| Linyphiidae is currently the second richest family of spiders in the order Araneae but is poorly known and studied in Brazil, particularly in the northern states. In this contribution we describe a new species of Exechopsis Millidge, 1991 from the State of Amazonas, based on both males and females. The male of Meionetaadami Millidge, 1991 is described for the first time. Mermessus conjunctus (Millidge, 1991), Novafrontina uncata (F. O. Pickard-Cambridge, 1902), Sphecozone fastibilis (Keyserling, 1886), Sphecozone ignigena (Keyserling, 1886) and Vesicapalpus simplex Millidge, 1991 are recorded for the first time from Amazonas. Sphecozone crassa (Millidge, 1991) are presented additional record from Amazonas. |

| Abstract A checklist of the family Chelodesmidae Cook, 1895 (order Polydesmida) from state of São Paulo, Brazil has been performed based on literature and examined material from the collection of the Instituto Butantan, São Paulo (IBSP). A total of 15 genera (7 tribes and 5 genera considered incertae sedis) with 64 species are listed. Among these species, 30 presented a single one record in the state, 19 with more than one record and four recorded for the first time for the state of São Paulo, and 11 species occurring in other Brazilian states. The most distributed species is Brasilodesmus paulistus paulistus (Brölemann, 1902) with 52 records of occurrence. In addition, a complete bibliography list of the chelodesmidan fauna from the state is compiled, as... |

| Para avaliar quais as aranhas sinantrópicas de Salvador e relacionar a sua distribuição com a estrutura física das residências, e a composição das espécies com o tempo de ocupação urbana, investigou-se 3 bairros escolhidos segundo sua idade aproximada: Santo Antônio Além do Carmo (300-400 anos), Itapuã (100-300) e Pituba (menos de 50). A base amostral para residências correspondeu a 10% do setor censitário, com 6 capturadores realizando entrevistas concomitantes às capturas, nos domicílios e peridomicílios. Foram coletados 677 aranhas, 329 adultos, identificados em 13 espécies e 17 morfoespécies, distribuídas em 10 famílias, de novembro 2002 a junho 2003, num esforço amostral de 30 minutos/domicílio (n=71) ou peridomicílio. Pholcidae (n=256), Oecobiidae... |

| Seis palmeiras de Attalea phalerata foram amostradas durante a fase aquática (cheia) no Pantanal de Mato Grosso (fevereiro/2001), utilizando-se a metodologia de nebulização de copas "canopy fogging". Este estudo objetivou avaliar a composição, distribuição espacial, guildas comportamentais, biomassa e sazonalidade da comunidade de Araneae em copas dessa palmeira que forma adensamentos monodominantes, típicos nessa região. Um total de 1326 aranhas foram coletadas em 99 m² de área amostral (13,4 + 8,2 indivíduos/m²), representando 20 famílias, sendo Salticidae e Araneidae as mais abundantes. A biomassa total de 704 aranhas em três palmeiras correspondeu a 0.6172 mg de peso seco (0,0123+ 0,04 mg/m²). Dez guildas comportamentais demonstraram a coexistência de... |

| Theridiidae is a derived family within the Araneoidea clade. In contrast to closely related groups, the 2n(male) = 20+X1X2 with acro/telocentric chromosomes is the most widespread karyotype among the theridiid spiders. In this work, the cytogenetic analysis of Argyrodes elevatus revealed original chromosome features different from those previously registered for Theridiidae, including the presence of 2n(male) = 20+X with meta/submetacentric chromosomes. Most individuals of Nesticodes rufipes showed family conserved karyotype characteristics. However, one individual had a 2n(male) = 24 due to the presence of an extra chromosome pair, which exhibited regular behavior and reductional segregation during meiosis. After silver staining, mitotic cells exhibited... |

