| Um levantamento da fauna de formigas em uma área de mata nativa e em três plantações de Eucalyptus de 6, 20 e 106 meses de idade foi conduzido em agosto de 1992. Aamostragem consistiu de 2 transectos de 100 m por área, sendo que ao longo de cada transecto foram dispostas 10 armadilhas pitfall, que permaneceram no campo por 7 dias, após o que, foram substituídas por armadilhas contendo iscas de bolacha, sardinha e açúcar, que permaneceram na área por 1 hora para coleta das formigas. Além disso, para cada área foram feitas coletas manuais sobre o solo, senapilheira, árvores e arbustos por 5 horas não consecutivas.Um total de 121 morfoespécies, distribuídas em 5 subfamílias e 50 gêneros foram coletados. Os índices de Hill calculados indicam que na mata nativa... |

| We describe a new species of Oxyepoecus Santschi, 1926, Oxyepoecus regularis sp. nov., based on workers and a gyne collected in "Caatinga Arbórea" (Arboreal Shrubland) in Milagres and "Mata Seca" (Dry Forest) in Boa Vista do Tupim, both in the state of Bahia, Brazil. The gyne of Oxyepoecus browni Albuquerque & Brandão, 2004, collected in the same leaf litter ant survey, is also described. In addition, we present new records for Oxyepoecus species in Northeastern Brazil. |

| In the first paper of this series (Albuquerque & Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii group species and revise the other Oxyepoecus species-group (Rastratus). We describe two species (Oxyepoecus myops n. sp. and O. rosai n. sp.) and redescribe previously known species of the group [O. daguerrei (Santschi, 1933), O. mandibularis (Emery, 1913), O. plaumanni Kempf, 1974, O. rastratus Mayr, 1887, and O. reticulatus Kempf, 1974], adding locality records and comments on the meagre biological data of these species. We also present an identification key to Oxyepoecus species based on workers. |

| In Amazonia, topographical variations in soil and forest structure within "terra-firme" ecosystems are important factors correlated with terrestrial invertebrates' distribution. The objective of this work was to assess the effects of soil clay content and slope on ant species distribution over a 25 km² grid covering the natural topographic continuum. Using three complementary sampling methods (sardine baits, pitfall traps and litter samples extracted in Winkler sacks), 300 subsamples of each method were taken in 30 plots distributed over a wet tropical forest in the Ducke Reserve (Manaus, AM, Brazil). An amount of 26,814 individuals from 11 subfamilies, 54 genera, 85 species and 152 morphospecies was recorded (Pheidole represented 37% of all... |

| Ant species (Hymenoptera, Formicidae) from the seasonally dry tropical forest of northeastern Brazil: a compilation from field surveys in Bahia and literature records. The Caatingas occur predominantly in northeastern Brazil and comparatively it is the biome that received less attention than any other ecosystem in Brazil, representing the region where invertebrate groups are less known. We present here the first list of ant species of the Caatingas, compiling information from the literature, from a study of samples preserved in alcohol in the Laboratory of Entomology (Universidade Estadual de Feira de Santana), and from a field survey conducted in Milagres, Bahia, submitting standardized 1-m² samples of the leaf-litter to Winkler extractors. Summing all... |

| Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Enterococcus faecalis and Staphylococcus aureus) bacteria. Sterile filter paper was soaked with C. distans, C. pygmaea or C. rochai crude venom and placed on an agar dish that was inoculated with bacterial suspensions. The agar dish was incubated overnight at 37ºC and examined for zones of growth inhibition. For each tested venom and... |

| The use of arthropods for monitoring habitat changes has grown widely in the last decades. In Brazil, however, most of the studies in restored areas have involved only vegetation changes. The present study aimed at investigating recolonization patterns of epigeic arthropods in recently restored sites of semideciduous forests in southeastern Brazil. We compared the community structure of adjoining sites 5, 17, 29 and 36 months old with that at a nearby forest remnant (reference site). We also determined the most abundant species and looked for ecological indicator species of each site age. Arthropods were sampled using pitfall traps, and their assemblages were described and compared with multi- and univariate statistical methods. Species abundance and... |

| Os manguezais são comuns ao longo dos estuários da costa Atlântica do Brasil. Embora a diversidade de plantas seja baixa, esse ecossistema suporta uma fauna diversa, oferecendo diferentes tipos de recursos para numerosos organismos não aquáticos. Muitos insetos habitam as áreas de manguezal e, entre estes, numerosas espécies de formigas exclusivamente arbóreas. Na maior parte das áreas do mundo onde ocorrem, os manguezais vêm sofrendo altos níveis de impacto humano e isso é particularmente evidente no Sudeste da Bahia, onde ocorre o tradicional extrativismo de caranguejos e peixes, aterramento com fim de exploração imobiliária e corte de lenha. A comunidade de formigas de 13 manguezais com diferentes níveis de antropização foi estudada na costa sudeste da... |

| Leaves of copperleaf (Acalypha spp.) are greatly accepted by leaf-cutting ants and therefore used to maintain colonies in the laboratory. In order to determine the attractive potential of granulated bait of Acalypha wilkesiana leaves versus citrus pulp, currently used in commercial baits, an evaluation was performed, by using the leaf-cutting ant Atta sexdens rubropilosa as model. The handmade non-toxic baits contained powder (90% w/w) of either citrus pulp or A. wilkesiana were offered simultaneously in the foraging arena until the total loading of one of them. Results showed that copperleaf baits are less attractive than the citrus ones, which invalidates the viability of the substitution. |

| The genus Pachycondyla is a large group of ants in the Ponerini tribe, known mostly from tropical and subtropical regions. Pachycondyla sennaarensis, the so-called Samsum ant in the Middle East, is distributed throughout the African tropics, Arabian Peninsula and Iran, where it is responsible for many cases of insect-induced dermal lesions and systemic reactions in humans. Populations of P. sennaarensis were studied in two regions of Iran and some aspects of their biology, ecology and medical importance are herein presented. Colonies of P. sennaarensis contain less than 850 workers that live in complicated underground galleries approximately one meter deep. Because of the harsh weather conditions of southern Iran, they can survive only in human disturbed... |

| On Chichijima, one of the Ogasawara (Bonin) Islands located in the Western Pacific Ocean, land snails have declined, the suggested cause being predation pressure by an invasive flatworm (Platydemus manokwari). Soil fauna were investigated in areas where the snail survives, and where it has become extinct. Much of the fauna, dominated by introduced earthworms and ants, was undiminished, however, one undescribed but endemic carabid (Badister sp.), which selectively feeds on land snails, was absent in snail-extinct areas. The invasive flatworm P. manokwari has been reported to feed also on the carcasses of earthworms, as well as on live snails, and is therefore expected to occur in most parts of Chichijima Island. Among other groups, the density of isopods... |

| Três indivíduos da palmeira Attalea phalerata Mart (Arecaceae) foram amostrados 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 diversidade, hábitos alimentares e a distribuição espacial da comunidade de Formicidae em copas dessa palmeira que forma adensamentos monodominantes, típicos nessa região. Cada palmeira foi nebulizada uma única vez e realizadas três coletas subseqüentes. Um total de 966 formigas, pertencentes a 6 subfamílias, 13 tribos e 29 espécies foram amostradas em 49 m² de área amostral (19,7±52,7 indivíduos/m²) representando 3,9% do total de artrópodes obtidos. Myrmicinae foi a subfamília mais representativa, com... |
