Book Description
For the first time in limnofaunistic bibliography, the present taxonomic knowledge about the different clades of chelicerata having adapted to an aquatic or amphibious lifestyle along various evolutionary pathways is brought together in an overview for the Central-European fauna. A total number of 746 taxa is covered, over 99 % of these at species level. In Volume 7/2-1 altogether 211 species are treated - 70 species of spiders, 7 species of Astigmata (3 of which to be identified only at family, genus, resp. species group level), 17 species of Oribatida, 27 species and one subspecies of Halacaridae, 45 species of terrestrial Parasitengona (4 of which to be identified only at genus level) and 45 species of Hydrachnidia (4 Stygothrombioidea, 3 Hydrovolzioidea, 16 Hydrachnoidea and 22 Eylaoidea). Volume 7/2-2 deals with 179 species of Hydrachnidia (58 Hydryphantoidea and 121 Lebertioidea). This third volume (Volume 7/2-3) includes taxonomic keys and ecological information for 355 species of the two highly diverse Hydrachnidia superfamilies Hygrobatoidea (241 species and one subspecies) and Arrenuroidea (113 species). The chelicerata volumes of this series are a basic tool for all limnologists interested in diversity and ecology – in particular for biologists investigating the ecotones between ground and surface water, between bottom substrata and open water, and between water and land.

Book Description
The subphylum Clitellata of the phylum Annelida contains several classes of organisms dwelling in freshwater systems. The systematic concepts of these groups are still a matter of discussion at all taxonomic levels involved. It is hoped that the interrelationships of systematic entities within and above the species level will be better understood as additional and more precise data on morphology, anatomy, and genetics become available. The aim of this volume is to present a compilation of valid tax described from the western Palaearctic area, including the fauna of the Egyptian Nile, in order to serve as a fundament for future work. This contribution covers three classes of leeches: the Branchiobdellida, which live as epizoons on freshwater decapods, the small class Acanthobdellea, comprising highly specialised parasites living on freshwater fishes, and finally the class Hirudinea, which contains species commonly known as the "classical" leeches. Standardised descriptions of the morphology of all species are given. Whenever possible, these are amended by data on anatomical details to allow correct identifications. Most of the species are illustrated, many of them for the first time. The keys cover all taxa known from the geographical range under consideration. They are especially constructed to be used by biologists in the field, thus enabling fast access to an unknown species without dissection. Whenever possible, information on biology, ecology and distribution is supplied, although many of these data have to be used very carefully to avoid the hitherto known frequent misinterpretations.

Book Description
The Helophorinae are among the most distinctive of all the aquatic Coleoptera. This book gives an account of the Helophorus fauna of all Europe, Asia Minor, the Russian Transcaucasus, Israel and the Arab Middle East. Keys to the 96 known Helophorus species are provided induding details of their distribution, ecology and life history. Larvae of 45 species can be identified by a separate key and there is an illustrated account of the egg cocoons of 46 species. The general sections describe the morphology of adults and larvae and the techniques for studying Helophorus such as chromosome studies. The book is comprehensively illustrated with line drawings and stereoscan photographs.
