TL;DR: 16 of the 17 species of cichlid fish registered from the La Plata drainage of Bolivia can be referenced with voucher specimens in museum collections and an identification key is provided for the cichLid fish species of the study area.
Abstract: In comparison with the Bolivian Amazon, the ichthyofauna of the La Plata drainage of Bolivia received relatively little attention historically. Until now, 14 species of cichlid fish have been registered from this area. After an exhaustive review of museum collections (Museo de Historia Natural Noel Kempff Mercado y Coleccion Boliviana de Fauna), we can report three additional species: Astronotus crassipinnis (Heckel, 1840), Mesonauta festivus (Heckel, 1840) and Satanoperca pappaterra (Heckel, 1840). Four other species, which have been listed in previous publications, can be confirmed for the La Plata drainage of Bolivia based on the examination of voucher specimens: Aequidens plagiozonatusKullander, 1984, Apistogramma commbrae (Regan, 1906), A. trifasciata (Eigenmann & Kennedy, 1903) and Crenicichla vittata Heckel, 1840. As such, 16 of the 17 species can be referenced with voucher specimens in museum collections. We also provide an identification key for the cichlid fish species of the study area.

TL;DR: In this article , two new species of Bujurquina are described from the Bolivian Amazon basin: B. oenolaemus and B. vittata, which are distinguished from its congeners in the combination of the following characters: longer snout, deeper head, body and caudal peduncle, shorter pectoral fin, more scales in the E1 series, discontinuous longitudinal band, bars 5 and 6 not fused, preopercular spot and coloration pattern on flank scales absent.
Abstract: Abstract Two new species of Bujurquina are described from the Bolivian Amazon basin. The first new species inhabits the Beni River drainage and is distinguished from its congeners in the combination of the following characters: longer snout, deeper head, body and caudal peduncle, shorter pectoral fin, more scales in the E1 series, discontinuous longitudinal band, bars 5 and 6 not fused, preopercular spot and coloration pattern on flank scales absent. The second new species inhabits the Mamoré and Iténez river drainages, and differs from its congeners in the combination of the following characteristics: longer and deeper head, longer snout and pectoral fin, deeper caudal peduncle, fewer scales in the E1 series and lower lateral line, preopercular spot absent, bars 6 and 7 separated from longitudinal band and discontinuous longitudinal band. An identification key for species reported from Bolivia and complementary morphological data for B. oenolaemus and B. vittata are presented.
