	abstract = {The west-Palaearctic species of Cephalops and Beckerias are revised. Sixteen species are recognized including one new to science. Among the taxonomic changes proposed: C. curtifrons is considered a junior synonym of Beckerias pannonicus. The results of a phenetic and cladistic analysis are given. Berkerias is considered to be closely related to Cephalops but is still treated as a separate genus until the phylogeny of the pipunculid genera is better understood. A key and diagnostic descriptions are given for all species. The male and female terminalia and other taxonomically significant structures are illustrated. The geographical distribution is given as far as known.},

	abstract = {This book is volume 8 in a multi-volume work which catalogues the main taxonomic, nomenclatorial and distribution data of 25 000 fly species described from the Palaearctic Region. In this volume the families Syrphidae, Pipunculidae and Conopidae are catalogued. For each family, a brief introduction is provided which gives information on the life cycle, distribution and number of species in the family, and describes the adult and (if known) the larva. Extensive references to the literature are given.},
