This volume contains richly illustrated keys and descriptions of the 157 species of predaceous diving beetles (Dytiscidae) found in Fennoscandia, Denmark and the Baltic States. Information about biology and distribution is included, as is a catalogue of provincial records.

This volume treats the 157 species of predaceaous diving beetles (Dytiscidae) found in Finland, East Fennoscandia, Sweden, Norway, Denmark and the Baltic States. Introducing chapters provide general information about the state of knowledge and distribution, morphology of adults and larvae, bionomics, collecting and rearing. The main part comprises keys and descriptions for identification of adult beetles, including information on distribution and biology of all species. A catalogue shows provincial records in Fennoscandia and Denmark. The book contains 608 figures and 3 plates. An up-to-date, well illustrated identification manual for the Fennoscandian and Danish Dytiscidae has been wanting for decades. This work is based on the latest advances in synonymy and taxonomy of the family, and on the study of thousands of specimens in collections and field.

The book provides richly illustrated identification keys and descriptions of the ca. 240 Nordic springtail species of Entomobryomorpha and Symphypleona, thus completing the survey which was introduced with the first volume on Poduromorpha in 1998.

This volume completes the survey of the ca. 400 species of springtails, which can be found in Finland, Sweden, Norway, Denmark, Iceland, the Faroes and the Arctic Islands and includes the sections Entomobryomorpha and Symphypleona. The first volume, published in 1998, covered Poduromorpha. Identification keys and full descriptions of the species are richly illustrated by line drawings. Photos are provided for some species displaying characteristic patterns of pigmentation. New diagnostic characters, including sensillary chaetotaxy and details of the mouth apparatus, are introduced. With the appearence of this book soil scientists and the interested amateur have now a modern tool to identify all species of Nordic springtails. In addition the habitat preferences and geographical distribuition are summarised. The book will be of general interest to everyone working on springtail identification.

This three-volume series represents a comprehensive treatment of the beetles of Australia, a relatively under-studied fauna that includes many unusual and unique lineages found nowhere else on Earth. Volume 2 contains 36 chapters, providing critical information and identification keys to the genera of the Australian beetle families included in suborders Archostemata, Myxophaga, Adephaga and several groups of Polyphaga (Scirtoidea, Hydrophiloidea, Scarabaeoidea, Buprestoidea and Tenebrionidae). Each chapter is richly illustrated in black and white drawings and photographs. The book also includes colour habitus figures for about 1000 Australian beetle genera and subgenera belonging to the families treated in this volume. This volume is a truly international collaborative effort, as the chapters have been written by 23 contributors from Australia, China, Czech Republic, Germany, Italy, Poland and USA.

This book is a revised edition of the first of three volumes in the Handbook of Zoology series which treats the systematics and biology of Coleoptera. With over 380,000 described species, Coleoptera are by far the most species-rich order of insects and the largest group of animals of comparable geological age. Moreover, numerous species are tremendously important economically. The beetle volumes meet the demand of modern biologists seeking to answer questions about Coleoptera phylogeny, evolution, and ecology. This first Coleoptera volume covers the suborders Archostemata, Myxophaga and Adephaga, and the basal series of Polyphaga, with information on world distribution, biology, morphology of all life stages, phylogeny and comments on taxonomy.

The 2nd edition of this comprehensive book provides one of the most complete overviews of the aquatic beetles in the family Dytiscidae, also known as predaceous diving beetles. Dytiscids constitute one of the largest families of freshwater insects with approximately 4,650 named species that come in a variety of sizes, colors, and habitat affinities. Although dytiscid adults and larvae are ubiquitous throughout a variety of aquatic habitats, and are important predators on other aquatic invertebrates and vertebrates, there are no compilations that have focused on summarizing the knowledge on aspects of their ecology, systematics, and biology. Chapters in this book summarize hitherto scattered topics, including their anatomy and habitats, chemical and community ecology, phylogenies and larval morphology including chaetotaxy, sexual systems, predation, dispersal, conservation, and cultural and historical aspects. The 2nd edition offers updates on the newest scientific findings on dytiscids and also includes a new chapter on the subterranean fauna from Australia. The information in this new edition is potentially beneficial to anyone working in aquatic systems where dytiscids are an important part of the food web. Moreover, readers will gain a greater appreciation of dytiscids as model organisms for investigations of fundamental principles derived from ecological and evolutionary theory. Contributed chapters are by authors who are actively engaged in studying dytiscids, and each chapter provides color photos and future directions for research.

This book is the first comprehensive account on the flea fauna of Fennoscandia and Denmark. Totally 89 species/subspecies are treated of which 69 have been found in the region. The remainder are known from neighboring areas and may turn up. The introductory part gives a brief historical overview of the earliest literature on fleas and a more detailed account of the Scandinavian literature up to the present. This is followed by a discussion of flea-host associations in relation to distribution in a general and Scandinavian perspective. Other chapters deal with life history, medical importance, morphology and collecting/preservation of fleas, and are followed by a flea–host index. The systematic part, amply illustrated with Frans Smit’s outstanding line drawings, provides identification keys to adult fleas from family to subspecies. For each species/subspecies relevant available information on synonymy, identification, distribution, host relations and biology is given. The book concludes with a summary of the provincial distribution of fleas in Fennoscandia and Denmark, a bibliography and a taxonomic name index.
