In Volume I, the primitive weevil families Anthribidae, Belidae, Nemonychidae, Caridae, Rhynchitidae and Attelabidae are treated. One hundred and two genera and 400 species are catalogued. The species are illustrated by about 1035 individual drawings and black and white photographs, in addition to 650 colour photographs relating to primitive weevil families in Volumes V and VI.
Volume I includes a chapter on Nemonychidae by G Kuschel and also an important Postscript detailing some crucial taxonomic changes in several weevil subfamilies that are only dealt with in detail in the later volumes.
"This work will represent the largest-ever treatise of the most diverse group of beetles, and will be the most profusely illustrated work ever published on weevils . . . a reference work for not only coleopterists but all entomological institutions and libraries." The Coleopterists Bulletin
"The appearance of these impressive volumes is one more sign of the flourishing state of entomology in the antipodes . . . Dr Zimmerman never forgets that the study of Curculionoidea is a human activity; he writes in the manner of a cultured human being . . . such qualities are too rarely seen in major works of modern scientific specialists of any variety, and makes for unusual pleasure in reading this one."
