| The female of Zimiromus hortenciae Buckup & Brescovit, 1993 is described for the first time and Trachyzelotes kulczynskii (Bösemberg, 1902), a species introduced from Europe, is recorded for the first time on the island of Fernando de Noronha, state of Pernambuco. The latter, along with T. lyonneti (Audouim, 1826) recorded from the state of Rio Grande do Sul, is the second species of this genus to be reported from Brazil. The spiders were collected with pitfall traps in five points of the island. Ecological data showed that Gnaphosidae was the fifth best sampled spider family, with 179 specimens, belonging to two species, T. kulczynskii and Z. hortenciae. Trachyzelotes kulczynskii was the most abundant with 118 adults while Z. hortenciae was... |

| The Parsimony Analysis of Endemicity (PAE) consists in an important tool of the historical biogeography which has the purpose of detecting distribution patterns of organisms and the relationships among areas of endemism. Insect distribution data included in Membracidae-Hoplophorionini occurring in the American Continent were used in the present research in order to establish the relationships among eight predetermined areas of endemism which are: 1) Mexico, 2) Greater Antilles, 3) Central America, 4) North Andes, 5) Central Andes, 6) South Andes, 7) Amazon, e 8) South East Brazil. The data matrix was based on the presence (coded as 1) and abscence (0) of taxa in the areas. The analysis was performed with the use of computer program Hennig86 (Farris 1988)... |

| Pseudothelphusidae is a well diversified group of Neotropical freshwater crabs currently comprising 40 genera and at least 255 species and subspecies. The biology of these crabs has been an active field of research in the last 20 years. The aim of the present contribution is to discuss the significance of the new knowledge on the biology of these freshwater crabs after September 1992, to stress the interconnection of the diverse lines of research and at the same time to suggest promising new lines of investigation. All taxa described from September 1992 to October 2004 are listed, including one genus, one subgenus, 62 species and five subspecies. The implications of this new knowledge on the taxonomy, systematic and biogeography of the family are commented. |

| Temnocephala lutzi Monticelli, 1913, ectosymbiont on brachyuran freshwater crabs of the genus Trichodactylus Latreille, 1828 is recorded for the first time in the State of Rio Grande do Sul, southern Brazil. Two hundred and seventy-nine crabs of two species were examined: 211 Trichodactylus panoplus (von Martens, 1869) and 68 Trichodactylus fluviatilis Latreille, 1828 of which 51 (24.17%) and 28 (41.17%) were positive for T. lutzi, respectively. Crabs of both species carried eggs fixed, exclusively, on the floor of the branchial chambers and/or on the lower side of the gills. Adult as well as young specimens were found inside and outside the branchial chambers. The temnocephalans were always devoid of body pigmentation, although they kept the red eye... |

| The following species is excluded from the neotropical fauna: Hesperia yva Plötz, 1886, mentioned by EVANS (1955) as Mucia yva, is an Asian species, probably a synonym of Suastus gremius (Fabricius, 1798). The following species are transferred to the neotropical region: Aurina dida EVANS, 1939, described from Sierra Leoa, Africa, and Hesperia subviridis Plötz, 1886, a species of Penicula EVANS, 1955, described from São Paulo, Brazil, was erroneously transferred by EVANS (1957) to Ceylon (=Sri Lanka). The types species of two genera are changed: Hydraenomia aberrans Draudt, 1924 is the new type of Clito EVANS, 1953, and Cantha calva EVANS, 1955 is the new type of Cantha EVANS, 1955 (ICZN, Art.70.3.2.). Popilio clito Fabricius, 1787, designated by... |

| Four species of scorpions (Ananteris mauryi Lourenço, 1982, Tityus neglectus Mello-Leitão, 1932, T. pusillus Pocock, 1893 and T. stigmurus (Thorell, 1876)) were collected in the " Mata do Buraquinho" , João Pessoa, state of Paraíba, Brazil. Aspects of biology for A. mauryi and new records on the geographic distribution of other species were annotated. Notes on the abundance and sex ratio on A. mauryi, the most abundant species in the area, are presented and discussed. |

| Abstract: Despite being the largest and most remarkable species of Chalcidoidea, species of Leptofoeninae are very rarely collected. Here, we expand the distribution range extension of the Leptofoenus howardi (Ashmead, 1895) for Rondônia and Minas Gerais, Leptofoenus stephanoides (Roman, 1920) for Rondônia, Espírito Santo and São Paulo and Leptofoenus westwoodi (Ashmead, 1895) for Roraima, Amazonas, Rondônia, Bahia, Minas Gerais, Rio de Janeiro and Rio Grande do Sul. |

| ABSTRACT The present study describes Tereancistrum flabellum n. sp. (Dactylogyridae, Ancyrocephalinae) from the gills of the anostomid fishes Leporinus friderici, Leporinus amblyrhynchus and Leporinus elongatus from two freshwater ecosystems in the south east of Brazil. This new species is mainly characterized by the morphology of the copulatory complex (such as the MCO base formed by two fan-shaped structures, and accessory piece flattened, curved, rigid and channeled), a dorsal anchor with a well-developed superficial and inconspicuous deep root, and the shape of the accessory anchor sclerite with small spathulate termination. Tereancistrum flabellum n. sp. is the first record of a dactylogyrid from L. amblyrhynchus. The description of Tereancistrum... |

| Brazil has a high diversity of flies of the genusDrosophila, and part of this richness is represented by thecardini group. We analyzed the fluctuations in the richness and abundance of this group, in environments that had never previously been studied in the northeastern region of Brazil. Among the 28,204 drosophilids sampled, 1,294 belonged to the cardini group and were represented by D. polymorpha, D. cardini, D. neocardini and D. cardinoides. Occurrences ofD. neocardini and D. cardinoides were registered for the first time in the Caatinga. In this biome,D. cardini stood out as having the highest abundance, andD. polymorpha was not observed. In the coastal Atlantic Forest, D. cardini was not registered, but D. polymorpha was found in all the localities... |

| In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 taxa. Our results show that macroinvertebrate communities, at genus as well as family level, are in concordance to a priori classifications that distinguish between white and clear water streams. The main implication of our results for biomonitoring... |
