This paper provided a list of all new Brazilian Hexapoda species described in 2020. Furthermore, based on the information extracted by this list, we tackled additional questions regarding the taxa, the specialists involved in the species descriptions as well as the journals in which those papers have been published. We recorded a total of 680 new Brazilian species of Hexapoda described in 2020, classified in 24...
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodivers...
The composition and potential hosts of mycophagous Drosophilidae from a section of the Brazilian Amazon forest in the Caxiuanã National forest were investigated. Sampling was performed in three different periods at long the wet season (January (beginning) and July (end) 2013 and May (middle) 2014). The samples were collected from existing trails by actively searching for fungal fruiting bodies where Drosophilid...

Description focused metanotal gland features, phallic sclerites, and calling song. A large sampling of individuals was distributed into four groups according to body and appendages color and dotted. We also rank all kind of marks...
O estudo da interação entre os indivíduos de uma mesma espécie ou de espécies diferentes é essencial para o entendimento das dinâmicas envolvidas na manutenção das comunidades ou assembléias na natureza. Assim, o estudo das preferências alimentares das larvas dos drosofilídeos, refletidas no padrão de emergência das mesmas dos sítios de oviposição, é de suma importância, uma vez que este grupo de organismos tor...
Os objetivos do trabalho foram caracterizar e comparar as assembléias de drosofilídeos em um gradiente que vai de um ambiente florestal ao urbano, e verificar se há uma variação sazonal na abundância destes indivíduos. Para isso foram realizadas dez coletas entre os anos de 2000 e 2003 em quatro pontos com diferentes níveis de urbanização na cidade de Florianópolis, SC, Brasil. Um número bastante alto de espéci...
