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
The studying material were recently collected with Malaise traps in Northeastern Brazil, and the authors found a new species of Amydrostylus, which represents the second known species of this endemic genus from the open/dry biomes of Brazil. The discovery results will provide more new diagnosis for the genus and allow a better knowledge of the male terminalia morphology, leading to a new interpretation of some of its structures. Male and female specimens are described and illustrated here.

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.

Studying material recently collected in Brazil, the authors found three new species of Glabellula (G. catiapatiuae sp. nov., G. rafaelae sp. nov., G. sarahae sp. nov.) that are described and illustrated herein. An identification key to the Brazilian species is also presented. This paper presents the first records of Glabellula in South America and the presence, for the first time, of the subfamily Glabellulinae in Brazil.

The genus Pieza Evenhuis, 2002 has 11 known species but only one recorded from Brazil. In this paper, eight new species, P. ankh sp. nov., P. aurislepus sp. nov., P. bittencourti sp. nov., P. parakake sp. nov., P. parnasecon sp. nov., P. rafaeli sp. nov., P. silvanae sp. nov. and P. yeatesi sp. nov., are described from Maranhão and Piauí in the Northeast of Brazil. A key to genera of Mythicomyiinae of the world (modified from Rafael and Limeira-de-Oliveira 2014) and the Brazilian species of Pieza is provided. In addition, a distribution map for the Brazilian species of Pieza is presented.
