The current classification of weevils has witnessed vast improvements at higher phylogenetic levels, though much remains unstable at the lower levels. In order to develop a more robust morphological character system for cladistic analysis of the higher lineages and to gain a comprehensive understanding of the structure of a hallmark feature of weevils, a comparative study was conducted of rostra throughout Curculionoidea. Semithin sections were made of the rostra of 36 exemplar genera representing all seven currently recognized weevil families, as well as 19 of 21 subfamilies within the largest family, Curculionidae, and internal structures were examined for phylogenetically informative characters. While the morphological diversity of rostral forms is impressive, general trends are apparent with respect to life-history traits and modes of feeding. Exploration of internal rostral morphology has yielded valuable but previously unexplored characters that greatly complement the external characters of this structure. Together, these features provide new insight for settling current incongruence at the higher levels of classification.

Australian Weevils: Volume IV covers the 11 smaller tribes of the weevil subfamily Entiminae (broad-nosed weevils), which comprises more than 100 genera and 700 described species in Australia. Around half of this fauna is covered in Volume IV, featuring keys to all the tribes, genera and described species as well as updated concepts and diagnoses of the tribes and summarising accounts of the taxonomy, nomenclature, distribution and known hostplants of all the genera and species. All the introduced species of Entiminae in Australia, most of which are regarded as agricultural or horticultural pests, are included, as are descriptions of 12 new genera and eight new species and identifications of about another 240 undescribed species. The book also includes an overview of the salient characters of the Entiminae, illustrated on 18 colour plates of diagnostic features needed for identifying these weevils, alongside a further 180 colour plates illustrating the habitus and genitalia of all the genera and of several other species and their diagnostic characters. The volume further includes an obituary and full publication list of the late Elwood C. Zimmerman as well as an updated list of recent literature on the Australian Entiminae and other weevils. The book is an essential reference work for researchers and students working with entimine weevils both in Australia and abroad. It is part of the Australian Weevils series.

This handbook is the third, and final, part covering the 'true weevils". Illustrated keys are provided for the identification of the genera and species of the Curculioninae (excluding Ellescini-Dorytomina, Conini, Smicronychini and Styphlini), Baridinae and Orobatidinae. Notes on the species include characters for distimguishing the sexes and information on the biology, larval foodplants, dsitribution within Great Britain and Ireland, and zoogeographical range. Those species with current 'Red Data Book' or 'Notable' status are indicated.

This volume covers the remainder of the primitive weevils (Division Orthoceri), namely the families Brentidae, Eurhynchidae and Apionidae. It catalogues 43 genera and 173 species and features almost 2000 individual drawings and black-and-white photographs. These illustrations are augmented by 270 full-colour habitus photographs in Volumes V and VI. The volume also includes an important chapter on the Immature Stages of Australian Curculionoidea by Brenda May, New Zealand, which describes the larval and pupal stages of 158 species of Australian weevils and features overviews of larval characters and their nomenclature as well as of rearing and preservation techniques applicable to weevil larvae. More than half the drawings in the volume accompany this chapter.
