Seven new species of the spider genus Matta are described from caves in the State of Minas Gerais, Brazil: M. zuiuda sp. n., Matta pititinha sp. n., Matta humhum sp. n., Matta cambito sp. n., Matta humrrum sp. n., Matta nuusga sp. n., and Matta teteia sp. n. Among these seven species, six have morphological features consistent with specialization to the subterranean environment and we hypothesize that they are troglobites. One species, Matta zuiuda sp. n., shares morphology similar to M. hambletoni Crosby and M. angelomachadoi Brescovit which are known from surface populations in the State of Minas Gerais.

Lines Of Evidence

Croton (Euphorbiaceae) includes more than 1,300 accepted species and new species of the genus are continuously being described, which are mainly from Brazil. Two new species, Croton aemulus and C. graomogolensis, are herein described, placed in C. sect. Barhamia subsect. Barhamia, and compared to C. muscicapa and C. longibracteatus. The new species are supported by their geographic distributions, ecology, and anatomical and morphological features. Both species are only known from the state of Minas Gerais, Brazil. Croton aemulus occurs in cerrado de altitude (mountain savannah) and C. graomogolensis occurs in campo rupestre (rupestrian grasslands) vegetation.

Abstract—Seven new species of the neotropical genus Microlicia are proposed (Microlicia capitata, M. coriacea, M. mutabilis, M. piranii, M. polychaeta, M. repanda, and M. sparsifolia). All seven species are known only from the state of Minas Gerais, Brazil, mainly in the Diamantina Plateau and/or the Serra do Cabral. Diagnoses, line drawings, distribution maps, notes on diagnostic characters, conservation assessments, and habitat and phenology are provided.

A New Species

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.

Two New Species

Two new species of the genus Charinus are described from caves of Brazil: Charinus spelaeus sp. n., the fourth described species of the genus for the state of Minas Gerais, and Charinus santanensis sp. n., the sixth described species of the genus for the state of Bahia. Charinus spelaeus sp. n. has reduced median and lateral eyes, and is the sixth troglobitic Charinus described for Brazil. We present here an updated key and a distribution map for all the Brazilian species of Charinus.

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).

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.

A New Species

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).
