A New Species

Abstract A new species of the genus Trichocline is described. Trichocline minuana is restricted to the state of Rio Grande do Sul, Brazil and northern Uruguay, where is found in lowland pampean grasslands, generally associated to rocky and dry soils. The main characters that distinguish this species from the other sympatric and morphologically close species T. humilis and T. incana are the presence of a small scape and strongly pinnatisect leaves that have lobes with acute apex, and a large, lanceolate terminal lobe. This study provides a detailed description of the species, information about distribution, conservation status assessment and information about its ecological aspects.

A New Species

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

A New Species

A new species of triadal coralsnake (Micrurus) is described from Rio Grande do Sul, Brazil. The new species differs from other Micrurus species in southern Brazil by the following characters: snout mostly black, head completely black, white gular region, triads with middle black ring 1.5 to 2 times longer than the external black rings, white rings shorter than the external black rings.  The new species occurs sympatrically with M. altirostris and adds to the following known triadal species for the region: M. baliocoryphus, M. pyrrhocryptus, M. lemniscatus, and Micrurus decoratus. Its current range is restricted to Rio Grande do Sul but it may reach adjacent areas of Argentina and Paraguay.

A New Species

(A new species of Graphis [Graphidaceae: Lichenized Ascomycota] and a revised key of the genus in Rio Grande do Sul, southern Brazil). In this paper we describe a new species of the lichen genus Graphis, namely G. suzanae Koch & Feuerstein. This species is characterized mainly by lirellae with entire labia, a partially exposed disc with orange pigment in the epithecium, a lateral thalline margin, a laterally carbonized excipulum, a clear hymenium, and transversely septate ascospores measuring 40–44 × 8–10 μm. The chemistry of the species was assessed through TLC analysis. A complete key with G. suzanae and 56 more species of Graphis that where previously recorded to the state of Rio Grande do Sul, southern Brazil, is included.

A New Species

AbstractA new species of Pseudis is described from São Francisco de Paula, Rio Grande do Sul, Brazil. It is known from the southern parts of the Serra Geral where it occurs in grassland, inhabiting permanent ponds and still-water zones of slow flowing creeks. It is characterized by a paired vocal sac and a bulbous thumb, considerably widened at the base. It is distinguished from P. minutus by its different call, body coloration, rounded snout, and a more robust body with shorter hindlimbs. Advertisement call, tadpole, and life history are described. The taxonomy of the family Pseudidae in Rio Grande do Sul is discussed, supporting the synonymy of Lysapsus mantidactylus and P. meridionalis with P. minutus.

The Resthenini genus Opistheurista has been known until now by the single species O. clandestina, which occurs in the Nearctic region. While studying mirids from Rio Grande do Sul, Brazil, we found a female exemplar as a new species. We provide descriptions, diagnoses, illustrations, and a key to distinguish the two species of genus Opistheurista.

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).
