RESUMO
This research aims to describe the process of ecological succession by associating the decomposition stages of pig carcasses with flies from the Calliphoridae family (Diptera). For this, 6 pig carcasses were exposed in Maranhão's Cerrado, utilizing metal cages with sawdust trays to catch immature specimens and "suspended traps" to capture adults. Adults of the Hemilucilia benoisti Séguy, and Hemilucilia townsendi Shannon species were only associated with the swelling stage. Chrysomya megacephala (Fabricius) was associated with 2 stages (black putrefaction and fermentation). The species Chloroprocta idioidea (Robineau-Desvoidy), Chrysomya albiceps (Wiedemann), Cochliomyia macellaria (Fabricius), and Lucilia eximia (Wiedemann) were associated with 4 of the 5 stages of decomposition, the latter being the only 1 associated with the initial stage. The larvae abandoned the carcasses to pupate from the second stage of decomposition, with L. eximia being the only 1 leaving the carcasses in the swelling stage, and C. albiceps the only 1 associated with both the fermentation and dry stages. Our findings indicate that calliphorid species can help forensic investigators estimine the post-mortem interval of cadavers in situations similar to those detailed in this study. Since there was a link between adult and immature species and certain stages, they can be used as indicators in future forensic investigations.

The genus Termitozophilus Silvestri (Coleoptera: Staphylinidae: Aleocharinae: Corotocini) is composed of three species that are associated with termite nests of the genus Cornitermes Wasmann in South America. Although this termite genus is widespread in the Amazon region, the species of the rove beetle genus Termitozophilus associated with it are less known. In this paper, we describe four new species of Termitozophilus species from the Brazilian Oriental Amazon. Furthermore, we provide information on natural history, post-imaginal growth, behavior, and a taxonomic key to all valid species.

The minute litter bugs (Heteroptera: Schizopteridae) fauna from the Brazilian Amazon comprises only nine species described during the past four years. In this paper, the Schizopteridae fauna of an Amazonian savanna was surveyed, resulting in the discovery of two new species of Corixidea Reuter and a new species of Schizoptera (Cantharocoris) McAtee Malloch: Corixidea graziae sp. nov., Corixidea quilombola sp. nov., and Schizoptera (Cantharocoris) savannensis sp. nov. The species C. graziae sp. nov. and C. quilombola sp. nov. can be distinguished from other Corixidea species by the shape of the process of mediotergite 8 while S. (Cantharocoris) savannensis sp. nov. can be recognized among species of its subgenus by a combination of the shape of the subgenital plate and right conjunctival appendage. The species herein described represent the first records of these genera for the Brazilian Amazon. We provide diagnoses, photographs of habitus, and illustrations of male genitalia.

Nephochaetopteryx Townsend, 1934 is a genus of flesh flies predominantly Neotropical in distribution, which comprises small species (4.0-7.3 mm) characterized mainly by vein R1 fully setulose dorsally and wing usually fumose between apical part of vein R2+3 and vein C. The taxonomic revision of the genus resulted in 39 valid species, of which 12 are new to science: N. boruca sp. nov., N. canga sp. nov., N. coendu sp. nov., N. cuzco sp. nov., N. equatoriana sp. nov., N. inca sp. nov., N. lamasi sp. nov., N. matinta sp. nov., N. psittacocercus sp. nov., N. sofiae sp. nov., N. similis sp. nov. and N. tembe sp. nov. Nephochaetopteryx shannoni Dodge, 1968 is a junior synonym of N. flavipalpis Lopes, 1936, syn. nov. and N. linharensis Tibana Santos 1997 is a junior synonym of N. pallidifacies Lopes 1975, syn. nov. A key to the males of all valid species is given, as well as detailed illustrations of the male terminalia.

The present study aims to document the community composition, abundance, and species richness of saprophytic fly species (Mesembrinellidae, Neriidae, Ropalomeridae, and Sarcophagidae) of the Volta Grande region of the Xingu River, a poorly sampled area impacted by the Belo Monte hydroelectric dam. Five collecting trips were carried out between 2014 and 2016, when traps baited with fermenting bananas were used. A total of 154 specimens, three genera, and six species were collected of Mesembrinellidae; 196 specimens, three genera, and seven species of Neriidae; 272 specimens, three genera, and six species of Ropalomeridae; and 624 specimens, 22 species and 10 genera of Sarcophagidae. Species accumulation curves for all families except Sarcophagidae demonstrated a strong tendency towards stabilization, showing that sampling efforts were sufficient to record most of the targeted species. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) is a new record for the state of Pará. Among Ropalomeridae, Apophorhynchus amazonensis Prado, 1966, is a new record for Pará. Among Sarcophagidae, Helicobia aurescens (Townsend, 1927) is newly recorded from the Brazilian Amazon, and Ravinia effrenata (Walker, 1861) and Titanogrypa larvicida (Lopes, 1935) are new records for Pará.
O presente estudo teve como objetivo documentar a composição, abundância e riqueza das espécies de moscas saprófitas (Mesembrinellidae, Neriidae, Ropalomeridae e Sarcophagidae) da Volta Grande do rio Xingu, uma área pouco amostrada e impactada pela Hidrelétrica Belo Monte. Foram realizadas cinco expedições de coleta entre 2014 a 2016, quando foram utilizadas armadilhas contendo banana em fermentação como isca. Foram coletados 154 espécimes, três gêneros e seis espécies de Mesembrinellidae; 196 espécimes, três gêneros e sete espécies de Neriidae; 272 espécimes, três gêneros e seis espécies de Ropalomeridae; e 624 espécimes, 22 espécies e 10 gêneros de Sarcophagidae. As curvas de acumulo de espécies para todas as famílias, exceto Sarcophagidae, demonstraram uma forte tendência à estabilização, mostrando que o esforço amostral foi suficiente para registrar a maioria das espécies-alvo. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) é um novo registro para o estado do Pará. Entre os Ropalomeridae, Apophorhynchus amazonensis Prado, 1966, é um novo registro para o Pará. Em relação aos Sarcophagidae, Helicobia aurescens (Townsend, 1927) é um novo registro para a Amazônia Brasileira e Ravinia effrenata (Walker, 1861) e Titanogrypa larvicida (Lopes, 1935) são novos registros para o Pará.
RESUMO
The minute litter bug genus Corixidea Reuter, 1891 currently comprises nine valid American species. Herein, we describe Corixidea quaresmai sp. nov. from one of the last remaining remnants of Atlantic Forest in northeast Brazil. The new species is characterized by the distal extension of the anophoric process parallel and close to the left lateral margin of the tergites, and the elongated process of tergum 8, with a pectinate distal half and a filiform tip. We provide diagnosis, images of habitus and male genitalia.(AU)

RESUMO
The family Termitaphididae and the species Termitaradus trinidadensis (Morrison) are recorded for the first time from Brazil. This species had been found only in Trinidad and Tobago and is redescribed based on specimens collected in Heterotermes tenuis (Hagen) termite nests from forested and open areas in the Brazilian Amazon. Scanning electron micrographs of integumental ornamentation, illustrations of male and female terminalia, and pictures of live specimens are provided for the first time.
