Characidium heirmostigmata, a new characidiin fish (Characiformes: Crenuchidae) from the upper rio Paraná basin, Brazil

Neotropical Ichthyology
Characidium heirmostigmata new species is described from the rio Ivaí drainage, upper rio Paraná basin, Paraná State, Brazil. The new species is diagnosed among its congeners by the possession of eight to 11 incomplete oblique dark bars on the body sides,

Seasonal dynamics of fish diversity and assemblage composition in temporary pools of a protected Atlantic Forest area

Journal of Fish Biology, EarlyView.
Abstract The Atlantic Forest is one of the top five biodiversity hotspots on the planet and is considered a global priority for conservation, largely due to extensive human‐driven deforestation. Temporary pools in the Atlantic Forest harbour unique and vulnerable fish assemblages, yet remain poorly studied, particularly within protected areas.

Interspecific chromosomal divergences in the genus Characidium (Teleostei: Characiformes: Crenuchidae)

Neotropical Ichthyology
Karyotypes of seven fish species of the genus Characidium, three of them studied for the first time, were characterized using conventional cytogenetic techniques (Giemsa staining, Ag-NOR, and C-banding).

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

Journal of Fish Biology, Volume 109, Issue 3, Page 1737-1746, September 2026.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

Characidium serrano Buckup & Reis, 1997 (Characiformes, Crenuchidae): insights into phylogenetic relationships, and comments on distribution

Acta Zoológica Lilloana
Characidium is the most diverse genus within the family Crenuchidae, with a total of 88 valid species, although there is evidence that it is probably a polyphyletic group.

Dinâmica populacional de Characidium lauroi e C. alipioi (Teleostei, Crenuchidae) na microbacia do Ribeirão Grande, serra da Mantiqueira Oriental, Estado de São Paulo - DOI: 10.4025/actascibiolsci.v29i3.481

Acta Scientiarum: Biological Sciences, 2007
Em riachos de pequena ordem, o alto e variável fluxo de água oferece tanto vantagens como desvantagens para o ciclo de vida de peixes. Mesmo espécies próximas que vivem em habitats semelhantes podem apresentar diferentes em seus padrões de ciclo de vida.
