| We analyzed the effects of environmental factors on abundance, species richness, and functional group richness of Leptophlebiidae in 16 sampling points along four Cerrado streams. Across three periods of 2005, we collected 5,492 larvae from 14 species in stream bed substrate. These species belong to three functional feeding groups: scrapers, filtering collectors and shredders. The abundance and species richness were not affected by water quality, but habitat quality related to presence of riparian vegetation had positive effects on the abundance of shredders. Our results add important information on the natural history of the species and functional groups of aquatic insects and also provide relevant data for the monitoring and conservation of streams in... |

| ABSTRACT Trichoptera presents about 15,000 species described globally, of which 2,562 are recorded in the Neotropics and 642 in Brazil, distributed in 70 genera and 16 families. In Brazil, knowledge of the distribution and species richness of Trichoptera is incipient and heterogeneous, especially in some states such as Mato Grosso do Sul. In this work, we present an updated checklist of caddisflies for Mato Grosso do Sul state, representing nine families, 24 genera, and 16 species, four of them are new species records. Additionally, a new record of species for the Brazilian country is presented. |

| ABSTRACT Tropical streams feature high variety of habitats and environmental gradients, which reflect on the greater richness of aquatic insects. In this way, we evaluate if the diversity of aquatic insects of prey and predator categories is influenced by the type of substrates or by longitudinal portions in Cerrado streams. Our hypothesis is that prey and predator diversity will be determined by the type of substrate, assuming that the substrate serves as a source for foraging and / or refuge. In addition, the folhiço substrate will present greater abundance and richness due to the availability of shelter and food provided by this type of substrate. There will be differences in prey and predator composition among substrates, since some species have... |

| La distribución de los Triatominae de Colombia y su infestación con flagelados se presenta en forma de tablas. Rhodnius prolixus es el principal vector de Trypanosoma cruzi en Colombia y es abundante en la parte central y oriental del país. Rhodnius prolixus, Triatoma dimidiata y Triatoma venosa han sido colectados 20 veces en localidades de altura superior a los 2000 ms, y en 10 de esas localidades los insectos estaban infectados con Trypanosoma cruzi. Siete de las 15 especies colombianas conocidas de Traitominae son portadoras de flagelados y Triatoma venosa ha sido encontrado como un nuevo huésped para Trypanosoma cruzi. |

| ABSTRACT Organisms with complex life cycles typically do not exhibit parental care. Hence, the ability of adult females to choose quality oviposition sites is critical for offspring success. Gravid females of many insect taxa have the capability to detect environmental conditions in water-holding containers (e.g., resource level, presence of competitors or predators) and to choose the sites that are most suitable for offspring growth and development. Mosquitoes may also detect physical container characteristics related to water permanence such as surface area, volume, or container size, and some species such as those in the genus Culex have been shown to prefer larger containers. However, predators may also preferentially colonize larger containers; thus,... |

| Mosquitoes in the family Culicidae develop their immature forms in different environments depending on various circumstances. This study represents the first contribution to the ecological knowledge of culicids living in the bromeliad G. brasiliensis. The objectives of the study were to compare the Culicidae fauna of bromeliads in two seasonal periods, analyzing their abundance, richness and the influence of pH, conductivity and water volume, on the populations. Sampling was done at Reserva Adolpho Ducke, Manaus, Amazonas, Brazil between 2003 and 2005. Six samplings were done in the rainy season and six in the dry season. On each sampling day, six terrestrial and six epiphytic bromeliads, totaling 144 sampling units, were retrieved. A total of 444 immature... |

| ABSTRACTIn order to expand the knowledge on the composition of Ephemeroptera from large rivers, we present, herein, the first survey of mayflies from the São Mateus River Basin, Espírito Santo State. Adults were collected biannually in 2012 and 2013 with the aid of Pennsylvania light trap in eleven points distributed in the main river of the river basin, São Mateus River and its two main tributaries, Cotaxé River (Braço Norte) and Cricaré River (Braço Sul). Thirty-three species were identified (22 nominal and 11 morphospecies) in 24 genera and five families. One genus and one species are reported for the first time from Brazil, three species from Southeastern Region of Brazil, and two species from the state. Five species and one genus not previously... |

| ABSTRACT Biomass is a fundamental measure for understanding the structure and functioning (e.g. fluxes of energy and nutrients in the food chain) of aquatic ecosystems. We aim to provide predictive models to estimate the biomass of Triplectides egleri Sattler, 1963, in a stream in Central Amazonia, based on body and case dimensions. We used body length, head-capsule width, interocular distance and case length and width to derive biomass estimations. Linear, exponential and power regression models were used to assess the relationship between biomass and body or case dimensions. All regression models used in the biomass estimation of T. egleri were significant. The best fit between biomass and body or case dimensions was obtained using the power model,... |

| Diversity of Odonata (Insecta) in lotic systems from Serra da Bodoquena, Mato Grosso do Sul State, Brazil. A systematic survey was carried out in four lotic systems from Serra da Bodoquena, the largest natural forests of the State, from August 2007 to November 2008. 548 specimens belonging to 33 species, distributed in 5 families were sampled. Libellulidae was dominant, with 13 species, followed by Gomphidae, Coenagrionidae, Protoneuridae and Calopterygidae. |

| Fauna of Simuliidae (Diptera) from the state of Espírito Santo, Brazil: Distribution, new records and list of species. The fauna of Simuliidae in Brazil is composed of 87 species, 17 of which are recorded from the state of Espírito Santo. Entomological collections were carried out in 2010-2011 with the objective of increasing the knowledge of the species richness of this family in the state. Ninety three rivers and streams were sampled, each collection being carried out in a 50m transect. During the study period 30 species were collected, 13 of which represent new records for the state, 12 of the genus Simulium and one of the genus Lutzsimulium. Among these new state records one, Simulium lobatoi, also represents a new record from southeastern Brazil. The... |

| Hydrometra argentina Berg, 1879, H. caraiba Guérin-Méneville, 1857 and H. guianana Hungerford & Evans, 1934 are newly recorded in the Amazon River floodplain, Brazil. A redescription of H. argentina is also given, as the original description is incomplete. A key to the three known species occurring in this region is provided. Hydrometra argentina can be distinguished from H. caraiba and H. guianana by the body length smaller than 12.50 mm, anteoculus/postoculus ratio between 1.80 and 2.00, clypeus narrow and conical, metacetabulum with no circular pits, and projections on male abdominal sternite VI in the shape of simple spines. The other species can be distinguished mainly by the anteoculus/postoculus ratio and position of projections on male... |

| Based on material collected on streams and lakes from the Amazon River floodplain, Brazil, Microvelia urucara sp. nov. is described, illustrated and compared with similar species. The new species, like many other Neotropical Microvelia Westwood, 1834, does not present striking modifications on the body or appendages, but can be separated from its congeners by features of the male genitalia. Distributional data is presented for other veliids collected along the Amazon River, and Paravelia capixaba Moreira, Nessimian & Rúdio, 2010 and Microvelia summersi Drake & Harris, 1928 are recorded for the first time from the Brazilian Amazon. Rhagovelia jubata Bacon, 1948 is newly recorded from the state of Amazonas, and Microvelia mimula White, 1879,... |
