Abstract
This study is a contribution to the taxonomy of Calyptranthes and to the list of Brazilian species of Myrtaceae. It presents morphological circumscriptions and new records of occurrences for the genus, and proposes a new synonym for C. moaensis Alain. Comments are made on the morphologies of the taxa and identifications of each species are provided, as well as discussions about their taxonomic affinities, geographical distributions, and preferred habitats in the Amazon region. New records include one for the Amazon region and five for Pará State.
