New record of Pterotaenia fasciata (Wiedemann) (Diptera, Ulidiidae) in Brazil, a probably mechanical vector of enteric bacteria

Pterotaenia fasciata is commonly recorded in rural areas in Argentina, but during a Diptera survey study developed in a reservoir which retains storm water from polluted canals in an urban area of Taboão da Serra municipality, SP, Brazil, we could capture P. fasciata adults. Enteric bacteria Escherichia coli T. Escherich, 1885 and Proteus sp. were isolated from P. fasciata collected in traps inside the reservoir and around it. Fecal coliforms and E. coli were found in the water of the reservoir. These records suggest that a high abundance of this species at urban areas with inadequate sewage canals should reveal these muscoid dipterans as mechanical vectors of enteric bacteria.

Biogeographic analysis of Crocidiinae (Diptera, Bombyliidae): finding congruence among morphological, molecular, fossil and paleogeographical data

Biogeographic studies dealing with Bombyliidae are rare in the literature and no information is available on its origin and early diversification. In this study, we found evidence from molecular phylogeny and from fossil record supporting a Middle Jurassic origin of the Bombylioidea, taken as a starting point to discuss the biogeography and diversification of Crocidiinae. Based on a previously published phylogenetic hypothesis, we performed a Brooks Parsimony Analysis (BPA) to discuss the biogeographical history of Crocidiinae lineages. This subfamily is mostly distributed over arid areas of the early components of the Gondwanaland: Chile and southern Africa, but also in southwestern Palaearctic and southwestern Nearctic. The vicariant events affecting the Crocidiinae biogeography at the generic level seems to be related to the sequential separation of a Laurasian clade from a Gondwanan clade followed by the splitting of the latter into smaller components. This also leads to a hypothesis of origin of the Crocidiinae in the Middle Jurassic, the same period in which other bombyliid lineages are supposed to have arisen and irradiated.

The last instar larva and the pupal case of Ommatius orenoquensis Bigot, 1896 from a Cerrado (Brazilian Savanna) area in São Paulo, southeastern Brazil, are for the first time described and illustrated.

Navicordulia aemulatrix sp. nov. (Odonata, Corduliidae) from northeastern Santa Catarina State, Brazil

Navicordulia aemulatrix sp. nov. (holotype male deposited in MZSP: Brazil, Santa Catarina State, [São Bento do Sul municipality, 26°14'58"S, 49°22'59"W], [railroad station] Rio Vermelho, II.1952) is described and illustrated based on three males. The long cercus (2.9-3.2 mm) places this species in the longistyla-group together with N. kiautai, N. longistyla and N. nitens but it differs from them mainly by the shape of cercus, with carinated part occupying 0.33 of cercus total length, and also by dorsal, ventro-medial and ventro-lateral tubercles developed. An unusual process on tergal portion of prothorax is reported for the first time in Navicordulia. The rate of description of new species of South American 'Corduliidae' is discussed. A map with records of Atlantic Forest Navicordulia species and a list of Brazilian corduliids by state are also presented.

O artigo aborda os resultados de um estágio desenvolvido, no Laboratório de Educação Digital da Universidade Jean Piaget de Cabo Verde no âmbito do projecto de desenvolvimento do Sistema de Informação Académico onde nos foi proposto projectar, desenvolver e testar um modelo de representação de eventos e sumários, bem como desenvolver uma rotina que permita converter os dados no formato de dados utilizado pela aplicação iCal. Para se atingir os objectivos acima propostos foi desenvolvido um modelo de representação de eventos e actas recorrendo a ferramentas UML. Posteriormente o modelo foi implementado e testado recorrendo a um SGBD orientado a objectos (ORACLE 10g). Por fim foi desenvolvida uma rotina que permite efectuar a migração e conversão dos dados extraídos da base de dados num ficheiro utilizado pela aplicação iCal.

Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay

Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay. This paper provides comments on the subspecific taxonomy and geographic distribution of Sais rosalia (Cramer, 1779) (Lepidoptera, Nymphalidae, Ithomiini), as well as an up-to-date distributional map, complemented with unpublished distributional data based on specimens deposited in the Coleção Entomológica Pe. Jesus S. Moure, Curitiba, Brazil and the Museo de Historia Natural, Lima, Peru. The following synonyms are proposed: Sais rosalia camariensis Haensch, 1905 syn. rev. as junior subjective synonym of Papilio rosalia Cramer, 1779 and Sais rosalia brasiliensis Talbot, 1928 syn. rev. as junior subjective synonym of Sais rosalia rosalinde Weymer, 1890. Additionally, the first country records of Sais rosalia in Paraguay, including the southernmost record of the species, are documented.

A new species of Stempellina Thienemann & Bause from Mato Grosso do Sul, Brazil (Diptera, Chironomidae)

A new species of Stempellina Thienemann & Bause from Mato Grosso do Sul, Brazil (Diptera, Chironomidae). The male imago of Stempellina sofiae sp. nov. is described and illustrated based on material collected in Mato Grosso do Sul, Brazil, during the expeditions of the project SISBIOTA Brazil. One of the core focuses of this project is identifying and describing new species of Diptera from central Brazil. The new species herein presented can be easily segregated by their congeneric by the rounded shape of the superior volsella.

Un conjunt faunístic de finals de l'Antiguitat Tardana al jaciment de Santa Margarida (Martorell, Baix Llobregat)

El present treball analitza les restes de fauna procedents de la UE 3006 de l'església de Santa Margarida (s. VIII d.C.). El conjunt és compost majoritàriament per deixalles alimentàries de macromamífers, aus i mol·luscs. La ponderació del nombre de restes, l'anàlisi de la representació anatòmica i l'estudi de les traces d'origen antròpic han permés establir la composició de la cabana ramadera al jaciment i els patrons de gestió dels animals amb fins alimentaris (corba de mortalitat i patró d'especejament dels animals). El conjunt dóna testimoni de l'alimentació d'origen càrnic del baix clergat a finals de l'Antiguitat tardana.

Aplicação seqüencial de cloreto de mepiquat em algodoeiro

Com o objetivo de avaliar o efeito de doses de cloreto de mepiquat aplicadas de forma parcelada, foi conduzido, em Jaboticabal, SP, um experimento com a cultivar de algodoeiro IAC 22. O delineamento experimental foi o de blocos casualizados, com 13 tratamentos e 4 repetições. O efeito do cloreto de mepiquat sobre a redução da altura das plantas foi mais evidenciado pela dose total aplicada do que pelo uso do esquema de parcelamento. A menor dose estudada (55 g/ha) foi suficiente para que as plantas, por ocasião da colheita, estivessem com altura inferior a 1,30 m. O cloreto de mepiquat proporcionou redução no comprimento dos ramos e um melhor equilíbrio entre as partes reprodutiva e vegetativa. As características peso de capulho, peso de 100 sementes, porcentagem de fibra e produção de algodão em caroço, não foram significativamente afetadas pelos tratamentos.
