Pouteria. s. s. (Chrysophylloideae) includes ca. 200 species, representing the largest genus of Sapotaceae. In Brazil, 120 species are recorded in Amazonia and in the Atlantic Rainforest where the genus is centered. This paper presents a taxonomic survey of the 34 species of Pouteria s. s. from the northern portion of the Atlantic Rainforest of Brazil, and includes an identification key, nomenclatural updates, new synonyms, descriptions, and detailed information about geographic distribution and phenology for all taxa, and illustrations. Species of Pouteria are mainly separated based on leaf venation, trichome type, stamen and stamirtode morphology, and fruit traits. Out of the 34 species recognized, 18 are endemic to the Atlantic Rainforest of Brazil, 10 are disjunctly distributed with Amazonia, and six are widespread in South America. According to the IUCN red list criteria, 20 of the 34 species treated here are threatened; of these, 10 are vulnerable, seven are endangered, and three are critically endangered.
