“…; Montini & Romero ). The genus Pleroma D. Don has over 160 species of trees, shrubs or herbs, which occur in the Atlantic rain forest in eastern Brazil, in drier areas (cerrado and caatinga) located in central and northeastern regions of the country and northwestern and western South America (Fraga & Guimarães ; Guimarães & Silva ). This genus presents its greatest diversity in the Atlantic Rain Forest, with almost 90 taxa (Goldenberg et al.…”

This paper presents the first record of Pleroma boraceiense in Minas Gerais state, Brazil. This new occurrence is significant because the species had a restricted original distribution with about 10 gatherings in São Paulo State, in the Serra do Mar. On the other hand, a previous study showed a low floristic similarity between the Melastomataceae flora of the Serra do Mar State Park and that of Serra Negra region. In order to evaluate the environmental similarity, a predictive species distribution modelling has been developed. The gathering site in Minas Gerais (RPPN Mato Limpo) showed high suitability. It suggests the need for creation of protected areas in Serra Negra, since the region is suffering environmental impacts. Based on the recent phylogeny of the Melastomateae tribe and for the purpose of correct classification of the studied species, a new combination was made for Pleroma boraceiense.

Tibouchina (Melastomataceae: Melastomateae) is an exclusively Neotropical genus that currently includes close to 310 species. These were first described or assigned to 16 other genera, a reflection of the complex taxonomic and phylogenetic history of the genus. Previous phylogenetic analyses have shown that the genus is polyphyletic. Here we present an expanded analysis that includes representatives of 28 genera of New World Melastomateae, as well as representatives of Old World Melastomateae and members of the Marcetieae and Microlicieae. Over 300 species were sequenced for nrITS and the plastid spacers accD‐psaI and psbK‐psbL. We recovered a large clade of Neotropical Melastomateae that contains Tibouchina along with at least 13 other Neotropical genera. Moreover, Tibouchina is not recovered as monophyletic because three mostly Central American and five mostly Andean genera are nested within it, albeit each these genera are recovered as monophyletic. Many of the previously recognized sections of Tibouchina are recovered as monophyletic or paraphyletic providing a basis for a new classification. Tibouchina is here re‐circumscribed into four genera that are each monophyletic and easily diagnosable. This results in a narrowly circumscribed Tibouchina and the re‐establishment of Pleroma and Chaetogastra, and the description of a new genus, Andesanthus. Pleroma now also includes Itatiaia, Microlepis and Svitramia. Brachyotum is maintained until its relationship to Chaetogastra can be further examined. This new taxonomic arrangement is more informative and convenient than merging eight other genera into Tibouchina. An identification key, descriptions of genera, and lists of taxa with their current generic assignment and necessary nomenclatural novelties are also presented here.
