Book excerpt: This revision comprehensively documents the New World species of the shore-fly genus Gymnoclasiopa, which primarily has a Holarctic distribution, including some species that are found in both the Nearctic and Palearctic Regions. Discovering additional species common to both biogeographic regions was an objective of this study, as was unraveling any nomenclatural issues that resulted when the same species was described separately in both biogeographic regions. Ten species are treated, including two that are newly described. The authors also document the obvious sexual dimorphism that is evident in some species but which was not previously appreciated, resulting in confused concepts of some species. The authors emphasize structures of the male terminalia, which are fully described and illustrated, in the recognition of species. In addition, detailed locality data and distribution maps for all species are provided. Much of this increase has resulted from a greatly improved sampling of the New World fauna, documenting the ongoing need for field work and better taxon sampling of the earth?s shore-fly fauna.
