Abstract


The identification of species of Apistogramma Regan, one of the most diversified cichlid genus, found in lakes Amanã and Urini, and tributaries (Amanã Sustainable Development Reserve), Japurá-Solimões drainage, Brazilian Amazon, is herein presented. Individuals of the genus collected in the area were previously classified in eight morphotypes separated in A. agassizii, A. cacatuoides and six unidentified types. After detailed analyses, it was concluded that these eight morphotypes belonged, in fact, to five species. The diagnosis for each species is presented, as well as an identification key for the area. Briefly, individuals formerly identified as Apistogramma sp.2 belong to a species, possibly yet undescribed, of Pertensis group, thus classified as Apistogramma gr. pertensis. Apistogramma sp.3 was identified as A. hippolytae and Apistogramma sp.4 as Apistogramma cf. eunotus. Individuals formerly classified as A. cacatuoides are, in fact, A. bitaeniata. Individuals formerly classified as Apistogramma sp.1 are, in their majority, young specimens of A. agassizii, and few A. bitaeniata. Individuals at first classified as A. agassizii really correspond to the referred species. The results made possible the prompt identification of occurring species, aiding additional scientific studies and the further use of these species in the ornamental fishes management by Amanã Reserve riverine communities.
