A New Species

A new species of the loricariid subfamily Neoplecostominae is described on the basis of specimens obtained from the headwaters of the rio Iguaçu basin in the State of Paraná, southern Brazil. Pareiorhaphis parmula is the first representative of the genus discovered from the rio Paraná basin and expands the geographic distribution of the genus. It is diagnosed from other Pareiorhaphis species by having one small plate on each side of the pectoral girdle, just posterior to the gill opening and the club-shaped pectoral-fin spine, broadening from base to tip in adult males. All species formerly included in Hemipsilichthys except H. gobio, H. papillatus, and H. nimius are transferred to the genus Pareiorhaphis, which is resurrected from the synonymy of Hemipsilichthys.

The Brazilian records on Xenacanthiformes include teeth and cephalic spines from the Parnaíba, Amazonas and Paraná basins. This work describes a new species of Xenacanthidae, collected in an outcrop of Serrinha Member of Rio do Rasto Formation (Wordian to Wuchiapingian), Paraná Basin, municipality of Jacarezinho, State of Paraná. The teeth of the new species are two or three-cuspidated and the aboral surface show a smooth concavity and one rounded basal tubercle. The coronal surface presents one semi-spherical and subcircular coronal button, and also two lateral main cusps and one central (when present) with less than one fifth of the size of the lateral cusps in the labial portion. The lateral cusps are asymmetric or symmetric, rounded in transversal section, lanceolate in longitudinal section, devoid of lateral carinae and lateral serrations, and with few smooth cristae of enameloid. In optical microscope the teeth show a trabecular dentine (osteodentine) base, while the cusps are composed by orthodentine, and the pulp cavities are non-obliterated by trabecular dentine. The fossil assemblage in the same stratigraphical level and in the whole Rio do Rasto Formation indicates another freshwater record for xenacanthid sharks.

(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.

Pherania giupponii sp. nov. is herein described from a coastal island in Santa Catarina state, southern Brazil. The genus Pherania Strand, 1942, was hitherto monotypic and the type species, Pherania pygmaea (Sørensen, 1932), is known from the nearby mainland.

ABSTRACT A new species of Characidium is described based on specimens obtained from the highland streams of the Serra do Mar, Atlantic Forest Biome, in Paraná State, Southern Brazil. The new species is possibly a member member of the C. lauroi group, which is diagnosed by having the isthmus unscaled, bars poorly marked, and spots on sides of body, and is composed by four additional species: C. japuhybense ; C. lauroi ; C. oiticicai ; and C. schubarti . The new species differs from its congeners with naked isthmus, except C. helmeri , by having 15-18 principal caudal-fin rays; and 10-12 pectoral-fin rays; and from C. helmeri , by having a slender body, tip of pectoral fin not reaching origin of pelvic fin, tip of pelvic fin not reaching beyond anus, supraorbital present and well developed, and by lacking vertically elongated dashes on sides of body. The new species is known from tributaries of the rio Jordão, in the rio Iguaçu Basin, and rio Taquari, a tributary of the rio Ribeira de Iguape coastal drainage.

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).

A revisional taxonomic study of Adesmia subg. Adesmia ser. Bicolores has unveiled a new species from southern Brazil. Adesmia miottoae is described and illustrated here. Its geographic distribution, phenology, conservation status and morphological similarities with its closest relatives, Adesmia punctata and A. incana, are presented. The species is distinguished by glandular trichomes covering all the aerial parts of the plant, except the corolla. These trichomes are shorter than those of Adesmia punctata. Additionally, a detailed anatomical description of the leaflet blade is provided.

A New Species

Jenynsia tucumana new species is described from the upper Río Salí basin, province of Tucumán, northwestern Argentina. The new species is diagnosed by the possession of a row of dark markings ranging from dots to small vertical stripes from the tip of adpressed pectoral fin to the posterior margin of the hypural. Also, the new species has a mandibular canal pore W and a symmetrical fifth anal-fin ray in adult males; whereas the females lack a urogenital swelling. According to a phylogenetic reanalysis of the genus, the new species is sister to most species of the subgenus Jenynsia, except for J. onca and possibly J. sanctaecatarinae.
