Update on the checklist of fish species of the Bolivian Amazon

In 2010 and 2011 new checklists of fish species occurring in the Bolivian Amazon have been published. We add 21 species to these lists of which two are new reports for Bolivia ( Apistogramma urteagai Kullander, 1986 and Vandellia sanguinea Eigenmann, 1917). The other 19 taxa have been reported earlier for the Bolivian Amazon. Their absence on previous checklists indicate the difficulties to compile an overview of the current literature on the fish fauna of the Bolivian Amazon. The ichthyofauna of Bolivia is still not entirely known and many species await formal descriptions. Future collection efforts and taxonomic reviews might rise the number of known Bolivian fish species considerably in the near future.
