| ABSTRACT Seeds can absorb N from mineral supplementation, thus stimulating seedling development in soybeans (Glycine max (L.) Merrill). This study aimed to evaluate the contribution to soybean seedlings of N derived from mineral supplementation in seeds with different nutritional contents. Seeds of the cultivar BMX Potência RR received mineral supplementation enriched with 2.5% excess 15N. The treatments were performed in seeds in two lots, one with high and one with low nutritional content. At 2, 6 and 10 days after sowing on paper towels, the seedlings were collected and separated into cotyledons, roots and shoots. Dry matter production, root length and root volume were assessed. Total N and 15N values were analyzed in the seedling organ tissues. The... |

| Species of Corallimorpharia collected during the CANCAP expeditions in the south-eastern part of the North Atlantic are described and discussed, altogether five species belonging to three genera of Corallimorphidae: the shallow water forms Corynactis viridis Allman, 1846, Pseudocorynactis caribbeorum den Hartog, 1980, and P. caboverdensis spec. nov., and the deep-sea forms Corallimorphus cf. atlanticus Carlgren, 1934, and C. ingens Gravier, 1918. The taxonomic status of the representatives of the genus Corynactis Allman, 1846, is discussed. All temperate to subtropical species described so far belong to a group of closely related allopatric taxa forming the Corynactis viridis-complex, possibly representing a single species only. The colours of Corynactis... |

| Mosquito fauna (Culicidae) from remote areas along the geographical limits of the State of Amazonas were assessed by employing CDC, Shannon, Malaise and Suspended traps, together with net sweeping and immature collections. Two hundred and six collections were performed in seven localities along the Nhamundá and Abacaxis Rivers, State of Amazonas, Brazil, during May and June 2008. The northernmost locality was 120 km from Nhamundá, whereas the southernmost locality was 150 km from the mouth of the Abacaxis River. The 5,290 mosquitoes collected are distributed in 16 genera, representing 109 different species, of which eight are new distributional records for the State of Amazonas. Furthermore, there are nine morphospecies which may represent undescribed new... |

| With 312 trap-hours of sampling effort, 1554 specimens of Culicidae (Diptera) were collected, using CDC and Malaise traps, in nine different locations along the Juami River, within the Juami-Japurá Ecological Station, Amazonas State, Brazil. A list of mosquito species with 54 taxa is presented, which includes three new distributional records for the state of Amazonas. The species found belong to the genera Anopheles, Aedeomyia, Aedes, Psorophora, Culex, Coquillettidia, Sabethes, Wyeomyia and Uranotaenia. |

| The recently described fish species, Astyanax altiparanae (tetra) is common in the upper rio Paraná basin, and has been reported in the Iguaçu basin. However, its natural origin in the rio Iguaçu is questionable. In the present work, karyotypical and morphological features of two populations of Astyanax altiparanae from the upper rio Tibagi and upper rio Iguaçu were compared. Both populations showed 2n=50 chromosomes and differences in their karyotype formula, NOR-bearing chromosomes and location of heterochromatin. Morphometric data from both populations were analyzed through free-size canonical variables. Cytogenetic and morphological results were mostly coincident showing exclusive markers that reflect their degree of populational isolation. In addition... |

| Wolfniana viridis sp. nov. is described and illustrated based on specimens collected in the municipality of Ipixuna (along Liberdade and Gregório rivers), state of Amazonas, Brazil. The new species can be distinguished from the type-species, W. limbatula (Osborn, 1926), by the color pattern which lacks conspicuous orange markings on head, pronotum, and forewing commissure; and aedeagal shaft with apex broadly expanded. Based on specimens of Rotigonalia concedula Melichar, 1926 and R. curvula Cavichioli, 2000, collected along with W. viridis, Rotigonalia Young, 1977 is firstly recorded from the state of Amazonas and R. concedula is firstly recorded from Brazil. |

| The rupicola series was proposed initially for Evandromyia rupicola (Martins et al) and Evandromyia correalimai (Martins et al), and recently extended with the inclusion of Evandromyia gaucha Andrade-Filho et al and Evandromyia grimaldii Andrade-Filho et al. The female of E. rupicola is here described and illustrated for the first time and its male is redescribed and drawn on the basis of specimens captured in forest on the coast of the state of São Paulo, Brazil. The head and genitalia of both sexes of E. correalimai are also illustrated. The distinctive traits among females of the four species and of males of E. rupicola, E. correalimai and E. grimaldii, and the distribution range of these species are commented. |

| The male of Mangora brokopondo Levi, 2007 is described and illustrated for the first time. Variation in the color pattern of the females is documented. Mangora woytkowskii Levi, 2007 is considered a junior synonym of M. hirtipes (Taczanowski, 1878). New records of M. alinahui Levi, 2007 and M. pia Chamberlin & Ivie, 1936 are presented. |
