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 S~ ao 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 environ-
mental similarity, a predictive species distribution modelling has been developed. The gath-
ering 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 environ-
mental 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.

1 Introduction
The Atlantic Forest stands out for the richness of its
flora, being considered one of the richest biodiversity
ecosystems in the world (Stehmann et al. 2009), with
15,444 species of angiosperms distributed in 2,069 gen-
era and 218 families (Flora do Brasil 2020). Of the
14,552 vascular species found in the Atlantic Domain,
6,933 are endemic, which leads us to conclude that half
of all this diversity is exclusive, and corresponds to
almost 2% of the Earth’s plant species (Stehmann et al.
2009). The Melastomataceae A. Juss. family is the sev-
enth most diverse with 581 species (Flora do Brasil
2020). In contrast to all this wealth, the Atlantic Forest is
currently reduced to less than 8% of its original cover-
age due to factors such as deforestation, agriculture,
hunting, mining and disorderly urban growth (BRASIL
2010).
Serra Negra stands out as an important remnant of
the Atlantic Forest located in the southern part of the
Zona da Mata of Minas Gerais state, in the Mantiqueira
Range region, and is composed of a mosaic of forest
and grasslands vegetation, sheltering high diversity and
numerous endemisms (Salimena et al. 2013).
The region flora is represented by 1,033 taxa and
469 genera and, of this total, five species of phanero-
gams are endemic to the area and 58 are listed in the
list of endangered species of Minas Gerais (Salimena