| Este estudo teve como objetivo avaliar a composição da comunidade edáfica de Araneae de uma floresta sazonalmente inundável na região norte do Pantanal de Mato Grosso, tendo como base sua densidade de atividade e emergência. Foram empregadas armadilhas de solo tipo pitfall-trap para avaliação da atividade sobre o solo, e fotoecletores de solo para verificar a densidade de emergência ao longo de todos os períodos sazonais desta região, entre janeiro de 2004 e janeiro de 2005. Como resultado obteve-se um total de 2.233 aranhas, 1.314 indivíduos obtidos com armadilhas pitfall (29 famílias e 35 gêneros) e 919 com fotoecletores de solo (27 famílias e 22 gêneros). Oonopidae (335 ind.: 15,0%), Corinnidae (310 ind.; 13,9%), Gnaphosidae (289 ind.; 12,9%) e Ctenidae... |

| Abstract: The ability of spiders to spread over contiguous areas (Arachnida: Araneae) is directly related to soil management conditions. The objective of this work was to study the effect of land use system (LUS) on the abundance and diversity of soil spider families and their relationship with soil physical and chemical properties. The evaluated LUS were: native forest, eucalyptus reforestation, pasture, crop-livestock integration, and no-tillage crop. Samples were collected in three municipalities of Southern Plateau of Santa Catarina, considered as true replicates, during winter and summer. A total of 270 samples was taken in each area and season. The sampling points were arranged in a grid of 3 × 3 m, spaced by 30 m. We evaluated soil physical,... |

| Aspects of the behavior of the theraphosid spider Pachistopelma rufonigrum, in two species of tank bromeliads in an area with white sands in the Serra de Itabaiana, Sergipe, Brazil, are described. Observations on habitat, microhabitat, foraging, ecdysis and reproduction, were made. Our data suggested that P. rufonigrum inhabits only these species of bromeliads, since all stages of the life cycle were observed in the plant. The relationships degrees between P. rufonigrum and the species of studied tank bromeliads are discussed. |

| The subfamily Anyphaeninae is revised at genera level in the Neotropical region. Anyphaeninae is diagnosed by the tracheal spiracle approximately in the midway of venter or between the midway of venter and the epigastric groove; retromargin of chelicerae with more than four denticles; and male palp with tegulum basket-like or cup-like, without the basal lightly sclerotized area. The subfamily contais 32 genera, 14 of which are new: Aljassa (type species Teudis annulipes Caporiacco), Buckupiella (type species B. imperatriz sp.n., from Brazil and Argentina), Hatitia (type species H.yhuaia sp.n., from Peru) Iguarima (type species Anyphaena censoria Keyserling), Ilocomba (type species I. marta sp.n., from Colombia), Italaman (type species I. santamarina sp.n.,... |

| The Brazilian Savanna Ecoregion (Cerrado) is one of the richest biomes in the world, with a characteristic highly seasonal climate a dry season between May and September and a rainy season from October through April. Ground-dwelling spiders from three Cerrado phytophysiognomies, "campo cerrado", "cerrado" and "cerradão", were sampled using pitfall traps during two years, totaling 111 species and 3,529 individuals. The abundance of individuals and species richness was higher during the wet season. Fifty-eight species were captured exclusively during that period, whereas only nineteen were restricted to the dry season. Only two species were found in all samples. The number of juveniles was higher than the number of adults in all phytophysiognomies and in all... |

| ABSTRACT: Spiders are part of the soil biodiversity, considered fundamental to the food chain hierarchy, directly and indirectly influencing several services in agricultural and forest ecosystems. The present study aimed to evaluate the biodiversity of soil spider families and identify which soil properties influence their presence, as well as proposing families as potential bioindicators. Native forest (NF) and reforested sites (RF) with Araucaria angustifolia (Bertol.) Kuntze were evaluated in three regions of the state São Paulo, both in the winter and summer. Fifteen soil samples were collected from each forest to evaluate the biological (spiders and microbiological), chemical and physical soil properties, in addition to properties of the litter (dry... |
