Until now, 14 species of cichlid fish 13 have been registered from this area. After an exhaustive review of museum collections 14 (Museo de Historia Natural Noel Kempff Mercado y Colección Boliviana de Fauna), we can 15 report three additional species: Astronotus crassipinnis (Heckel, 1840), Mesonauta festivus 16 (Heckel, 1840) and Satanoperca pappaterra (Heckel, 1840). Four other species, which have 17 been listed in previous publications, can be confirmed for the La Plata drainage of Bolivia 18 based on the examination of voucher specimens: Aequidens plagiozonatus Kullander, 1984, 19 Apistogramma commbrae (Regan, 1906), A. trifasciata (Eigenmann & Kennedy, 1903) and 20 Crenicichla vittata Heckel, 1840.
