  journal={Studies on Neotropical Fauna and Environment},
Three new genera and three new species of Baetidae (Insecta: Ephemeroptera) are described from the Andes and Patagonia. Larvae of Andesiops, new genus, are distinguished by the apically bifid right prostheca and two rows of denticles on the tarsal claws. Larvae of Deceptiviosa, new genus, are distinguished by the apically bifid right prostheca and small subapical denticle on the tarsal claws. Larvae of Nanomis, new genus, are distinguished by the apically acute maxillary palp segment 2, smooth…

The senior genus-group name for the holophylum including the muticus-group is Takobia/g1; in rank-based nomenclature the names Alainites Waltz & McCafferty and Acerbaetis Kang & Yang should be junior synonyms of Takobia Novikova & Kluge 1987 (new synonymy).

Ephemeroptera and Plecoptera biodiversity in central Patagonia, Chubut province, Argentina

The first preliminary inventory of Plecoptera and Ephemeroptera taxa for the area is presented and include seasonal records of adult stages and reinforces the idea that patagonian aquatic environments have a highly specialized and complex insect fauna which can be correlated with biogeographical aspects but also with a great environmental heterogeneity.

Andesiops peruvianus (Ephemeroptera: Baetidae): a species complex based on molecular markers and morphology

The results of this study show that A. peruvianus represents a species complex, with four putative species inferred, contributing to the growing knowledge of the existence of pseudocryptic species.

Revision of South American species of Baetidae (Ephemeroptera) previously placed in Baetis Leach and Pseudocloeon Klapálek

South American species of small minnow mayflies that have been previously placed in Baetis Leach or Pseudocloeon Klapalek are revised and the presence of Fallceon and Moribaetis in South America is confirmed for the first time.

New species of Nanomis Lugo-Ortiz and McCafferty, 1999 (Ephemeroptera: Baetidae) from Venezuela

As the first taxonomic and faunistic report of Nanomis Lugo-Ortiz and McCafferty, 1999 for Venezuela, we describe a new species, N. rasmusseni sp. n., based on material from Andean streams.

Composition and structure of the Baetidae family (Insecta: Ephemeroptera) in a Colombian Andean basin

The family Baetidae was related with type of substrate, as well as variables such as; pH, alkalinity, hardness, total solids, electrical conductivity, BOD5, dissolved oxygen, water flow and nitrates, which suggest a potential influence of anthropogenic effects on species establishment.

A non-paraphyletic classification of the afrotropical genus Acanthiops Waltz & McCafferty (Ephemeroptera: Baetidae)

Acanthiops Waltz & McCafferty (Ephemeroptera: Baetidae) is shown to be a monophyletic grouping defined by an anteromedially emarginate and laterally expanded and flattened pronotum in the larva.

The family Baetidae (Insecta: Ephemeroptera): synthesis and future challenges

The systematics of the Baetidae has been the subject of much attention during the last three decades, with descriptions of new species and genera as well as several generic revisions, so an opportune time to evaluate the pertinence of these works.


The objective of this work was to perform a preliminary study of the Ephemeroptera fauna in the department of Putumayo, which to date is unknown.

Estado de conocimiento del orden Ephemeroptera en la Patagonia

From the field work carried in 80 collecting sites during the development of the Nahuel Huapi Nacional Park, some species are recorded for the first time in Argentina, out of which 33 species belonging to 20 genera are known to occur in Argentina.



First report and new species of the genus Apobaetis (Ephemeroptera: Baetidae) from South America

The South American species is apparently plesiotypic relative to known Nearctic congeners, suggesting a Neotropical center of origin for Apobaetis.
