The first comprehensive systematic account since Robert Mertens' works of 1955 and 1971. The main text comprises species accounts for the 239 species currently known to occur in Namibia. These accounts give the specific name (including relevant subspecies) and original citation details, the locally preferred colloquial name, Namibian distribution in broad terms, Namibian conservation and legal status, international conservation and legal status, and a list of parks in which the species occurs or is expected to occur. The book also discusses taxonomic, phylogenetic and previous literature issues.
