RESUMO
A new monotypic genus is described and illustrated based on the species Pugliesemyia titiznana gen. nov. et sp. nov. from the Caatinga domains of the state of Pernambuco, Brazil. It belongs to the small group of genera in the Neotropical region (Stonyx Osten Sacken, Lepidanthrax Osten Sacken, Rhynchanthrax Painter) among the tribe Villini, with a projecting proboscis. In addition, we also provide an updated identification key to the known Brazilian genera of Villini, description and illustrations of the pupal case, bionomic remarks on the feeding habits and the host record of the species and a brief discussion on Villini systematics and boundaries of their genera.
RESUMO
A new species of Tamanduamyia (Diptera, Mythicomyiidae, Mythicomyiinae) is described from Serra do Ramalho, Carinhanha, Bahia, Brazil, Tamanduamyia bichuettae sp. nov. The type series was actively collected with falcon tubes when resting at the entrance of a limestone cave in the rock exudations. The species is described and illustrated in detail, including the male terminalia and female spermathecae. This is the first record of a micro-bee fly species in the state of Bahia (Brazil) and may also represent the first recorded association of a Mythicomyiidae species with cave environments.

A new genus of Phthiriinae, Hirsutophallus gen. nov. is described, based on the examination of male and female specimens from the Andean region of Bolivia and Argentina. Hirsutophallus gen. nov. contains several characters that distinguish it from other Phthiriinae genera, such as: prominent tip on the lateral margin of the scape; lower lobes on epiphallus; prominent lateral lobes on epiphallus, with dorsal macrosetae; penial guide of distiphallus with long and dense macrosetae on dorsal surface; gonocoxite with medial process large basally and acute apex in lateral view, with short apical and ventral spines and posterior process with ventral spines; gonostylus with row of spines on apical third of dorsal and ventral surface and furca with V-shaped sclerites, with very long and curved parallel arms. The new genus, endemic to the Neotropical Region, is described to accommodate Hirsutophallus andinus gen. nov. et sp. nov. An identification key to the genera of Phthiriinae is also provided. The species is described and illustrated in detail, including the male and female terminalia.
