Resumo:  The aim of the present study was to compare the component parasite communities of the Pterophyllum scalare and Mesonauta acoracichlids in the Amazon River system in northern Brazil. From September to December 2012, 42 specimens of P. scalareand 38 specimens of M. acorawere captured using hand nets and gillnets in the Igarape Fortaleza basin, a tributary of the Amazon River in the state of Amapa. Of the P. scalarespecimens examined, 97.6% were parasitized by Ichthyophthirius multifiliis, Tripartiellasp., Trichodina nobilis, Gussevia spiralocirra, Posthodiplostomum sp., Capillaria pterophylli, Ichthyouris sp. and Gorytocephalus spectabilis. Similarly, all specimens of M. acorawere parasitized by I. multifiliis, Tripartiellasp,T. nobilis, Sciadicleithrum joanae, Posthodiplostomum sp., Pseudoproleptus sp., Ichthyouris sp. and G. spectabilis. However, for both hosts the dominance was of I. multifiliisand with an overdispersion of parasites. Parasite communities of P. scalare and M. acorawere similar and only Pseudoproleptussp. and Posthodiplostomum sp. were larvae. Brillouin diversity, parasite species richness and evenness were higher forM. acorathan for P. scalare, which presented a negative correlation of parasite abundance with body size. Both cichlid species had parasite communities characterized by low diversity and low species richness, with a predominance of ectoparasite species and greatest richness of helminth species, with a low abundance of endoparasites. This was the first study on the parasite diversity in wild P. scalareandM. acora.
