são importantes componentes ecológicos dos ecossistemas, pois controlam a abundância, distribuição e diversidade das populações de suas presas. Desta forma, considerados como espécies-chaves na manutenção restauração da resiliência ecossistemas. Nesse grupo, onça-parda (Puma concolor) é espécie mamífero silvestre mais amplamente distribuída do hemisfério ocidental, porém, exigências em tamanho área vida alimentação mostram-se um fator restrição para sobrevivência por fatores...
The species Moenkhausia australis was described based on two specimens from arroyos Trementina and Chagalalina, Rio Paraguai basin, Paraguay. Its taxonomic history is complex for many years the considered a synonym of sanctaefilomenae. shares reticulated color pattern with oligolepis/M. sanctaefilomenae complex, being more similar within included in to M. oligolepis, sanctaefilomenae, forestii, which it prepelvic region laterally compressed, feature also observed Bario steindachneri....
The ribeirão Sucuri, a tributary of the rio Tietê, and part upper Paraná basin, is located in municipality of Pongaí, São Paulo state. ichthyofauna Sucuri was sampled at nine collection sites May 2018. Our study captured 408 specimens representing five orders, 11 families, 35 species. Among species collected, two have not been previously reported from Tietê basin: Eigenmannia guairaca Peixoto, Dutra...
Abstract In this study, a new species of Moenkhausia is described from the upper rio Juruena, Tapajós basin, Brazil. It distinguished all congeners by presence minute bony hooks in fins both mature females and males combination prepelvic region flattened, dorsal portion humeral blotch extending two scales horizontally vertically, lateral line with 28–32 scales, five scale series above below line; circumpeduncular 13–14, anal‐fin rays 16–19 eyes blue live specimens. The also supported high...
Hyphessobrycon ocoae (Fowler, 1943) (n. comb., n. stat.) se revalida aquí y considera un sinónimo senior de otrynus Benine & Lopes (2008). también ha identificado erróneamente como Hemigrammus marginatus en la literatura más antigua. Revisamos las características diagnósticas especie, que incluyen una ancha área pigmentación oscura cada lóbulo aleta caudal unido verticalmente por pigmento oscuro mitad distal los radios membranas (vs. áreas oscuras subdistales lóbulos separados Hy. bayleyi...
