Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. We are therefore proud to launch this major series. Volumes will as a minimum contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e. g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume three focuses on Dytiscidae (Coleoptera).

The beetle genus Agrilus has over 3000 species which makes it the most numerous in the Animal Kingdom. Many species are serious pests of plants with high invasive potential. Among them, the notoriously known Agrilus planipennis invaded from Asia to North America where it killed tens of millions of ash trees, caused regulatory agencies to enforce quarantines and cost municipalities, property owners, nursery operators and forest products industries tens of millions of dollars. The monograph provides coherent, comprehensive and critical review on all known host plants for more than 680 Agrilus species. All host plants have assigned the confidence index from 0-3 based on the evaluated reliability which eliminates false records. All original and subsequent references for particular plants are cited at each Agrilus species. Data are organized from both, insect and plant viewpoints. Results are analyzed and illustrated by graphs and diagrams. The main impact of the monograph is seen in entomology, phytopathology, forestry, agriculture ecology and biocontrol.

Coleoptera: Elmidae and Protelmidae contains a complete list of subfamilies, tribes, subtribes, genera, subgenera, species and subspecies, and their synonyms described before 2015. Protelmidae are here elevated from tribal rank to family rank. Other new nomenclatorial and taxonomic acts include a new substitute name, seven new generic and specific synonymies, four new combinations, two designations of type species and eight mandatory corrections of incorrect original spellings. Detailed information about the geographical distribution of each species is provided. This catalogue includes extant taxa (147 genera and 1497 species of Elmidae, four genera and six species of Protelmidae) and fossil taxa (two genera and five species of Elmidae). It is the first world catalogue of Elmidae published since 1910. Unavailable names are listed as well. Detailed explanations are provided concerning the availability and correct spelling of taxa names, correct identity and spelling of author names, correct publication dates, and correct type localities.

The present Catalogue comprises information on 48 genera and 1802 valid species of the coleopterous subfamily Scaphidiinae. Unlike previous catalogues of the group, it gives exact type localities, depositories and sexes of primary types whenever traceable. Genera are listed with their type species and grammatical gender. References are given to subsequent taxonomic and nomenclatural acts, records, and to all other relevant information. Distributional information is provided per country, for larger or insular countries per subunits. An overview of fungus and slime mould hosts is annexed. The references to all taxa have been checked by the author. Infrasubspecific entities and priorities are dealt to comply with the ICZN. Nomenclatural problems are highlighted, and several new records are given. Extinct taxa are listed separately.

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.

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.

ÿThis volume includes fourteen research articles on Canadian Coleoptera, mainly on the families Staphylinidae, Leiodidae, Histeridae, Nitidulidae, Cucujidae, Phalacridae, Silvanidae, Laemophloeidae, Tetratomidae, several aquatic groups, and others. An introductory editorial traces the history of scientific research and indicates areas of future inquiry. The papers address various questions with respect to the distribution, dispersal, zoogeographical status, phenology, and bionomics of Canadian Coleoptera, the role of saproxylic beetles in forest ecosystems, and invasive species in native habitats. The answers to these questions have important economic and environmental consequences. The book is addressed to coleopterists, ecologists, biogeographers, and conservationists.
