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.

Mydrosoma sabarensis sp. n. is described from the Atlantic Forest Domain of southeastern Brazil. Two females and one male were collected on flowers of Serjania sp. (Sapindaceae) in the state of Minas Gerais. An additional female is from Domingos Martins, Espírito Santo state. The female M. sabarensis is about 12 mm long, robust, with predominantly black pubescence but with a wide transverse band of white hairs on the anterior margin of the mesoscutum and yellow lateral bands on T2–T4. The male, about 11 mm long, has pale-fulvous pilosity on the mesosoma and marginal bands on T1–T4, with terga blackish pubescent basally. A key to the five species of Mydrosoma known to occur in Brazil is presented and the classification of the Dissoglottini is discussed. Aspects of foraging and of possible mimicry are also discussed.

We describe a new species of dull-colored flea-toad, genus Brachycephalus, from the Atlantic Forest of Caparaó mountains in southeastern Brazil. The new species is characterized by its diminutive size, “leptodactyliform” body, brownish color with an inverted V-shaped dark mark on dorsum, skin smooth, hyperossification and dorsal shield absent, linea masculinea absent, Fingers I and IV vestigial, Toe I externally absent, Toe II reduced but functional, Toes III and IV with pointed tips, Toe V vestigial, and ventral color uniformly brown. It is a leaf litter dweller, known only from type locality in the humid forests on the eastern slopes of Parque Nacional do Caparaó mountains, a protected area in the states of Espírito Santo and Minas Gerais, southeastern Brazil. It is the third flea-toad occurring in the state of Espírito Santo recovered as sister to all other Brachycephalus distributed from the state of São Paulo northward in the Atlantic Forest.

Specimens of Gripopterygidae (Plecoptera) from Espírito Santo State and surrounding areas in the state of Minas Gerais, southeastern Brazil, were studied. A new species, Gripopteryx caparao n. sp. is described. The female of Paragripopteryx intervalensis Bispo & Lecci 2011 is described and recorded for a new site. Comments on G. garbei Navás 1936 are presented. New state records are provided for G. cancellata (Pictet 1841), G. reticulata (Brauer 1866), G. juetah Froehlich 1990, G. pilosa Froehlich 1990, P. egena Froehlich 1994, P. intervalensis Bispo & Lecci 2011, P. klapaleki Enderlein 1909, and Tupiperla gracilis (Burmeister 1839).

A new species of Mimosa is described from the Atlantic Rainforest and ecotone with the Cerrado of southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and São Paulo: M. porrecta L. Jordão, M.P. Morim & Baumgratz (Leguminosae). Related to M. sensitiva, it shares morphological affinities with this species but differs in having porrect-stellate trichomes, a new type of trichome for the genus, on the stems, and the dendritic trichomes in the fruits. The conservation status was assessed, according to IUCN criteria, as Least Concern.

The Chimanimani Mountains, located at the Mozambique-Zimbabwe border, are geologically unique in that they consist of quartzites giving rise to peaks and outcrops between zones of schist supporting grasslands. The nutrient-poor quartzitic soils house a high number of endemic plant species. One of these is Sericanthe chimanimaniensis, which is here described as new for science. We give a detailed description and distribution map, illustrations, information on ecology and phenology, and an assessment on the conservation status. An identification key to closely allied species is presented.

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.

Schoenus is a predominately austral genus of sedges in which the Southern African taxa have recently received detailed taxonomic attention, starting with a transfer of 24 species into Schoenus from Tetraria and Epischoenus in 2017. The taxonomy of the Southern African Schoenus species is currently being revised, which has brought insight into the existence of several species new to science. Here, we build on this recent taxonomic work by describing one new species that has been previously overlooked (Schoenus inconspicuus), while including a distribution map, an assessment of conservation status and an updated identification key.

Penstemon dugesii is described from the central region of the state of Guanajuato, Mexico. This species belongs to Penstemon subg. Penstemon sect. Fasciculus. Here, we describe this new species and compare it with P. coriaceus, to which it is morphologically most similar. We also propose its conservation status and provide a distribution map of both species.

At present, 13 species of Hyalella are recorded from Brazilian hydrographic basins. A new species of the genus was foundin the municipality of Arcos, Minas Gerais state and it is described here. Curved seta on inner ramus of male uropod 1,posterior margin of gnathopod 2 propodus shorter than palm, telson longer than wide are some of the diagnostic charatctersof this new species. The articles of maxillipod palp and propodus of gnathopod 2 are elongated as observed in H.longistila,but the new species differs from it because of the curved seta on uropod 1. Despite being large and diverse group, Hyalellais represented only by two species in the state of Minas Gerais (Southeastern Brazil), H. warminig and H. gracilicornis.The distribution of H. longistila, previously recorded in Rio de Janeiro state, was extended to Minas Gerais state. Thiswork, therefore, contributes for the knowledge of Amphipoda fauna from Brazil, describing a new species and providing a key to the species identification. From this work, the number of Hyalella species found in Brazil to 14.
