Astyanax dnophos, new species, is described from the lower rio Xingu, Para, Brazil. The new species is distinguished from its purported congeners by the presence of a broad longitudinal, midlateral dark stripe that extends from the snout to the caudal peduncle. Astyanax dnophos dwells on shadowed, rocky shelters on rapids, and it is apparently one of the few species of Characidae outside Serrasalminae reported to be rheophilic. 
Astyanax henseli, a new name for Tetragonopterus aeneus Hensel, 1870 from southern Brazil (Teleostei: Characiformes)
TLDR
Astyanax henseli differs from A. fasciatus stricto sensu and other Astyanax species by the presence of two to four maxillary teeth, two vertically-elongated humeral spots, dentary tooth cusps positioned close to one another, and the slender form of the dentary teeth. Expand
Two new species of Moenkhausia Eigenmann (Characiformes: Characidae) from Serra do Cachimbo, Pará, Northern Brazil
TLDR
Two new species of Moenkhausia are described as apparently endemics of the Serra do Cachimbo and share a distinct color pattern composed of large conspicuous dark blotches on the base of the body scales. Expand
A new species of Moenkhausia Eigenmann (Characiformes: Characidae) from the rio Xingu basin, Brazil
TLDR
A new species of Moenkhausia from the upper rio Xingu basin is described, distinguished from all congeners, except M. heikoi and M. phaeonota, by the presence of a dark, broad longitudinal stripe from the opercle to the end of caudal peduncle. Expand
South American electric knifefishes of the genus Archolaemus (Ostariophysi, Gymnotiformes): undetected diversity in a clade of rheophiles
TLDR
Neotropical electric knifefishes of the family Sternopygidae were analysed and found to represent a complex of five species, four of which are new to science, and the genus found to be the most specious clade within the Gymnotiformes living primarily in high-energy settings. Expand
Astyanax bockmanni Vari and Castro, 2007: an ambiguous karyotype in the Astyanax genus
TLDR
Cytogenetic studies were performed in two populations of Astyanax bockmanni, revealing conservative features of this species, and the studied species combines a set of characteristics previously identified in two differentAstyanax groups. Expand
Electric fishes of the genus Sternarchorhynchus (Teleostei, Ostariophysi, Gymnotiformes); phylogenetic and revisionary studies
TLDR
A phylogenetic reconstruction of the Neotropical electric knifefish genus Sternarchorhynchus (Apteronotidae; Gymnotiformes) yielded a hypothesis that it is the sister group to Platyurosternarchus, and a series of synapomorphies, many involving major innovations of the neurocranium, jaws, suspensorium, and associated systems support the monophyly of both genera.
