Background and aims – Malanea (Rubiaceae) is a Neotropical genus of ca 40 species, 15 of which occur in Brazil, with nine found in the Atlantic Forest domain. This study aims to present a taxonomic treatment of the species occurring in the Atlantic Forest domain. Material and methods – We studied collections deposited in 15 Brazilian herbaria, ALCB, BHCB, BHZB, CEPEC, HUEFS, HUFU, IPA, JPB, MAC, OUPR, PEUFR, RFA, RB, UFP, and UFRN, and collections in NY were studied online. Specimens were identified using protologues and digital images of types available online. Key results – Of the nine species of Malanea previously recognized in the Atlantic Forest domain, we accepted seven, six of which are endemic. Malanea macrophylla has a wide distribution also occurring in other Brazilian phytogeographic domains, and adjacent countries. We expanded the distribution of four species and identified Bahia as the possible centre of diversity for the group in the domain. In addition, an identification key to the species, detailed descriptions, taxonomic notes, typifications, illustrations, maps of geographic distribution, and assessments of conservation status are provided. The names Malanea evenosa, M. forsteronioides, M. macrophylla, M. martiana, and M. spicata are here typified. The calculated conservation status revealed three Endangered species, two Vulnerable ones, M. forsteronioides as Near Threatened, and M. macrophylla with a status of Least Concern.
