Última The brain of Brycon orbignyanus (Valenciennes, 1850) (Teleostei: Characiformes: Bryconidae): gross morphology and phylogenetic considerations Neotropical Ichthyology Pereira,Thiago N. A.; Castro,Ricardo M. C.. ABSTRACT The brain of Brycon orbignyanus is described as a model for future studies of the gross morphology of the central nervous system in Characiformes. The study of brain gross morphology of 48 distinct taxa of Characiformes, one of Cypriniformes, two of Siluriformes and two of Gymnotiformes, allowed us to propose, for the first time, six putative brain synapomorphies for the Characiformes and also two possibly unique gross brain morphology characters for the Siluriformes. A detailed protocol for the extraction of the brain in Characiformes is also provided.

A.; Castro,Ricardo M. C.. Utiaritichthysesguiceroi is described from the upper portion of the rio Juruena, rio Tapajós drainage, Mato Grosso State, Central Brazil. The new species distinguished from its two congeners, U. sennaebragai Miranda Ribeiro and U. longidorsalis Jégu, Tito de Morais & Santos, by having 99 to 101 perforated scales on lateral line (vs. 69 to 83), presence of 17 to19 prepelvic spines (vs. 9-13 in U. sennaebragai and 28-31 in U. longidorsalis), 20 to 21 postpelvic spines (vs. 15 to 19 in U. sennaebragai, and 14 in U. longidorsalis), and 23 to 25 circumpeduncular scales (vs. 30-48 in U. sennaebragai, and 33-35 in U. longidorsalis). Furthermore, the new species differs from U. longidorsalis by having larger interdorsal width, and adipose-fin base length...
