A new miniature characid (Ostariophysi: Characiformes: Characidae), with phylogenetic position inferred from morphological and molecular data. [PDF]
PLoS ONE, 2013 Erythrocharax altipinnis is described from the Serra do Cachimbo, Pará, Brazil. The new taxon is distinguished from all of the Characidae genera by having the pelvic bones firmly attached through the isquiatic processes; a nearly triangular hiatus in the

Karyotypic diversity in a population of Bryconamericus aff. iheringii (Characidae)
Genetics and Molecular Research, 2014 Bryconamericus comprises 56 species distributed into three groups, on the basis of the position and shape of the maxillary teeth: B. exodon, B. microcephalus and B. iheringii groups. Few cytogenetic data are available for this genus, but the diploid number of 52 chromosomes is quite common, although the karyotypic variability is extensive.

A new species of Acestrocephalus (Characiformes: Characidae) from Venezuela.
Revista de biologia tropical, 2000 A new species of Acestrocephalus is described from 60 specimens collected in the Río Orinoco and Río Negro drainages, Venezuela. This species is distinguished. from aH other Acestrocephalus by the combination of the foHowing characters: anal rays, 29-36; 63-71 perforated scales on (he lateral line; 10-12 scales aboye and 9-12 below the lateral line; 39-

Ecology and Evolution, Volume 16, Issue 1, January 2026.This study successfully decoded the complete mitochondrial genomes of two Moenkhausia species, with total lengths of 16,439 and 16,461 bp, respectively. This study enhances genomic resources for Acestrorhamphidae and provides a foundation for investigating evolutionary mechanisms and developing molecular markers.

Inheritance of Trunk Banding in the Tetra (Gymnocorymbus ternetzi Characidae) [PDF]
Journal of Heredity, 2004 The tetra (Gymnocorymbus ternetzi) exhibits two phenotypes associated with trunk banding. Fish possess either a smoky-gray coloration with two prominent black vertical bands located directly behind the operculum (black tetra) or a lighter coloration and lack these bands (white skirt tetra).

Ecology and Evolution, Volume 16, Issue 1, January 2026.From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...
