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
Mythicomyia Coquillett (1893) has a disjunct distribution (presence in every biogeographical region with the exception of the Palearctic) and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. Its subgenus Heterhybos Brthes has a Nearctic and Neotropical distribution. Of the nine species in the Neotropical Region (in Argentina, Chile, and Uruguay), all occur in Chile and only one in Argentina and Uruguay. A new species of Mythicomyia (Heterhybos) is here described from Colombia: Mythicomyia (Heterhybos) bilobata sp. nov. (type-locality: Liborina, La Sucia). Illustrations of the new species, dichotomous key (males and females) and distribution map of the South American species are also presented.

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.

Glabellula Bezzi, 1902 has a cosmopolitan distribution and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. One new species of Glabellula is described from Colombia, namely Glabellula antioquensis sp. nov. (type-locality: Buriticá, La Angelina). Illustrations and a dichotomous key to the South American species are presented.

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.

Pieza Evenhuis, 2002 has a New World distribution and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. We recorded for the first time the genus Pieza in Colombia with two species, namely Pieza rafaeli Mendes et al., 2019 and we described Pieza globosa sp. nov. (type-locality: Sabanalarga, Boca de Niquia) from arid zones of a Tropical dry forest. Illustrations and a distribution map are presented.

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.

While adding taxon names to the Systema Dipterorum database (Evenhuis Pape 2021), one of us (NLE) discovered that Humboldt (1819) had spelled the proposed name of a nominal mosquito species in two ways. He described the species, which was found in swampy places along the Magdalena River near Tenerife, Colombia, as Culex cyanopennis on page 340 and afterwards referred to it as Culex cyanopterus on pages 345 and 349. Both names have the same meaning: cyano- (Gr. kyanos, dark blue), pennis (L. penna, feather, wing) and pteron (Gr. feather, wing). The species was named for the perceived color of the wings: "Alæ cæruleæ, splendore semi-metallico " (wings blue, a bright semi-metallic). On page 345, Humboldt states, translated from the French: "We have been informed in the Rio de la Magdalena that in Simitì no other Culex than the jejen [je·jén: Sp., gnat, mosquito] was known in the past. You can spend the night there quietly, because the jejen is not a nocturnal insect. Since the year 1801, the big blue-winged mosquito (Culex cyanopterus) has shown itself in such abundance that the poor inhabitants of Simitì do not know how to get a peaceful sleep." Thus, in addition to having the same meaning, the two names are associated with the same locality.

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.
