Abstract

The subfamily Bryconinae includes middle to large-sized fishes, distributed from southern Mexico to the Rio de La Plata in Argentina, and at the western versant of the Andean cordillera from Venezuela to Peru. Species from the subfamily are highly regarded and are among the most sought fishes in commercial, subsistence and amateur fisheries whenever they occur. Recent estimates by the author of the proposal put in 48 the number of recognizable species within the subfamily. The precise phylogenetic position of Bryconinae within Characidae is still a matter of dispute, but there is a relative consensus in considering both by morphological and molecular evidence the subfamily as basal within the family. In spite of the fact that considerable advances both in the taxonomical knowledge of the main genus withn the subfamily, Brycon, as well as the phylogenetic relationships within the subfamily have taken place in the last few years, several important questions on the taxonomy and phylogenetic relationships within Bryconinae remain to be elucidated. This project aims to fill the remaining gaps on the taxonomical and phylogenetical knowledge of the subfamily, which are the taxonomy from the species of the genus Brycon occurring at trans-Andean South America and Central America, the taxonomy of the Brycon pesu species complex, and to collaborate with ongoing phylogenetic hypothesis, both morphological and molecular on the subfamily, using the resulting hypothesis to understand vicariant events that might explain the current geographical ranges from the of Bryconinae.
