Item Acesso aberto (Open Access) Diversidade de Calliphoridae (Insecta: Diptera) na base de extração petrolífera da Bacia do Rio Urucu, na Amazônia brasileira(Instituto Nacional de Pesquisas da Amazônia, 2010-09) ESPOSITO, Maria Cristina; SOUSA, José Roberto Pereira de; CARVALHO FILHO, Fernando da SilvaThe diversity and abundance of blow flies in three environments (anthropic gaps, tree-fall gaps, and primary "terra firme" forest) of Porto Urucu/AM were evaluated in annual collects realized in 2004, 2005, and 2006. During these three years were collected 2,121 specimens belonging to 14 species. The most abundant species were Chloroprocta idioidea (Robineau- Desvoidy), Eumesembrinella randa (Walker), and Hemilucilia semidiaphana (Rondani). Primary forests and tree-fall gaps enviroments, showed higher blow flies abundance than anthropic gaps, with diversity and equitability index higher than anthropic gaps, when the dominance value was high.Item Acesso aberto (Open Access) Feeding ecology of Dash-dot Tetra Hemigrammus belottii (Steindachner 1882) (Characiformes: Characidae) in the streams of the Urucu River basin, central Amazonia, Brazil(2013-09) GONÇALVES, Andrey Felipe Gomes; PRUDENTE, Bruno da Silveira; CARVALHO FILHO, Fernando da Silva; MONTAG, Luciano Fogaça de AssisThe present study describes aspects of feeding ecology of Dash-dot Tetra Hemigrammus belottii (Characiformes: Characidae) collected in the Urucu River basin in Coari, Amazonas (Brazil), aims to respond the following question: What is the influence of hydrological periods (dry and wet) and spatial distribution in the diet of H. belottii? The specimens were collected between 2006 and 2009 in seven streams in the Urucu basin using standard capture methods. Their stomachs were removed for diet composition analyses. The alimentary items were weighed and identified for subsequent analyzes related to feeding intensity by repletion index (RI%) and importance by alimentary index (AIi%). A total of 227 specimens were analyzed, with a mean standard length of 16.5±5.6 mm. The RI% values indicated that H. belottii fed more intensively during the dry season. The principal items in the diet were Formicidae (IAi% = 69.6), fragments of allochthonous exoskeleton (IAi% = 17.7), and Coleoptera (IAi% = 6.0). The composition of the diet did not vary significantly between seasons or among habitats, which may be related to the abundance of the items exploited by the species throughout the year. Hemigrammus belottii showed a generalist insectivore feeding habits which was mainly composed by allochthonous item.Item Acesso aberto (Open Access) On the taxonomic status of Nephochaetopteryx calida (Wiedemann) (Diptera, Sarcophagidae)(Universidade Federal do Pará, 2013-06) CARVALHO FILHO, Fernando da Silva; ESPOSITO, Maria Cristina; MELLO-PATIU, Cátia Antunes deOn the taxonomic status of Nephochaetopteryx calida (Wiedemann) (Diptera, Sarcophagidae). Based on analysis of the holotype of Nephochaetopteryx calida (Wiedemann) it was concluded that this species does not belong to Nephochaetopteryx. The holotype is a female partly damaged and it was not possible to place it in one of Sarcophaginae genera, remaining as Sarcophaga calida Wiedemann, 1830, incertae sedis.Item Acesso aberto (Open Access) Redescription of Pseudopomyzella flava Hennig (Diptera: Cypselosomatidae) and the first record from Brazil(2011) CARVALHO FILHO, Fernando da Silva; ESPOSITO, Maria CristinaCypselosomatidae is composed of Cypselosomatinae and Pseudopomyzinae, including 11 extant genera. Only the genus Rhinopomyzella Hennig (Pseudopomyzinae) has been previously recorded from Brazil, represented by two species from Santa Catarina. The genus Pseudopomyzella Hennig is comprised of a single species, Pseudopomyzella flava Hennig, previously found only in Peru and Ecuador. Here, we report P. flava for the first time from Brazil (Pará) and redescribe the species based on the specimens collected.Item Acesso aberto (Open Access) Revisão taxonômica das espécies brasileiras do gênero Argoravinia (Diptera : Sarcophagidae)(Universidade Federal do Pará, 2009-06-25) CARVALHO FILHO, Fernando da Silva; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273Sarcophagidae is a family with about 2,600 described species worldwide, with about 800 species in Neotropical region. Argoravinia Townsend, 1917 is a genus of Sarcophagidae (Diptera, Oestroidea) belonging to Sarcophaginae subfamily with Neotropical and Nearctic species, with exception of two species that were introduced in Marshal Island (Australasian/Oceanic region). The genus comprises small to large flies (4 - 9,5 mm), with R1 setulose in basal half and, one or more setae on underside of stem of vein R2+3, ejaculatory apodema large, phallus with very long median stylus, lateral stylus base free. The genus Argoravinia comprised two species until that the genus Raviniopsis Townsend, 1918, with four species, was considered synonym of Argoravinia in the Sarcophagidae catalogue, thus the genus comprises nowadays six species currently described: A. alvarengai Lopes, 1976; A. aurea (Townsend, 1918); A. brasiliana Lopes, 1976; A. candida (Curran, 1928); A. rufiventris (Wiedemann, 1830) and A. timbarensis (Lopes, 1988); however, only fours species were recorded from Brazil. In the present study, the Brazilian Argoravinia species are revised and redescribed: A. alvarengai, A. aurea, A. brasiliana e A. rufiventris. Two new are described from state of Pará: A. catiae sp. nov. and A. paraensis sp. nov. A. alvarengai is recorded for the first time from state of Pará and A. rufiventris is a new record from states of Bahia e Maranhão. An identification key for males and females specimens, illustrations of male and female terminalia, Scanning electron microscopy images, as well as distributional maps are provided.Item Acesso aberto (Open Access) Revisão taxonômica e filogenia das espécies do gênero Nephochaetopteryx Townsend, 1934 (Diptera: Sarcophagidae)(Universidade Federal do Pará, 2012-08-20) CARVALHO FILHO, Fernando da Silva; MELLO-PATIU, Cátia Antunes de; http://lattes.cnpq.br/6111953763967066; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273Nephochaetopteryx Townsend, 1934 is a genus of flies of the family Sarcophagidae, tribe Sarothromyiini, predominately Neotropical, with only one Nearctic species. This genus comprises small species (4–7.3 mm), mainly characterized by vein R1 fully setose dorsally, males with proclinate orbital bristles, and male mid femur with ctenidium. In addition, some species has wing fumose between apical part of vein R2+3 and C. The taxonomic review of the genus resulted in 34 valid species, being seven new species to science. Nephochaetopteryx calida does not belong to the genus, N. shannoni is junior synonymy of N. flavipalpis, and N. linharensis a junior synonymy of N. pallidifacies. A key to males of all described species (except for N. juquiana) is showed, as well as detailed illustrations of terminalia and sternite 5 of males. In addition, it is proposed a hypothesis of the phylogenetic relationships to the genus, based on 24 external morphological characters of adult males, mainly from terminalia. Were utilized 32 terminal taxa, being 29 of Nephochaetopteryx. The monophyly of genus is corroborated, and a new synapomorphy is proposed within the Sarothromyiini context: sternite 5 of male with median lobule. Based on the phylogenetic analyses, the genus is divided in four species group: angustifrons, biculcita, cyaneiventris and pallidiventris. The angustifrons group is the sister group of the clade that comprises the remaining species.
