| Gavarilla gen. nov. from Northeastern Brazil is proposed to include two new species: the type species Gavarilla ianuzziae sp. nov. from the State of Sergipe and Gavarilla arretada sp. nov. from the State of Maranhão. The genus presents the standard sitticine dentition and is presumably related to the genera Aillutticus Galiano, 1987, Nosferattus Ruiz & Brescovit, 2005, Capeta Ruiz & Brescovit, 2005 and Amatorculus Ruiz & Brescovit, 2005, with which it shares the similar high, rounded carapace. Two new species, Capeta cachimbo and Amatorculus cristinae, are also described from the State of Pará, and Amatorculus stygius Ruiz & Brescovit, 2005 is recorded for the first time from the State of Minas Gerais. |

| Based on field data, this study presents the growth curve of Balloniscus glaber Araujo & Zardo, 1995, a terrestrial isopod species found in Parque Estadual de Itapuã (PEI), Rio Grande do Sul, Brazil. Specimens were monthly sampled, from May 2004 to April 2005, at PEI. Captured individuals were sexed, their cephalothorax width was measured, and the growth curve was described according to von Bertalanffy's model. Male and female growth curves are described by the equations: Wt = 2.256[1-e-0.00394(t+91.128)] and Wt = 2.588[1-e-0.00301(t+101)], respectively. Curves show differential growth between males and females, with females reaching higher W<FONT FACE=Symbol>¥</FONT>, and a slower growth rate than males. Based on theses curves, life... |

| ABSTRACT The State of Acre, in the southwestern Brazilian Amazon, harbors high biodiversity and a high degree of endemisms. Nevertheless, there are few studies on the diversity of social wasps occurring in this region. This study presents a list of social wasps (Hymenoptera, Vespidae, Polistinae) collected actively with attractive bait in three rainforest fragments in Acre. A total of 758 wasps belonging to 11 genera and 36 species were collected. Nineteen species were new distribution records for Acre and three others were new records for Brazil. Based on our results, further investigations should lead to a significant increase in Polistinae diversity in this region, producing information for biogeographic studies and management of natural areas. |

| Abstract: The regional knowledge of species diversity and distribution is important to support conservation strategies for species and their habitats. The main goal of this work is to present a checklist of Odonata species in the state of Rio Grande do Sul, as well as their known locations in the municipalities. The preparation of the list was based in data gathered from collections of Museu de Ciências da Universidade do Vale do Taquari (UNIVATES), Laboratório de Ecologia e Evolução da Universidade do Vale do Taquari (UNIVATES), Museu de Ciências Naturais da Fundação Zoootânica, Museu de Zoologia da Universidade do Vale do Rio dos Sinos (UNISINOS) plus data extracted from 65 publications and the sites SpeciesLink, All Odonata and Puget Sound University.

| Land flatworms show high endemism due to their restricted mobility. In southern Brazil, land flatworm communities have been found mainly in areas of ombrophilous forests. Thus, this study documents land planarian species composition in remnants of deciduous seasonal forest in the northeast region of southern Brazil. Direct, diurnal samplings reveal the occurrence of 26 species of land flatworms, of which one belongs to the subfamily Rhynchodeminae and the others to the subfamily Geoplaninae. The Rhynchodeminae genus Rhynchodemus Leidy 1851 and the following Geoplaninae genera occurred: CephaloflexaCarbayo & Leal-Zanchet, 2003, Choeradoplana Graff, 1896, Imbira Carbayo et al., 2013, IssocaFroehlich, 1955, LuteostriataCarbayo, 2010, Obama Carbayo et al.,... |

| Abstract: Freshwater ichthyofauna from Brazil Northeast region was considered as being poorly known until recent years, with a considerable number of publications becoming available in the last decade. The present study provides an inventory of freshwater fish species from the Paraíba do Norte River basin located in Paraíba State, Brazil. This inventory is intended to contribute to the of knowledge to the regional fish diversity, pre-transposition of the São Francisco River. Collecting data was obtained from ichthyological databases of both national and foreign institutions. A total of 47 freshwater fish species are registered within the Paraíba do Norte River basin, represented by 38 genera, 20 families and six orders. Characiformes, comprising 47% (22... |

| Abstract Treehopper assemblages were sampled in four semi-arid areas of caatinga in Northeast Brazil during the rainy seasons of 2016 and 2017, using three different capture methods. The areas are located in two Ecoregions of the Caatinga: “Depressão Sertaneja Setentrional” (Northern Sertaneja Depression) and “Planalto da Borborema” (Borborema Plateau). A total of 2,394 individuals of 43 species were sampled, corresponding to approximately 87% of the mean estimated species richness for all four areas. The species richness varied among the areas from 14 to 21, while the abundance of individuals ranged from 129 to 1860. Eighteen species were shared among areas, of which only Enchenopa eunicea, Sundarion sp. 1, Ceresa vitulus and Erosne parvula occurred in... |

| Abstract: The Mamanguape River Basin is located in a peripheral semi-arid area of South America, with its headwaters and middle reaches running through the Caatinga (from wetter to drier) and its lower reaches through the Atlantic Forest. The objective of this study was to inventory the fish fauna of the Mamanguape river basin through a comprehensive sampling and to discuss its ichthyofaunal dominance pattern. Sampling was conducted between 2015 and 2016 at 38 points throughout. The main river course was sampled at 18 fixed points during two expeditions (dry and wet seasons) using traw nets, cast nets, and dip nets, with a standardized effort. The tributaries were sampled during the dry season at 20 points using an adaptaptation of the AquaRAP methodology.... |

| Abstract Humid highland forest enclaves are remnants of Atlantic Forest found in tablelands within the Caatinga biome (Northeastern Brazil), which emerged during interglacial periods in the Pleistocene. These ecosystems have a highly diverse and endemic fish fauna. Most earlier surveys have focused on the tableland of Borborema (Pernambuco and Paraíba States). In this study we surveyed the fish fauna of the humid forest enclaves in the tablelands of Ibiapaba and Araripe, based on samples collected in the rainy season (March and April) between 2009 and 2014. The 45 sampling points covered rivers, streams and reservoirs in five river basins belonging to three ecoregions. The species were listed according to drainage divide, and endemism was determined for... |

| Abstract: The principal aim was to assess the environmental perception of the fishermen, and implement educational activities, on an island in Brazil. Twelve people between the ages of 23 and 63 were interviewed, of whom 75% were male, and 58.33% did not complete their elementary education. Regarding social benefits, 33.33% receive a family allowance and 16.66% receive the so-called 'green allowance' (financial assistance to extremely poor families who live in areas of environmental preservation). Fishing remains the main economic activity (58.73%). The most common types of fishing gear are the 'zangarias' (41.66%) and 'muruadas' (41.66%), used to catch white shrimp (Litopenaeus schmitti), the main resource traded on the island (83.33%). All those... |

| Male Neotropical orchid bees (Euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. The ultimate causes of euglossine fragrance collection remain a mystery. Recent evidence suggests that odoriferous substances play a role in euglossine courtship and serve as indicator of male genetic quality. Males of Eulaema nigrita were observed robbing scents from the detached hind legs of a conspecific male E. nigrita in Belém, Brazil. The hind leg seemed to have been detached during fights between males, since one male was missing a hind leg where the observation was made. This behavior appears to be common among males of E. nigrita since more than one case was observed on the same day. The... |
