The result of more than 20 years of research and collaboration by international butterfly experts, this book is the first comprehensive catalogue to the butterfly fauna of any major tropical region and, as such, provides a basic research tool for any worker with an interest in African butterflies. Covering 3593 recognised species in 300 genera, it deals with about 20% of the world butterfly fauna. Included are entries for all genus-group, species-group and infra-subspecific names applicable to the Afrotropical butterflies, a total of about 14 000 names. This work has a more wide-ranging appeal than a narrow taxonomic list, a volume that will be of value not only to taxonomists but to all biologists with an interest in Africa and its butterfly fauna.
