Brakemyia, a New Neotropical Jackal Fly Genus of Milichiidae (Insecta: Diptera) Associated with Carton Ant Nest.

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.

Flesh Flies (Diptera: Sarcophagidae) From the Brazilian Amazonian Savannas, a Poorly Sampled and Threatened Environment.

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) reared from an ant nest.

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.
