Based on material from Brazil, Colombia, and French Guiana, two new species of Paramaka are described. The male imago of Paramaka lucimarae sp. nov. can be distinguished based on the following characteristics: abdominal color pattern uniformly tinged with orangish-brown; posteromedial projection of styliger plate short and not curved; telopenis bas...

This study addresses the Linnean and Wallacean deficits within the Polymitarcyidae Banks, 1900 in the state of Rondônia, Brazil. This state is significantly affected by anthropogenic activities such as agriculture and highway construction. Despite extensive research on the Polymitarcyidae in Brazil, particularly in the northern region, there has be...

Polymitarcyidae has a worldwide geographic distribution. Their nymphs are adapted to the fossorial habit, while the adults (imagos) have atrophied legs, except for the anterior legs of the males. This study represents the first survey of this family in the western region of Pará. For this purpose, we collected nymphs and adults. Nymphs were capture...

In Colombia have been recorded eight species of the family Caenidae distributed in three states, at the moment do not exist species reported in the Meta state. In this paper, Caenis cuniana Froehlich, 1969 (Caenidae: Ephemeroptera) is registered for the first time from Colombia, in the same way, Brasilocaenis irmleri Puthz, 1975 and Caenis chamie A...

Abstract Aquatic insects of the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT) have a wide distribution and play an important ecological role in aquatic ecosystems, primarily in nutrient cycling in lotic systems. They also exhibit high morphological and functional diversity. Although there are numerous studies evaluating the morphological...

Despite the growing number of studies on mayflies (Ephemeroptera), especially in terms of description of new species and distributional records, the knowledge generated remains scattered across specialized literature. This dispersion poses a challenge for non-specialists, such as ecologists, hindering their ability to promote studies and conservati...

The Leptophlebiidae family of mayflies is diverse, with over 640 species and 140 genera worldwide. One of its subfamilies, Terpidinae, is restricted to the Neotropical region and consists of three genera, including Fittkaulus, which have four South American species. This paper redescribes the male imago and proposes a new synonym based on the reari...

Caenidae is a globally widespread family, inhabiting a variety of aquatic habitats. In South America, only 35 species are recognized, maybe as a consequence of the few studies until the first decade of the 21st century. Despite recent advances, large portions of Brazil, such as Rondônia State, are still characterized by Linnean and Wallacean shortf...

A new genus and two new species of the family Platyarthridae are described from the Brazilian state of Piauí, Paratrichorhina piauiensis n. gen. et n. sp. and P. taitii n. gen. et n. sp. Similarities and differences with the other genera of the family are discussed, and a key to the family is provided.

In-stream conditions can affect the distribution of the Ephemeroptera, Plecoptera, and Trichoptera orders (EPT) because they require specific food resources and good quality water. Therefore, we evaluated the association between the different facets of the EPT diversity (genera richness, beta diversity, and abundance of individuals) and an environm...

Hagenulopsis diptera Ulmer, type species of the genus Hagenulopsis, was originally described based on imagos from Santa Catarina State, Southern Brazil. Misconceptions of H. diptera circumscription led to erroneous attribution of material from Minas Gerais and Espírito Santo, Southeastern Brazil, to H. diptera. Despite the increase in the number of...
