Gagne's introductory chapters include biographical sketches of those individuals who have contributed most to our knowledge of Neotropical gall midges. He also discusses classification and distribution, external anatomy and biology, and techniques for collecting, rearing, and preparing specimens for study. The heart of the book comprises two chapters. The first presents the midges themselves: identification keys to the genera, a synopsis of each genus and higher taxon, and a list of all known species from South America. The second includes keys and descriptions of galls and other damage caused by the midges, with known hosts.
Having received such lavish praise for the first volume of his definitive taxonomic handbook, Daniel Otte now turns his attention to the bandwing grasshoppers. As before, the book includes: - Highly detailed, full-color drawings of all species, including more than one color phase when appropriate; - Illustrated keys and lists of principal recognition features; - Information on distributional limits, habitat preferences, ecology, behavior, and life cycle; - Excellent point-distribution maps; - Pertinent references, taxonomic index, history of name changes, and an explanation of the characters used to derive phylogenies. Like its predecessor, this volume will be useful to scientists in agriculture, environmental assessment, biogeography, grassland ecology, and insect taxonomy. It will also appeal to amateur naturalists.
Members of the large grasshopper genus Orthochtha are widely distributed throughout the Afrotropics with some representatives in India and the Far East. The taxonomy of the genus has, however, long been recognized by acridologists to be unsatisfactory. This publication provides a thorough revision of Orthochtha together with seven allied genera, of which three are erected here. In all, 36 species and 11 subspecies are treated, of which 16 species and 5 subspecies are described here as new. All taxa are diagnosed, illustrated, keyed, mapped and their affinities discussed. The biogeography of the group is considered and a synopsis of the available information of the biology, ecology and economic importance given for each species. This book will be of use both to taxonomists and to agricultural field workers, particularly in Africa.
