(Universidade Federal do Pará, 2014-04-03) CAMARGO, Sofia Lins Leal Xavier de; CARVALHO FILHO, Fernando da Silva; http://lattes.cnpq.br/7987049452090800; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273
Description and comparative morphological notes of female terminalia of species of Peckia Robienau-Desvoidy, 1830 (Diptera, Sarcophagidae) from the Brazilian Amazon. In order to contribute and allow specific identification of female of the genus Peckia, the terminalia of 15 species that occurs in Brasilian Amazon are described, illustrated and an identification key to females is given. Besides gena color and the presence of setulae in gena and calypter, the shape of spermathecae and tergite 6 can also be used in the subgenus determination. The sternites 6, 7 and 8, the position of spiracle 6 and the microtrichosity of tergite 6 reveled important to specific identification. The tergite 8 is present only in the species Peckia (Pattonella) intermutans (Walker, 1861). The shape of vaginal plate, a structure present only in four species of subgenus Peckia, differs in shape and can be used to characterize these species. Therefore, a combined analysis of these features of female terminalia is necessary in the species determinationof the females of Peckia. Peckia (Peckia) hilifera (Aldrich, 1916) is recorded for the first time from Brazil.

A fauna de califorídeos e sarcofagídeos (Insecta, Diptera) das matas e clareiras com diferentes coberturas vegetais da base de extração petrolífera, Bacia do Rio Urucu, Coari, Amazonas
(Universidade Federal do Pará, 2008-07-21) SOUSA, José Roberto Pereira de; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273
This research was done at the oil extraction field of Urucu River in Coari, Amazonas, during the months of April, June and October of 2007, in 16 areas, 12 of them forest clearings and four forests, arranged in four environments (C1,C2,C3 and MT) according to type of forest cover. The objective was to study the composition, abundance, wealth, and diversity of Calliphoridae e Sarcophagidae (Insecta, Diptera) and also assess the possibility of these taxons to be used as parameters for evaluation of the condition of vegetal recuperation in clearing areas. The number of calliphorid collected were 7.215 (three subfamilies, eight genera and 16 species), being Chloroprocta idioidea (Robineau-Desvoidy,1830) (88,06%) and Paralucilia adespota Dear,1985 (4,35%) the most abundant species. The patterns of calliphorid abundance did not differ among the environments, however the e distinctive in relation to the estimated richness and diversity, forming two groups (C1-C2) and (C3-MT). The ordination analysis (non-metric multidimensional scaling) showed that the environment differed among themselves, as well as a greater similarity between C1-C2 and C3-MT, in relation to the structure of calliphorid communities. From the Sarcophagidae family 3.547 species were collected, distributed in 10 genera, six subgenera and 23 species , being Sarcodexia lambens (Wiedemann,1830) (47,05%) and Peckia (Peckia) chrysostoma (Wiedemann,1830) (19,11%), the most abundant species. The patterns of abundance, estimated richness and diversity for this family differed among environments and separated them into two groups, one from the clearings (C1,C2 and C3) and the other from the forest (MT). The ordination analysis (non-metric multidimensional scaling) showed a separation between sarcophagid fauna from clearings and those from the forests. The canopy cover influenced the pattern of abundance of Eumesembrinella randa Sarcophagidae family, only the abundance of Peckia (Pattonella) intermutans species (Walker,1861) was greater on environments with higher rates of forest canopy. The abundance of Oxysarcodexia amorosa (Schiner,1868), O. fringidea (Curran & Walley,1934), O. thornax (Walker,1849), P. (P.) chrysostoma and S. lambens species presented a negative linear relation with the forest canopy. These results indicate the possibility for use of these patterns as parameters to assess change in the vegetation structure.

Sarcophagidae 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.

Revisão taxonômica e análise filogenética das espécies de Retrocitomyia Lopes, 1983 (Diptera: Sarcophagidae)
(Universidade Federal do Pará, 2018-12-17) SOUZA, Caroline Costa de; PATIU, Cátia Antunes de Mello; http://lattes.cnpq.br/6111953763967066; CARVALHO FILHO, Fernando da Silva; http://lattes.cnpq.br/7987049452090800
Retrocitomyia Lopes, 1983 is a Neotropical genus of medium-sized flesh flies (5-11 mm), characterized mainly by the postgonite laterally curved and pointed apex. This genus comprises 10 valid species which biology is poorly known. The taxonomic revision of the genus resulted in 11 species, being one new species, Retrocitomyia silveirai sp. n. All species are redescribed and illustrated. Distribution maps and an update of key for male identification is provided. In addition, it is proposed a hypothesis of the phylogenetic relationship to the species of the genus, based on 19 external morphological characters of male adults, mainly from terminalia. The analysis has 14 terminal taxa, being 11 ingroup and three outgroups. The monophyly of Retrocitomyia was recovered sustain by four autapomorphies: (1) abdominal ST5 with posterior arm long, (2) abdominal ST5 with median lobe rounded, (3) median lobe of abdominal ST5 protruding, (4) cercus with a dorsal concavity. The result of phylogenetic analysis shows a basal polytomy included the type-species (R. retrocita) and R. mizuguchiana, R. silveirai sp. nov., R. adolenda, e R. fluminensis. Besides that, the analysis recovered a clade (Clade A) formed by (R. andina, (R. mexicana + R. trinitatensis), (R. sisbiota + (R. urumajoensis + R. paraguayensis)).

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/2112497575917273
Nephochaetopteryx 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.

(Universidade Federal do Pará, 2019-08) SOUZA, Matheus Tavares de; CARVALHO FILHO, Fernando da Silva; http://lattes.cnpq.br/7987049452090800; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273; https://orcid.org/0000-0001-8735-5338
The family Sarcophagidae (Diptera) has a cosmopolitan distribution, comprising 3.000 describeds species in 355 genera. Sarcophaginae is the most abundant and diverse subfamily in the new world. There are few studies about the family from Neotropical region, especially from Brazilian Amazon region, where there are few taxonomists. Therefore, this study enlarge the knowledge on the fauna of Sarcophaginae from the Brazilian Amazon, through descriptions and redescriptions of species and confection of dichotomous key to species of this region. This work was based on bibliographic survey and specimens from Brazilian Amazon housed in four entomological collections of Brazil. Morphological analysis, measurements and drawings of male species was presented. 132 species and 31 genera of Sarcophaginae from Brazilian Amazon have been found. Was made a description of a two new specie of the genus Dexosarcophaga and one Rettenmeyerina . A redescription of the monotypic genus Promayoa Dodge, 1966, was made with new illustrates. A keys to males are also provided, except for the species of the genus Lepidodexia , because the large number of undescribed Neotropical species of this genus would make any effort premature pending a complete revision of the fauna.
