This volume deals with the European species of the family Sepsidae, a small family of acalyptrate flies. The taxonomy, biology and faunistics of all the European species are revised with emphasis on the Fennoscandian species. Nine genera and 44 species are dealt with, along with one new species.
This beautiful volume, with hundreds of fascinating hand-drawn illustrations, completes the two-volume work on the order Odonata in the Encyclopedia of South American Aquatic Insects. The Zygoptera volume encompasses the small dragonflies often called damselflies. The sections on the morphology of the adults and larvae are followed by discussions of factors influencing their distribution and instructions on the methods used to observe, collect, preserve, and examine specimens.
Anisoptera, the first of two volumes on the Odonata, encompasses the large dragonfly species. To help readers understand naming conventions, a brief introductory biological review of the group includes illustrations of the main morphological features as well as explanations of alternative systems for naming the wing veins and other structures. The text introduces keys to facilitate identification of adult dragonflies and the known larvae. Beyond anatomical features, the keys include the known ranges of the species, synonyms, and citations of literature. The book is richly illustrated with pen and ink drawings of thousands of individual morphological structures.
This order once encompassed all insects with a complex network of wing veins, regardless of whether their metamorphosis was incomplete or complete. By the early 20th century, most of the species had been transferred to new orders, leaving only a small percentage of the insects once assigned to the Neuroptera remaining in that order. By the second half of the 20th century, some of the taxonomists began to believe that the fragmentation of this order had gone too far, and that the order Megaloptera needed to be grouped in some way with Neuroptera, either by making them suborders of the same order or by creating a superorder to accommodate both. This volume provides a discussion of both taxa, tentatively regrouping both in the order Neuroptera. While all known species of Megaloptera in South America have completely aquatic larval stages, few species in the suborder Planipennia, formerly called Neuroptera sensu stricto, are aquatic during any of their life stages. The most interesting of the exceptions are species in the family Sisyridae, some of which develop as larvae inside freshwater sponges. Because only a relatively small number of species are still included in Neuroptera sensu lato, this book provides keys to all known South American species that have been described well enough to be identified with any degree of certainty. Many species in the family Chloropidae, the neuropteran family with the greatest number of recognized species in South America, have proven to be valuable as biological controls for insect pests in agriculture. Their importance for tropical agriculture is another reason for including terrestrial species in this book. The series will continue with volumes providing keys to identify species of other South American orders, but in most cases, only aquatic insects can be included in the keys to the species.
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.
