| The spider genus Berlandiella Mello-Leitão, 1929 is revised and the three known species, Berlandiella insignis Mello-Leitão, 1929 (Rio de Janeiro), B. magna Mello-Leitão, 1929 (Pernambuco, Minas Gerais, Rio Grande do Sul), and B. polyacantha Mello-Leitão, 1929 (Rio de Janeiro, São Paulo), are redescribed and illustrated. Lectotypes for Berlandiella insignis, B. magna and B. polyacantha are designated. Descriptions and illustrations of three new species are presented: B. robertae sp. nov. (Brazil and Argentina), B. meridionalis sp. nov. (Brazil) and B. querencia sp. nov. (Brazil). The geographical distribution of the representatives of the genus is presented. |

| Based on the types of Edessa rufomarginata (De Geer, 1773) and its synonyms, on morphology of the paramere and coloration, seven patterns are described for E. rufomarginata. Pentatoma furcata Palisot de Beauvois, 1805, Cimex cruentus Fabricius, 1775, Aceratodes flavovirens Stål, 1855 and A. flavomarginatus Stål, 1855 are mantained as junior synonyms of E. rufomarginata. A. albomarginatus Stål, 1855 and A. marginalis Dallas, 1951 are removed from the synonymy of E. rufomarginata and are reinstated in Edessa. Aceratodes discolor Dallas, 1951 is removed from the synonymy of E. rufomarginata and is considered junior synonym of Edessa abdominalis Erichson, 1848. |

| ABSTRACT Fish exhibit morphological, physiological and behavioral specializations which enable them to display different ways to explore the environments and resources. Thus, the aim of this study was to verify how four Auchenipteridae species differ in the distribution, feeding habits and morphological traits: Auchenipterichthys longimanus (Günther, 1864), Auchenipterus nuchalis (Spix & Agassiz, 1829), Tatia intermedia (Steindachner, 1877) and Trachelyopterus galeatus (Linnaeus, 1766). This study was conducted in rivers and bays of the Anapú Basin, Pará State (Brazil), where these species are abundant. Specimens were collected using gillnets, and after caught the stomachs were removed for the contents analyzes. Eighteen morphometric measurements from... |

| Calanoid copepods are abundant in South American inland waters and include widespread species, such as Boeckella gracilipes (Daday, 1902), which occurs from the Ecuador to Tierra del Fuego Island. This species occurs under various environmental conditions, and is found in oligotrophic lakes in Patagonia (39-54°S) and in shallow mountain lakes north of 39°S. The aim of the present study is to conduct a morphometric comparison of male specimens of B. titicacae collected in Titicaca and B. gracilipes collected in Riñihue lakes, with a third population of B. gracilipes collected in shallow ponds in Salar de Surire. Titicaca and Riñihue lakes are stable environments, whereas Salar de Surire is an extreme environment. These ponds present an extreme environment... |

| The present study is a further contribution to the systematic knowledge of the shallow water marine ostracodes from the Brazilian oceanic islands. A total of 14 species belonging to 10 genera and eight families is herein identified. One new genus and species are described and illustrated: Berguecythere insularis gen. nov., sp. nov. In addition to this new taxon, the abundant species Loxocorniculum tricornatum Krutak, 1971, widely distributed in recent sediments in the Gulf of Mexico, Caribbean, north and northeast of Brazil and the Rocas Atoll, along with the cosmopolitan tropical ostracode Triebelina sertata Triebel, 1948, were also identified at specific level. The remaining 11 species were left at the genus level, and should provide new species.... |

| To assess genetic structure and phenotypic diversity of Eupemphix nattereri Steindachner, 1863, morphometric and molecular analyses were carried out for nine populations from the State of Goiás. A total of 11 morphometric traits were evaluated and genetic information was estimated using RAPD markers. Genetic and phenotypic distances were determined as a function of geographical origin. Correlation among genetic, morphometric, micro, and macroenviromental were analyzed by the Mantel test. Genetic data indicated high levels of genetic diversity (Φst= 0.3) among the nine populations. Mantel tests did not reveal a significant positive correlation between genetic and geographical distances, indicating that locally geographical populations were not genetically... |

| Runibia Stål, 1861 is redescribed, as well as the species R. dallasi Rider, 1998, R. decorata (Dallas, 1851), R. discoidea (Fabricius, 1787), R. euopta (Walker, 1867) and R. perspicua (Fabricius, 1798). A new species, R. caribeana, is described from Virgin Islands. Strachia alligata Walker, 1867, R. decorata var. alligata, and R. picturata Breddin, 1904 were considered junior synonyms of R. decorata. Lectotypes of R. dallasi, R. euopta and R. alligata were designated. Male and female genitalia for all species are described, except the phallus and ectodermal genital duct for R. dallasi. A key and a geographical distribution map are also provided. |
