The Psychodidae (Diptera) of Fernando de Noronha, Brazil, with a records overview of volcanic islands fauna.

The family Psychodidae (Diptera) is recorded for the oceanic archipelago of Fernando de Noronha, represented by two genera and three species: Clogmia albipunctata Williston, Psychoda buxoides Quate, P. savaiiensis Edwards, as well as an undetermined species belonging to the tribe Pericomaini. The fauna of Psychodidae in Fernando de Noronha is remarkably inferior to the Brazilian continental fauna, including species known as cosmopolitan due to the introduction into the most varied environments by human action.

, a New Genus of Empidini (Diptera: Empididae: Empidinae) of the New World, with Descriptions of Five New Species from French Guiana and the Eastern United States.

A short fragment of mitochondrial DNA for the taxonomic identification of blow flies (Diptera: Calliphoridae) in northwestern South America.

Blow flies are of medical, sanitary, veterinary, and forensic importance. Their accurate taxonomic identification is essential for their use in applied research. However, neotropical fauna has not been completely studied or described, and taxa identification without the required training is a difficult task.

Vertical stratification of insect abundance and species richness in an Amazonian tropical forest.

Tropical forests are among the most biodiverse biomes on the planet. Nevertheless, quantifying the abundance and species richness within megadiverse groups is a significant challenge. We designed a study to address this challenge by documenting the variability of the insect fauna across a vertical canopy gradient in a Central Amazonian tropical forest.

Are publications on zoological taxonomy under attack?

Taxonomy is essential to biological sciences and the priority field in face of the biodiversity crisis. The industry of scientific publications has made extensive promotion and display of bibliometric indexes, resulting in side effects such as the Journal Impact Factor™ (JIF) mania. Inadequacies of the widely used indexes to assess taxonomic publications are among the impediments for the progress of this field.
