With more than 500 clearly drawn illustrations, Chen (entomology, National Museum of Natural History, The Netherlands), Nieser, and Zettel (Natural History Museum, Vienna) provide an introduction to the genera of adult Gerromorpha (semi-aquatic bugs) and Nepomorpha (true aquatic bugs) of Malesia and adjacent areas. The book, the first of its kind for the region, addresses the classification, nomenclature, distribution, morphology, and adaptations of these genera. It also presents identification keys for families, subfamilies and genera of both Gerromorpha and Nepomorpha for the entire Indo-Australian region. The book includes species checklists, distribution maps, a glossary and an extensive references listing. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)
