ABSTRACT The objective was to present the floristic survey of the bryophytes of the Parque Estadual da Serra do Brigadeiro. It included an evaluation of the species richness, as well as information about the substrate preference of each species and its geographic distributions in Brazil. We found 208 taxa of bryophytes: one hornwort, 88 liverworts and 119 mosses. This richness represents ca. 26% of the bryoflora of Minas Gerais State and ca. 13% of that known for Brazil. Eighteen of the bryophytes species are endemic to Brazil, whereas 19 species are recorded for the first time in Minas Gerais. The bryoflora showed preference for tree bark (30%) and rock (23%) as substrates. Our data show that the Parque Estadual da Serra do Brigadeiro is an important area for the diversity conservation of Brazilian bryophytes and maintenance of endemic species of the country.

Hyptidendron albidum a new and endemic species from Northern Minas Gerais state, Brazil, is here described. This new species is unique due to the morphological combination of its dense indumentum of white dendroid trichomes, covering much of the plant and the inflorescence composed of a unilateral cymose structure. The new species is morphologically similar to H. unilaterale which displays a similar unilateral cymose structure but differs in its indumentum, inflorescence length and leaf morphology. We provide a description, an illustration, a conservation status assessment, a distribution map, and comments on the recognition of this new species.

We report new records of the recently reestablished Lamanonia ulei (Engl.) L.B.Sm. (Cunoniaceae) from southeastern Brazil. This species is currently known by only eight specimens from Minas Gerais, Rio de Janeiro, and São Paulo states. We present seven new records that include Espírito Santo state in the species distribution, and expand its north and east limits of occurrence. We also present a taxonomic description, photos, occurrence map, conservation status assessment of L. ulei, and an identification key for all the species of Lamanonia Vell. from Brazil.

A new species of Calea sect. Calea, endemic to the rocky grasslands of the municipality of Diamantina, Minas Gerais, southeastern Brazil, is described. Calea diamantinensis is morphologically similar to Calea lantanoides which differs by its leaf blade elliptic (vs. ovate to widely ovate), margin entire and straight (vs. crenate and revolute), surface solely glandular-punctuated (vs. villous), receptacle paleae obtrullate (vs. narrowly elliptic), capitulescence composed by 3–4 heads (vs. 6–12 heads), cypselae glandular-punctuated ca. 2.7–3 mm long (vs. non-glandular, ca. 1.8–2.5 mm long) and pappus scales ca. 15–17 (vs. 20–25). Illustration, photos, distribution map, habitat considerations and conservation status are provided, as well as an identification key for Calea species from the municipality of Diamantina, Minas Gerais.

The Espinhaço Mountain Range in Minas Gerais state in southeastern Brazil is a center of endemism of the Bromeliaceae, mainly in campo rupestre montane vegetation that grows under rigorous edapho-climatic conditions. This study sought to improve our knowledge of the Bromeliaceae from Serra da Piedade in the extreme southern portion of the Espinhaço Mountain Range where ironstone outcrops predominate. Conservation status and spatial distribution of these plants were analyzed as well as floristic similarities with other regions with rocky outcrops. Twenty-five bromeliad species were found in Serra da Piedade, with the subfamily Tillandsioideae being the best represented. Twenty-seven percent of the species were exclusive to campo rupestre environments, while 73% occurred both on outcrops and in forest habitats. The bromeliads in the study area merit special attention as two species are considered vulnerable (Racinaea aerisincola and Vriesea minarum), five are endangered, and three are critically endangered. Low Jaccard index values indicated dissimilarities between the bromeliad floras in different localities of quartzite and ironstone outcrops within the Espinhaço Mountain Range. Serra da Piedade has a distinct bromeliad flora that is threatened by mining activities and illegal harvesting and requires immediate measures to help guarantee conservation.

Conservation Actions

Studies about the birds of rupestrian fields in the south of Minas Gerais State in Southeastern Brazil are incomplete, although this region is ornithologically well studied. This bird community has closely associated ecology with fields and the most endangered species of the Cerrado domain. The objective of this manuscript is to create a list of birds which occur in the rupestrian fields of seven municipalities in the south of Minas Gerais State, and further to analyze the birds’ distribution, the endangered species (and their conservation status), and generate bases for future conservation actions. We evaluated seven cities in the south of Minas Gerais State between 2012 and 2018 by using binoculars and cameras. We found a high richness in relation to other open areas, with the Tyrannidae and Trochilidae families being the most representative. We highlight the endangered species in the Cerrado domain which of these species are closely linked to rupestrian fields. The composition is similar to closer areas, with exception to São Thomé das Letras city because it suffers an influence of mining areas. We suggest creating a wildlife protected area to preserve and conserve a great area of rupestrian fields and consequently the associated biota, especially the bird communities

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.
