RESUMO
A new cave-dwelling species of Ptiloneuropsis from southeastern Brazil, is here described based on both sexes, illustrated and named as: Ptiloneuropsis krenaki sp. nov. This new species differs from Ptiloneuropsis immaculata Roesler, 1940 and Ptiloneuropsis diamantina Silva-Neto, Garca Aldrete & Rafael, 2018 in details of the hypandrium and phallosome. In addition to the third new species of the Ptiloneuropsis, descriptions of variation in the fore and hindwings veins are also given. The diagnosis of Ptiloneuropsis is updated, and P. immaculata is redescribed. Furthermore, the first identification key for Ptiloneuropsis species, based on males, is presented.

A new species of Triplocania Roesler included in the magnifica species-group is here described, illustrated and named as: Triplocania oiapoque n. sp. based on male and female specimens. In addition to the fourth new species of the magnifica species-group, descriptions of variations in forewing venation were also made for it, as well as an additional description of the ejaculatory duct, accessory glands, and spermatic sacs, recorded for the first time in Triplocania species. A new geographic record for Triplocania magnifica Roesler and an updated species key for the magnifica species-group are also presented.

Two new species of Brasineura are described from Brazil based on male specimens: Brasineura calori sp. n. (Bahia: Brazil) and Brasineura morrense sp. n. (Bahia: Brazil). They differ from the other species in the genus, in which the males are known, by hypandrium and phallosome structures. New records and comments on variation in the fore- and hind- wing venation of B. troglophilica Silva-Neto García Aldrete and B. diamantina Silva-Neto García Aldrete are presented. The identification key to male Brasineura species is updated.

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.
RESUMO
The three new species of Brazilian Euplocania are described and illustrated, two species belong in the amabilis species group (Euplocania maraca sp. nov. and Euplocania ufrr sp. nov.) and one species belong in the marginata species group (Euplocania macuxi sp. nov.). Information on species groups, species subgroups and distribution by Brazilian states is included for known species of Euplocania.(AU)

The holotype of the Neurostigma xanthopterum New, 1980 is here illustrated based on photographs. We also describe and illustrate a previously unknown female individual that is assigned to this species. New records for five localities in the Brazilian state of Amazonas, one in the Brazilian state of Acre and another in the Brazilian state of Amapá, are presented. The mouthparts of both sexes are here describe and illustrate. Thirteen types of variation and anomalies in the fore-hindwing veins were found. We found unique patterns in the number and shape of transverse veins in the pterostigma between individuals. We also identified a large variation in the denticles present in the lacinia. Therefore, we suggest these variable characteristics (fore-hindwing veins and lacinia denticles) are not to be used for the diagnosis of species of this genus. A revised diagnosis of N. Xanthopterum is also presented.(AU)

There is much information regarding the association of Psocoptera and coffee as stored grain pests and little is known about their presence in coffee plants. We conducted a survey in a coffee plantation of Coffea canephora in the municipality of Candeias do Jamari, Rondônia state, Brazil, where we obtained the first record of a coffee plant as a host of Psocoptera in the Brazilian Amazon region, and the first record of a representative of the family Archipsocidae (Archipsocus lenkoi) for the state of Rondônia. The psocid population was concentrated and not evenly distributed over the survey area, which indicates an irregular distribution pattern. We have not detected damage or injury to the coffee plants and therefore we cannot consider these psocids as a pest in the coffee plantation.(AU)
Há muita informação sobre a associação de Psocoptera e café como peste em grãos armazenados, mas pouco se sabe sobre sua presença nas plantas do café. Nós realizamos uma amostragem em uma plantação de café de Coffea canephora no município de Candeias do Jamari, Rondônia, onde obtivemos o primeiro registro de uma planta de café como hospedeira de Psocoptera na Amazônia brasileira e o primeiro registro de um representante da família Archipsocidae (Archipsocus lenkoi) para o estado de Rondônia. A população de psocídeos estava concentrada e não distribuída uniformemente na área de amostragem, o que indica um padrão de distribuição irregular. Não detectamos danos ou injúrias nas plantas de café e, portanto, não podemos considerar esses psocídeos como uma praga na plantação de café.(AU)

The phylogenetic relationships of the genera of Ptiloneuridae were inferred on the basis of morphological characters of adult specimens. Two distinct clades are recognized: one, including Belicania, Euplocania, Omilneura, Perucania, Timnewia and Triplocania, and the other, including Brasineura, Loneura, Loneuroides, Ptiloneura, Ptiloneuropsis and Willreevesia. Brasineura and Loneuroides are recognized as monophyletic. A correction of nomenclature for the parts of the phallosome in Brasineura was made; we also modified the identification key to the genera of Ptiloneuridae, in the couplets that separate Loneura from Brasineura.

Abstract Four species of Triplocania collected in the Brazilian state of Bahia, are described and illustrated, based on male specimens, namely: T. annyae sp. nov., T. diamantina sp. nov., T. lauzie sp. nov. and T. miltoni sp. nov. They differ from the other species in the genus, in which the males are known by hypandrium and phallosome structures. New records of T. capixabaSilva-Neto, García Aldrete & Rafael, 2016 and T. manueliSilva-Neto, García Aldrete & Rafael, 2016 for the state of Bahia are presented. In addition, an update on the Triplocania internal classification is proposed.
RESUMO
Here it is shown that Loneura crenata Navás, 1927 and Loneura ocotensis García Aldrete are distinct species, so the previously proposed synonymy of the latter with the first is not valid. Illustrations of the L. crenata holotype, deposited in the Hamburg University Zoological Museum, are here presented for the first time.(AU)
