Begonia piranga (Begoniaceae) is a new narrowly endemic species from the campos rupestres of Serra do Padre Ângelo, a quartzitic massif in Conselheiro Pena, eastern Minas Gerais state, Brazil. Description, diagnosis, taxonomic comments, detailed illustrations, field photographs, and a provisional IUCN Red List Assessment are provided. The new species is considered Critically Endangered due to its restricted occurrence in high elevation rock outcrops, small population size, and decline in the quality of the habitat. Begonia vasconcelosiana, another Critically Endangered species, is also newly reported here for Serra do Padre Ângelo. These discoveries add to the increasing list of novelties from Serra do Padre Ângelo, reinforcing the urge for conservation actions to protect the endemic flora of this Serra and other areas of campos rupestres in eastern Minas Gerais state.

Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

This paper describes the composition and distribution of Anisoptera and Zygoptera (Odonata) species of the upper Rio das Velhas in the municipality of Ouro Preto, Minas Gerais State, Brazil. A total of 727 specimens of 40 species were collected near water bodies over a period of 23 months between 2015 and 2017. The families with greatest species richness were Libellulidae (13 species), Coenagrionidae (12 species) and Heteragrionidae and Aeshnidae (4 species each). Notable among the species collected were Perilestes fragilis Hagen in Selys, 1862, inhabiting well-preserved forests, Minagrion waltheri Santos, 1965, pertaining a endemic genus of Brazil and the recently described Heteragrion cauei Ávila-Júnior et al., 2017, and three species recorded for the first time for the state: Elasmothemis alcebiadesi (Santos, 1945); Erythrodiplax melanica Borror, 1942 and Erythrodiplax acantha Borror, 1942, the latter is considered Critically Endangered (CR) by the International Union for Conservation of Nature's (IUCN) Red List.

We described a new species of Phyllanthus currently known from a single fragment of Ombrophilous Dense Forest in the Jequitinhonha Valley, Minas Gerais State, Brazil. Phyllanthus pedicellatus is the second species of the genus with phylloclades found in the Atlantic Forest domain, once mostly Brazilian Phyllanthus with these kinds of specialized branches grow in open vegetation as “campos rupestres” and cerrado. The name is a reference to its remarkable pedicels of pistillate flowers. We present illustrations and photographs of the new species in its habitat, comments on its relationships to other Brazilian Phyllanthus, and its conservation status.

Two new species of Pseudotrimezia are described and illustrated. Both species are endemic to localities of “campos rupestres” in Diamantina Plateau, Minas Gerais State, Brazil. Pseudotrimezia nana is remarkably distinguished by the overall size, one of the smallest within the genus, bracts on the flowering stem and leaf anatomy. Pseudotrimezia striata is noteworthy due a partly bifacial leaf that encloses the flowering stem. Morphological comparisons with similar species are also provided.

Abstract—Three new species of Eriocaulaceae, endemic to the Serra da Canastra in Minas Gerais state, are described. Paepalanthus petraeus is assigned to P. ser. Paepalanthus, differing within the series by its thickened stem accumulating leaf sheaths, linear leaves, and numerous scapes shorter or equaling the leaf height and bearing capitula with brown involucral bracts. Paepalanthus sinuosus belongs to P. subsect. Polyactis and is distinguished by few scapes in lax fascicles, more than twice as long as the leaves, which are patent to slightly recurved, and light brown involucral bracts with acute apex. Syngonanthus culcitosus, within S. sect. Syngonanthus, is unique due to its elongate and branched stem forming dense mats, simple inflorescences, cream-colored involucral bracts equaling the length of the floral disc, and gynoecium with nectariferous appendages. Comparisons with the most similar species are provided for each new taxon. Maps, photographs, and illustrations are presented, together with comments on phenology, distribution, habitat, and morphology. Paepalanthus petraeus and P. sinuosus are likely to be assessed as Critically Endangered, and S. culcitosus as Vulnerable, according to IUCN criteria.

Microlicia furnensis, a new endemic species from campos rupestres of Capitólio municipality, Minas Gerais state, Brazil, is described and illustrated. The new species is characterized by its cream petals with pale pink blotches at the apex, sessile or subsessile leaves and golden glandular trichomes and short pale trichomes covering the leaves, pedicels, hypanthium and the calyx lobes. It resembles M. confertiflora, M. isophylla and M. flava, the latter also occuring in Capitólio, Minas Gerais state. A list of species of Melastomataceae from the mountains of Capitólio municipality is also provided.

Lychnophora osanyiniana is a new species from “campos rupestres”, a Brazilian savanna ecosystem constantly threatened by agriculture and mining, despite it having a high number of plant species, particularly endemic and microendemic species. The new species was collected from Sítio Serra da Rita, Serra dos Alves, municipality of Itabira, Minas Gerais State, Brazil. The species is recognized by its glomerulate capitulescence with subinvolucral bracts surrounding sessile heads, giving the appearance of a single head. Another distinct character, although it is not exclusive, is an uniseriate pappus, shared by just three species, Lychnophora grisea, L. haplopappa and L. uniflora, of which only L. haplopappa has similar habit, becoming the closest species.

Chrysolaena glandulosa is a new species of Vernonieae (Asteraceae), endemic to the “campos rupestres” of Serra da Canastra National Park and adjacent areas of southwestern Minas Gerais state, Brazil. Chrysolaena glandulosa is characterized by its laxly disposed leaves and lower surface with glandular dots, corolla lobes papillose with glandular dots, and strigose achenes with glandular dots. It is morphologically similar to C. campestris but differs from the latter by presence of glandular dots on the lower surface of the leaves, the ratio between the size of the bracts of the inflorescence and the involucre, and the number of heads and flowers per head. Pollen study confirms that this species belongs to Chrysolaena. A diagnostic key is presented to all Minas Gerais species.

Astyanax brucutu is described from the rio Pratinha, rio Paraguaçu basin, Bahia, Brazil. The new species is promptly distinguished from other characids by having four, rarely three, robust, rounded, and usualy tricuspid teeth on inner premaxillary series and similar teeth on dentary. The species is furthermore characterized by a series of unusual character states in the Characidae, including head blunt in lateral and dorsal views, longitudinal foreshortening of lower jaw, ventral margin of third infraorbital distinctly separated from horizontal limb of preopercle, leaving a broad area without superficial bones, mesethmoid anteroventrally expanded, and adductor mandibulae and primordial ligament remarkably developed. Analysis of gut contents of adults revealed the almost exclusive presence of crushed shells of tiny gastropods of the family Hydrobiidae. The robust anatomy of jaws, teeth, muscles and associated ligaments are likely adaptations to durophagy, a feeding strategy unusual among characids. Astyanax brucutu is known only from its type locality, an approximately 670 m long, transparent and isolated perennial epigean watercourse surrounded by subterranean or intermittent rivers. The distinctive combination of environmental features characterizing the area of occurrence of the new species is not observed elsewhere in the basin or adjacent basins. A series of severe anthropogenic impacts, associated with the restricted geographic range of the species, implies that A. brucutu should be regarded as Critically Endangered (CR) according to IUCN Red List Criteria.
