In recent decades, major advances in the systematics of Western Hemisphere genus Paracloeodes Day have been made South America. Despite taxonomic progress, uncertainties identification remain due to morphological similarities among some nymphs and general lack knowledge imago stages (only 4 20 are described from throughout range genus). This study addresses these impediments part through description male imagoes six species (P. atroari Nieto Salles, P. binodulus Lugo-Ortiz McCafferty, ibicui...
The first phylogenetic study of Callibaetis Eaton indicated an unrevealed diversity in this genus, including four new species named as sp. A, B, C and D, the undescribed nymph (Abaetetuba) fasciatus (Pictet). Given that neither C. (Ab.) nor received a proper description, objective is to describe them. differs from others subgenus by presence one row setae on basal part inner-dorsal maxilla metanotum without spines; A described cochlea nov. having trapezoid segment III labial palp nymphs; B...
Due to historical taxonomic impediments, species of Callibaetis Eaton are difficult identify. Recent studies have attempted resolve this problem, although many still lack complete descriptions; nymphs several remain undetermined; and type specimens lost or poorly known. Given these hindrances, the aim study is review some from South America. This provides a series additions corrections supported by improved morphological evaluations, illustrations photographs camposi Navás, C. (Abaetetuba)...
Paracloeodes Day is a western hemisphere genus with 20 species, but only three of these valid species are known from continental North and Central America. Based on available literature comparisons, species-level identifications can be difficult. Considering the apparent similarity between them, main objective this study was to examine type other material housed in Purdue Entomological Research Collection University Minnesota order evaluate status elucidate additional diagnostic characters....
A remarkable new predatory species of Baetidae was collected in a relict patch Amazonian savanna Brazil. The feeding habit the nymph this is very rare mayflies. composed more than 900 species, but only 12 are considered to be predators; South America, recognized as predator Harpagobaetis gulosus Mol 1986. objectives study describe brigada sp. nov., based on nymphs and amend diagnosis genus. confirmed by gut-content analysis direct observations behavior. Based similar morphological...
The taxonomic knowledge of Baetidae has been greatly improved in the last decades South America. Despite advances, there are problems that need to be addressed. One these is doubt concerning systematics species assigned genera Paracloeodes Day, Rivudiva Lugo-Ortiz & McCafferty, and Varipes evolution long setae on femora. In present paper, monophyly three tested using a cladistic approach. matrix included 53 151 morphological characters: 127 for nymphs 24 adults. dataset was analyzed...
One new taxon was brought to light during an Ephemeroptera survey in Roraima state, but it not described. This included a cladistics analysis (as Gen A) order delimitate some Baetidae genera, and recovered as genus. Taking account that the genus species status were already defined previously published paper, objective of this study describe based on imagoes nymphs, formally name Macuxi tunamore gen. nov. sp. The is sister group Rhopyscelis Cruz, Salles & Hamada + Varipes Lugo-Ortiz...
The genus Apobaetis Day is known by its small size and larval shifting-sand habitat preference (psammophilous). Three species of this are recorded in North America, from these, only lakota McCafferty needs to be redescribed because original description incomplete, turning difficult distinguish it with similar morphology. Therefore, one the objectives study redescribe A. lakota. Based on redescription, two new Brazil, morphology could identified described (Apobaetis biancae sp. nov. jacobusi...
Based on nymphs collected in Espírito Santo and Amazonas, Southeastern Northern Brazil, two new species of the genus Rivudiva Lugo-Ortiz McCafferty, 1998 (Ephemeroptera: Baetidae) are described. inma sp. nov. shares several characteristics with R. minantenna 1998, but can be distinguished by details leg setation, such as length shape robust setae presence trochanter. oonirikoperi is more similar to trichobasis separated absence scape pedicel, distal margin labrum, maxillary palp.

The genus Apobaetis Day is one of the few lineages family Baetidae distributed throughout continental Americas. Three very similar species this genus—Apobaetis etowah (Traver), signifer Lugo-Ortiz & McCaffety, and fiuzai Salles Lugo-Ortiz—have important morphological details, pertinent to identification, that remain be described. This lack detailed taxonomic information has resulted in ample misdiagnoses species, particularly regarding A. South America. In fact, almost all recently...
A new species of Bessierus Thomas & Orth, formerly a monotypic genus, is described from Amapá State, Brazil. The type the B. doloris had only its nymphs until recently, when male imago was associated to mainly based on pigmentation pattern. riobranco sp. n. here has no significant difference pattern doloris, thus could be and putative species, or even both imagoes species. Still, existence cannot neglected we opted provide properly description, diagnosis illustration, hence contributing...
This study addresses the Linnean and Wallacean deficits within Polymitarcyidae Banks, 1900 in state of Rondônia, Brazil. is significantly affected by anthropogenic activities such as agriculture highway construction. Despite extensive research on Brazil, particularly northern region, there has been a notable absence data from creating major gap our understanding its distribution. Collections conducted Rondônia 2016, 2018, 2022 10 sites have recorded 13 species discovery three new species:...
Abstract Environmental changes are increasingly frequent, resulting in adverse impacts on biodiversity. These effects more harmful when superimposed areas of high biodiversity such as the Amazon region, which gaps knowledge number existing species and how they distributed. This article reviews known geographical distributions Ephemeroptera Brazilian based current uneven sampling effort to identify hotspots poorly protected, where work is required address conservation needs this group.

Abstract Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment ecosystem health, well test ecological hypotheses. Despite their importance, a comprehensive, global database aquatic insect occurrences for mapping biodiversity in macroecological studies applied research is missing. We aim fill this gap present the Global EPTO Database , which includes worldwide geo‐referenced occurrence records four major...

SUMMARY Managed grasslands provide environmental and agronomic services that can be predicted from the botanical functional composition of vegetation. These are influenced by management, edaphic climatic factors. The present report set out to estimate analyse relative importance soil climate factors on characteristics grassland A 178 French having a large pedoclimatic management gradient was selected, information collected composition, management. Six vegetation were considered: two...
Abstract Baetidae was one of the first families established for mayflies (Ephemeroptera). After more than 200 years progressive research, is now known as most species‐rich family in order. Two competing proposals division were proposed: Cloeoninae and Baetinae, or Protopatellata Anteropatellata. Both classifications without cladistic support. The purpose this paper to investigate phylogenetic relationships using morphological evidence evaluate these classification schemes. matrix included...
Abstract Cloeon dipterum is one of the rare exotic aquatic insect species found in American continent. The was recently introduced to Argentina. Apart from a few recent records concentrated small area Argentina, there are no data available on its distribution Using modelling techniques, we predicted for first time current and future areas high invasion risk South America. We produced models (SDMs) using six algorithms based 4672 occurrences 20 environmental variables both conditions...
This study focuses on the Baetidae family of Ephemeroptera, particularly Pan-American genus Apobaetis Day, 1955, in Brazil. is second richest this order, with over 1100 species globally. Although extensively studied Brazil, there still a considerable Linnean deficit, emphasizing need for further exploration and identification. research reveals that in-depth studies specific groups often lead to discovery new corrections existing records, enhancing accuracy We conducted detailed resulting...
