Abstract
The nearly cosmopolitan genus Nomada Scopoli is examined on a worldwide basis. A monophyletic Nomada that corresponds closely to the genus as it has been understood by most authors can be defined on the basis of apomorphic characters of the terminal metasomal segments of females and certain aspects of the male genitalia and associated sterna. Clear and unequivocal monophyletic groupings within Nomada are difficult to identify, and cladistic analyses do not discover a single most parsimonious cladogram for the groupings that are identified. A formal cladistic classification recognizing subgenera is considered premature, in view of the difficulty of defining monophyletic groups and resolving phylogenetic relationships among them. Nevertheless, an informal classification into species groups is proposed. Descriptions and diagnoses of the groups are presented, and information on geographic distribution and host relationships is briefly summarized in the species group descriptions.
