First records of Cheirodontinae (Actinopterygii: Characiformes: Characidae) from drainages of Espírito Santo state, southeastern Brazil

Abstract

Recent samples revealed the first occurrences of Serrapinnus heterodon (Eigenmann) in three different sample sites from two drainages in northern Espírito Santo state, Brazil. This is also the first record of the subfamily Cheirodontinae for this State, whose territory is completely inserted in the Atlantic Rainforest ecoregion. The new records of S. heterodon were found with known introduced species and far outside of its usual distribution. This leads us to believe that its presence in the region may be the result of an introduction.
