A cladistic analysis of the genus Atlantodesmus Hoffman, 2000 is presented. With a total of 11 taxa and 30 morphological characters, and under implied weighting (k = 3), two equally most parsimonious trees (length = 58 steps; total fit = 23.150; CI = 0.64; RI = 0.64) recovered the monophyly of the genus. The resulting synapomorphies are: absence of a ventral projection on the post-gonopodal sternites; presence of folds on the dorsal edge of the prefemoral region of the gonopod; and one homoplastic transformation: presence of a cingulum. In addition, Atlantodesmus sierwaldae sp. nov. is described from the state of Minas Gerais, in the Brazilian Cerrado, and a key to the males of the genus is provided.

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).

During a floristic survey of Melastomataceae carried out in Delfinópolis and Capitólio, Minas Gerais State, Brazil, a new species of Fritzschia was found. Fritzschia furnensis has stems peeling in thin, woody flakes, petiole 2–10 mm long, large leaf blades (23–38 × 10–29 mm) and an indumentum of glandular trichomes on the branches, petioles, leaves, bracteoles, pedicels, hypanthia, and sepals. The new species is regarded as endangered (EN) due to a restricted distribution, small populations and the destruction of its habitat.

At the time the genus Attacobius Mello-Leitão, 1925 was first acknowledged as a member of the subfamily Corinninae, Corinnidae, by Platnick & Baptista (1995), only three species were recognized. Since then, that number has increased to 15 currently valid species (Bonaldo & Brescovit 1998; 2005; Pereira-Filho et al. 2018). Recently we had the opportunity to discover an additional species of Attacobius, collected in association with fire ants of the genus Solenopsis Westwood in the State of Goiás, Midwest Brazil, a region that harbors a large portion of the Brazilian Cerrado, one of the most threatened savannas in the planet. Attacobius lavape n. sp., described below, appears to belong to the same group of species as A. verhaaghi Bonaldo & Brescovit, 1998 and A. lamellatus Bonaldo & Brescovit, 2005, since these three species share, in the male palp, the presence of an unsclerotized median lobe on the retrolateral tibial apophysis (Figs 9, 11).

We describe a new species of Amphisbaena based on a single specimen collected in the northern Brazilian Cerrado,municipality of Loreto, state of Maranhão, Brazil. The new species is characterized by presenting a unique combinationof characters including: absence of precloacal pores, body annuli 306, caudal annuli 21, autotomic site in the eighth postcloacal annulus, dorsal sulci absent, 10 dorsal segments and 14 ventral segments in a midbody annulus.

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).

Dendrocephalus thieryi nov. sp., discovered in the state of Minas Gerais, Brazil, is described. The new species is defined by a unique morphology of its male frontal appendage and of the endopodites of the first four thoracopods. A dichotomous key to all known Dendrocephalus species based on male morphology is presented.

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.

The spider family Nesticidae includes 233 species in 13 genera and is distributed almost worldwide (World Spider Catalog, 2016). However, the family is still poorly known in the Neotropical Region. The genus Nesticus Thorell, 1869 comprises 132 species and seven subspecies and was described based on N. cellulanus (Clerck, 1757), from Europe (World Spider Catalog, 2016). Meridional South American species of Nesticus were revised by Ott & Lise (2002). More recently, Faleiro & Santos (2011) described a new species from the state of Minas Gerais, Brazil and Torres et al. (2016) a new species from the province of Salta, Argentina. Nowadays, Nesticus is represented by six species in Brazil: Nesticus brasiliensis Brignoli, 1979; Nesticus brignolii Ott & Lise, 2002; Nesticus calilegua Ott & Lise, 2002; Nesticus ivone Faleiro & Santos, 2011; Nesticus potreiro Ott & Lise, 2002 and Nesticus taim Ott & Lise, 2002 (World Spider Catalog 2016).
