| A new genus of spittlebug is described to include Gervasiella oakenshieldi sp. nov. (holotype male from Brazil, state of Paraná, municipality of Piraquara, Mananciais da Serra at 25°29'46"S, 48°58'54"W, 1000 m a.s.l., 15.XI.2008, P.C. Grossi leg., deposited in DZUP). In addition, Aeneolamia bucca Paladini & Cavichioli, 2013 is transferred to Gervasiella gen. nov. based on the results of a cladistic analysis. Gervasiella gen. nov. can be distinguished from the other cercopid genera by the following: postclypeus inflated with upper portion black and basal one yellowish; color of tylus distinct from color of head and rostrum, barely reaching mesocoxae. Gervasiella oakenshieldi sp. nov. is diagnosed by having the head black with tylus white, postclypeus in... |

| The Neotropical sharpshooter Parasubrasaca felixi, gen. nov., sp. nov., is described and illustrated from the Atlantic Rainforest of Southeastern Brazil (state of Espírito Santo). The new genus can be distinguished from other members of the Cicadellini by several morphological features, including a unique modification of the basal portion of the aedeagus, which bears a conspicuous, ventrally directed projection that articulates with the connective. The projection bears a pair of strong spines directed posteriorly. In addition to the external morphology, color pattern, and male genitalia, the female genitalia of the new taxon are also described in detail. A discussion comparing the new genus with similar Neotropical taxa (Subrasaca Young, 1977, Soosiulus... |

| Fernandesia meridionalis Rodrigues & Maia, a new genus and species of Cecidomyiidae associated with Myrciaria delicatula O. Berg (Myrtaceae) is described and illustrated (male, female, pupa, and larva) based on material from Rio Grande do Sul, Brazil. The new genus belongs to Lasiopteridi, but it cannot be placed to tribe. A key to the tribes of Lasiopteridi and one to the unplaced genera of Neotropical Lasiopteridi are given. |

| ABSTRACT A new genus and species of gall midge, Haplopappusmyia gregaria, is described and illustrated (larva, pupa, male, and female). This species induces apical galls on Haplopappus foliosus (Asteraceae), an endemic shrub from central Chile. The specimens were collected at La Ligua Municipality, Petorca Province, Valparaiso region, Chile, during spring of 2011-2014. This area corresponds to one of the fifth Mediterranean Matorral biome, considered among Earth's biodiversity hotspots. The new genus is characterized by presenting lateral margin of antennal scape with a mesal reentrance; four-segmented palpus, one-toothed tarsal claws, R5 straight, reaching C anterior to wing apex; male seventh and eighth tergites lacking sclerotization mesally, beyond... |

| A new genus, Podkova, is described from Brazil to accommodate its type-species P. hirsuta, sp. n. The genus has a peculiar appearance, the main features of which are the small compact body with coarsely pilose dorsal parts of the head and mesosoma, including median part of propodeum, head with sharp frontal carina of horse-shoe shape, delimiting broad facial cavity with rather short antennae, and a sharp occipital carina stretching posteriorly down along hind margins of eyes. By these features, Podkova resembles the genus Alachua Schauff and Boucek, but differs distinctly by having strong frontal carina on the head and the prepectus hardly overlapped by the anterior margin of mesosternum. Possible affinities to some other entedonine genera are discussed. |

| ABSTRACT Rhyacoglanis, a new genus of the South American freshwater catfish family Pseudopimelodidae is described from cis-Andean portions of the continent. Rhyacoglanis is distinguished from other genera of the family by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. Species of Rhyacoglanis are rheophilic and strongly associated with rapids and other swift-flowing waters. A phylogenetic analysis based on 41 morphological characters yields a hypothesis of monophyly of the Pseudopimelodidae and Rhyacoglanis. Pimelodus pulcher Boulenger, 1887, from the western Amazon basin is designated as type-species of the new... |

| ABSTRACT Nungara gen. nov. is proposed to include the type species, Nungara niveomaculata (Mello-Leitão, 1941) comb. nov., transferred from Olios Walckenaer, 1837 and two new species, described from males and females: N. anama sp. nov., from the states of Sergipe, Alagoas and Espírito Santo, and N. gaturama sp. nov., from the states of Sergipe, Bahia and Espírito Santo, all in Brazil. The new genus is distinguished from all other Neotropical sparassid genera by the presence of a deep tegular groove on the male palpal bulb and a hood-like projection on the median septum of the female epigyne. In addition, Olios fuscovariatus Mello-Leitão, 1943, Stasina koluene Mello-Leitão, 1941 and Polybetes proximus Mello-Leitão, 1943 are transferred to Nungara gen. nov.... |

| Listrura costai, new species, is described from small streams in a swampy coastal plain in the rio Jurumirim basin, Angra dos Reis Municipality, Rio de Janeiro State, southeastern Brazil. The new species is morphologically very similar to L. nematopteryx and L. picinguabae, all possessing only one long pectoral-fin ray. It differs from its congeners by possessing an autapomorphic character: first hypobranchial with an anterior process (vs. process absent). Other features such as coloration, numbers of opercular and interopercular odontodes, number of anal-fin rays, head length, and shape of some bone structures help to distinguish the new species from L. nematopteryx and L. picinguabae. Molecular analyses using partial sequences of the mitochondrial DNA... |

| ABSTRACT A new species of the lizard genus Stenocercus Duméril & Bibron, 1837 is described based on six specimens from Serra da Canastra, Minas Gerais, southeastern Brazil. Similar to S. tricristatus (Duméril, 1851), S. dumerilii (Steindachner, 1867), S. quinarius Nogueira & Rodrigues, 2006, and S. squarrosus Nogueira & Rodrigues, 2006, the new species has a pyramidal head and an enlarged, dorsally projected post-supraciliary scale, like a small horn. It is most similar to S. tricristatus, from which it differs in having a more elongated head in ventral view; a larger number of scales around midbody; a distinctly enlarged, smooth preauricular scale; and probably a larger body size. Moreover, the new species has distinctly keeled scales, with... |
