Now Available from CABI Illustrated keys are provided for the families, genera, species and other taxa of British and Irish Hydradephaga. The Hydradephaga comprise the Gyrinidae, Haliplidae, Noteridae, Paelobiidae (also known as Hygrobiidae) and the Dytiscidae. Colour plates are provided of all the species. Notes include characters for distinguishing the sexes, some basic information on biology and collecting methods, and reviews of distributions in Ireland and Britain, including the Channel Isles.

Now Available from CABI Illustrated keys are provided for the families, genera, species and other taxa of British and Irish members of the superfamily Hydrophiloidea (Coleoptera suborder Polyphaga). The Hydrophiloidea comprise the families Helophoridae, Georissidae, Hydrochidae, Spercheidae, and the Hydrophilidae. Most of these beetles are aquatic and this book is the second part of the Handbook series concerning water beetles. However, this work includes terrestrial Helophorus and many species in the subfamily Sphaeridiinae of the Hydrophilidae. Notes include characters for distinguishing the sexes, basic information on biology and collecting methods, and reviews of distributions in Ireland and in Britain, including the Channel Isles. A key to all families of aquatic beetles is appended.

The first comprehensive book in more than a century to reveal the diversity and natural history of diving beetles. Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred. In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188 Dytiscid genera ever assembled. Entomologists, systematists, limnologists, ecologists, and others with an interest in aquatic systems or insect diversity will find these extensively illustrated keys and taxon accounts immensely helpful. The keys make it possible to identify all taxa from subfamily to genera, and each key and taxon treatment is accompanied by both photographs and detailed pen-and-ink drawings of diagnostic features. Every genus account covers body length, diagnostic characters, classification, species diversity, a review of known natural history, and world distribution. Each account is also accompanied by a range map and at least one high-resolution habitus image of a specimen. Diving beetles are fast becoming important models for aquatic ecology, world biogeography, population ecology, and animal sexual evolution and, with this book, the diversity of the group is finally accessible.

A chapter on Staphylinidae in a 1976 book on marine insects was the last general work on coastal rove beetles worldwide. Since then, phylogenetic studies on rove beetles have yielded a different perspective on that family, now with well over 50,000 species. Almost 400 species of them are now believed to be restricted to sea coasts. The detailed distribution and current classification of the coastal species are here documented in a review of the world literature accompanied by discussion and numerous color photographs of habitus and habitat.
