ABSTRACT
Brakemyia metallica gen. et sp. nov. (Diptera, Milichiidae) is described and illustrated based on male and female specimens reared from carton nests of the ant Azteca aff. chartifex Forel (Formicidae: Dolichoderinae). The new genus is widely distributed in the Brazilian Amazon, and it can be readily distinguished from the other Neotropical genera by the broadened lunule, which extends well posterior of the antennae, and the hypandrial complex parallel to epandrium.
ABSTRACT
The Amazonian region is composed by many kinds of environments, including the Amazonian savannas, which comprise about 5% of the Amazon biome in Brazil. The biota of Amazonian savannas is poorly known, especially for insects. In this study, we performed a faunistic inventory of flesh flies (Diptera: Sarcophagidae) of four Brazilian Amazon savannas, where we recorded two subfamilies, 16 genera, and 40 species, two of which are described as new to science: Lepidodexia (Notochaeta) helenae sp. nov. and Lipoptilocnema augustoi sp. nov. Oxysarcodexia graminifoliaSouza, Pape & Thyssen, 2020 is recorded for the first time for Brazil. Dexosarcophaga paulistanaLopes (1982), Helicobia biplagiataDodge, 1966, Helicobia cearensisTibana, 1976, Oxysarcodexia simplicoides (Lopes, 1933), and Oxyvinia excisa (Lopes, 1950) are newly recorded for the Brazilian Amazon. Oxysarcodexia nitidaSoares & Mello-Patiu, 2010 is a new record for the state of Pará. The species D. paulistana is redescribed, and photographs and detailed illustrations of male terminalia are provided.

A new species of Neoscutops Malloch (Diptera: Periscelididae), Neosctups rungae sp. nov., is described from the Brazilian Amazon based on three specimens (2 males and 1 female) reared from carton nests of the ant Azteca aff. chartifex Forel (Formicidae: Dolichoderinae). The new species belongs to the rotundipennis species-group, which is now composed of five valid species. The new species can be readily diagnosed by the following combination of characters: face fully dark brown and surstylus with a basal rounded projection on inner margin.

The dipteran fauna from the Brazilian Amazon remains poorly known, including that of forensic interest, such as the Sepsidae. The sepsid fauna of two secondary forests in the eastern Amazon was surveyed utilizing rotting bovine lung and feces (humans, bovines, and monkeys). We obtained 17 sespid species in six genera, most of them on bovine dung and rotting bovine lung. Two new species are described herein: Archisepsis bosque sp. nov. and Archisepsis verae sp. nov. The genus Palaeosepsis Duda, 1926 and the species Archisepsis polychaeta (Ozerov, 1993), Archisepsis diversiformis (Ozerov, 1993), Microsepsis mitis (Curran, 1927), Meropliosepsis sexsetosa Duda, 1926, and Palaeosepsis cf. golovastikOzerov, 2004 are newly recorded from the Brazilian Amazon.

A new species of Sarcophagidae (Diptera) in the genus Helicobia Coquillett, Helicobia neuzalmeidae sp. nov., is described based on two male specimens obtained from pig carcasses in savanna-like vegetation in northeastern Brazil (state of Maranhão) during a forensic study. The holotype was obtained from a larva that abandoned the pig carcass to pupate, whereas the paratype was collected with a trap placed above the cage containing the carcass. This is the first record of a Helicobia species reared from a vertebrate carcass.

Two new species of Dexosarcophaga Townsend (Diptera: Sarcophagidae) are described, both from the coastal zone of the Brazilian Amazon: Dexosarcophaga salgada sp. nov. and Dexosarcophaga klycyae sp. nov.

The subfamily Chloropinae comprises about 442 described species, with only one species recorded from the Brazilian Amazon. The genus Bricelochlorops Paganelli was represented by a unique species from Rio de Janeiro, Brazil. The species Urubambina rufa (Duda) is the only species of the genus Urubambina Paganelli and has been recorded only from Peru. A new species of Bricelochlorops, B. celutae sp. nov., is described here and Urubambina rufa is recorded for the first time in Brazil. Both species were collected in the state of Acre. A key to species of Bricelochlorops is provided.

The present study brings together survey data from collection in several localities in the Brazilian Amazon and specimens from the Entomological Collection of Museu Paraense Emílio Goeldi (MPEG-Belém). The flies were collected over organic decomposing matter (bananas and bovine meat) baits. The genus Odontoloxozus Enderlein, with the species Odontoloxozus peruanus Hennig, is recorded from Brazil for the first time. The species Glyphidops (Glyphidops) flavipes (Widemann), G. (Oncopsia) flavifrons (Bigot), G.(O.) durus (Cresson) and G. (O.) dipsar (Hennig) are new occurrences for Brazil. The species G. (O.)carrerai Aczél and N. plurivittatus Bigot are new occurrences from Brazilian Amazon. A key to Brazilian Amazon species is provided.
