Encyclopedia of South American Aquatic Insects: Ephemeroptera : Illustrated Keys to Known Families, Genera, and Species in South America

This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic revision of any group undertaken, although recommendations for such revisions are included where appropriate, and probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user ofthe key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number ofspecies. This has already been done for the order Collembola. This book is the second in a series designed to facilitate identification of South American insects likely to be encountered in, on, or near water and wetlands. After a general introduction to the study of Ephemeroptera, the mayflies, it provides illustrated keys for the identification of all species in South America that were described by the beginning of 2002. It is the only up-to-date comprehensive work of its kind encompassing the entire South American continent. The many illustrations facilitate identification of a mayfly specimen to species with reasonable certainty if the life stage has been described. If it has not been described, that is also clear from the information in the keys, letting taxonomists know where future studies would be fruitful. The book will be indispensable to all scientists and students investigating the mayflies of South America.
