Abstract The importance of continuously conducting botanical inventories has been questioned in recent decades, generating a lack of investment and interest in this area. However, several applied studies are only possible after obtaining the primary data from such surveys. Despite having the greatest richness of plants known in Brazil, several areas with knowledge gaps remain in Minas Gerais (MG) state. This is the case for the Serra da Mantiqueira, an important area for biodiversity conservation in the country. In this scenario, the phytophysiognomy of Seasonal Semi-deciduous Forest (SSF) deserves attention, as it is broadly distributed and has great relevance in the state, although subsampled. Therefore, this study aimed to present records of species for the flora of MG and discuss the need for floristic surveys in Brazil. These species were recorded in three of 10 studied remnants along expeditions performed between the years of 2012 and 2019 as part of a wide study performed in SSF remnants in the Serra da Mantiqueira which have a deficit of floristic data. Three species are recorded for the first time in MG, one species was rediscovered after more than two centuries from the last collection (which represents its nomenclatural type), in addition to nine other species which must be considered rare in the state. This study contributed to filling gaps in knowledge on Brazilian flora and also demonstrated the relevance of continuing new collections, mainly in specific subsampled areas in the interior of the country such as in SSF remnants.

Mineralogical Assemblage

AbstractFluorapatite with monazite-(Ce) and xenotime-(Y) microinclusions occurs in the lithium–caesium–tantalum pegmatite body A of the Volta Grande mine, Minas Gerais state, Southeast Brazil. The fluorapatite displays faint zoning, detected mainly by cathodoluminescence. Electron probe and laser ablation analyses indicate that zoning in the fluorapatite corresponds to variation in Mn and rare-earth element (REE) content. Such compositional variation is attributed to partial removal of the REE from the fluorapatite structure during a dissolution–reprecipitation process, forming monazite-(Ce) and xenotime-(Y) microinclusions in the REE-depleted zones of the fluorapatite. These inclusions exhibit an inherited geochemical signature, manifested by low Th and U concentrations when compared to monazite and xenotime crystallised from melts. Rhodochrosite and calcite inclusions are also associated with monazite-(Ce) and xenotime-(Y) and are probably products of the same process, recycling Ca, Mn, and CO32− from the fluorapatite through the following reaction: [Ca(5–2a–b–½x),Naa,(Y + REE)a,Mnb][(PO4)3–x(CO3)x(F)] + Fluid[a(2Ca2+ + P5+) + (x–b)(Ca2+) + H2O)] → [Ca5(PO4)3(F,OH)] + a[(Y + REE)PO4] + b[Mn(CO3)] + (x–b)[Ca(CO3)] + Fluid a[Na+].On the basis of new fluid-inclusion analyses, we propose that a hot (T > 204.5°C), salty (16 wt.% eq. NaCl, attributed to LiCl), hydrous fluid mediated the dissolution–reprecipitation of the fluorapatite. This fluid corresponds to similarly described Li-rich fluids which were suggested to have re-equilibrated the mineralogical assemblage at the Volta Grande mine.

Hyphessobrycon uaiso is described from the upper rio Paraná basin, rio Grande drainage, Minas Gerais State. The new species differs from its congeners by the short anal fin with 12-17 branched rays, and dorsal fin with ii,7-8 rays. Besides, it can be distinguished by the presence of i,5-6 pelvic fin rays, and by the coloration of the eyes (in life), slightly blue on the lower half and blackish on the upper half. New records of Hyphessobryconare recognized for the upper rio Paraná basin: H. eilyos Lima & Moreira, H. guarani Mahnert & Géry, and H. herbertaxelrodi Géry. The knowledge status about the ichthyofauna from the upper rio Paraná basin and comments about the type material of some species of Hyphessobrycon are briefly discussed.

Abstract Senna comprises about 350 species worldwide, of which 80 species occur in Brazil. This work brings an update taxonomic treatment of Senna species in the state of Minas Gerais, the second most diverse state for the genus, through the morphological analysis of about 2,348 specimens from herbaria and fieldwork. Thirty-six species and 29 varieties were recognized, including 34 native species and 2 cultivated species. Of the 39 species reported in literature for the state, but 4 species were excluded from the list produced. The occurrence of Senna acuruensis was confirmed; S. macranthera var. striata and S. pilifera var. tubata are new records, and S. hirsuta var. acuminata is endemic to Minas Gerais. There are 28 species in the Cerrado, 26 species in the Atlantic Forest and 20 species in the Caatinga. The distribution of Senna pentagonia var. pentagonia is extended to include the Atlantic Forest. Identification keys, descriptions, illustrations, taxonomic comments and geographic distribution are provided for the species and varities.

Cebus Libidinosus

Recent compiled papers demonstrate several gaps in occurrence records and distribution limits mainly due to information deficiency, hindering the management and planning of preservation and conservation efforts. Therefore, the objective of this study is to present and analyze new records of four Neotropical Primates species: Callicebus moloch, Mico emiliae, Ateles marginatus and Cebus (Sapajus) libidinosus. Data collection was assessed by interviews, census on pre-existing trails and direct observations. The expeditions took place in the cities of Pains (Minas Gerais state), Serra do Salitre (Minas Gerais state) and Guarantã do Norte (Mato Grosso state). Mico emilie, C. moloch and A. marginatus were recorded in Guarantã do Norte and C. libidinosus was recorded in Serra do Salitre and Pains. A small expansion of occurrence area to C. libidinosus was observed. We recommend new mammal inventories in order to understand the faunal diversity in these areas and propose new conservation actions.
