Phylogenetic study of the Characinae (Teleostei: Characiformes: Characidae) [PDF]
Zoological Journal of the Linnean Society, 2012 The Characinae is a subunit of the Characidae of special significance in including Charax, the type genus of the family and the order Characiformes. Twelve genera and 79 species have been traditionally assigned to the Characinae, but the subfamily still lacks a phylogenetic diagnosis.

Monophyly of the Agoniatinae (Characiformes: Characidae)
Zootaxa, 2013The Characidae is the most diverse family of Neotropical fishes, currently encompassing more than one thousand valid spe-cies. Some subgroups within this family still lack phylogenetic definitions, being diagnosed on the basis of combination of characters, a common procedure in pre-cladistic studies. Agoniatinae, currently composed by two valid species,

Weighted parsimony phylogeny of the family Characidae (Teleostei: Characiformes) [PDF]
Cladistics, 2009 AbstractThe family Characidae, including more than 1000 species, lacks a phylogenetic diagnosis, with many of its genera currently considered as incertae sedis. The aims of the present study are to propose a phylogenetic diagnosis and to assess higher‐level relationships of and within Characidae. In this regard, 360 morphological characters are studied

Neotropical tetras of the family Characidae form the largest and most taxonomically complex clade within the order Characiformes. Previous phylogenetic relationships concur on the recognition of four major subclades, whereas knowledge on intergeneric ...

Taxonomic review of the Hyphessobrycon panamensis species-group (Characiformes: Characidae).
Zootaxa, 2020A taxonomic review of the Hyphessobrycon panamensis species-group is presented, with recognition of six valid species. In Central America, H. panamensis was restricted to the drainages of both Atlantic and Pacific coasts of Panama; H.

Observations on tooth replacement in piranhas (Characidae)
Archives of Oral Biology, 1975Abstract Skeletal and preserved material from 15 piranha fish ( Characidae ) were examined radiographically and the heads of a further three specimens of body length 2.5–4.0 cm examined histologically. Such material revealed a close correlation in the stage of development between upper and lower dentitions on the same side of the jaws but the stage ...

Phylogenetic Analysis and Redescription of the Genus Henochilus (Characiformes: Characidae) [PDF]
Copeia, 2004 Abstract Henochilus, a characiform genus endemic to eastern Brazil is reviewed. A single species, Henochilus wheatlandii, from the Rio Doce and possibly the Rio Mucuri in the states of Minas Gerais and Espirito Santo is recognized and redescribed. The phylogenetic analysis indicates that Henochilus is most closely related to the clade consisting of ...

Intromittent Organ in the Genus Monotocheirodon (Characiformes: Characidae)
Copeia, 2006Abstract We herein document intromittent organs in four Peruvian populations of inseminating fishes of the family Characidae, genus Monotocheirodon, which may comprise new species. All females histologically analyzed from these populations, as well as a female of Monotocheirodon pearsoni, had spermatozoa within the ovary, confirming insemination.
