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.

This revision comprehensively documents species of the shore-fly genus Hydrochasma Hendel, which is one of three genera of the shore-fly tribe Discocerinini (subfamily Gymnomyzinae) that occurs exclusively in the New World. The other two genera are Pectinifer Cresson and Facitrichophora Mathis & Zatwarnicki. All known species of Hydrochasma are described with an em-phasis on structures of the male terminalia, which are fully de-scribed and illustrated. In addition, detailed locality data and dis-tribution maps for all species are provided. Among New World genera of Discocerinini, Hydrochasma is perhaps the least well known, as indicated by the dramatic increase in recognized species reported in this revision. Before this revision, Hydrochasma included just seven species, and herein we more than quadruple that number by adding 27 previously undescribed species. These additions bring the total number of congeners to 34. 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. With clarification of species ? how they can be recognized and where they occur ? we hope that additional research on immature stages and other aspects of their natural history and ecol-ogy will be fostered and facilitated.

This revision significantly documents a continuing trend in the discovery and documentation of New World shore flies (Diptera: Ephydridae). Two genera of the tribe Discocerinini are treated: Facitrichophora, new genus, with all four included species being newly described, and Polytrichophora Cresson with 19 species, including 11 that are newly described. Previously, eight species were known from the New World. The authors emphasize structures of the male terminalia, which are fully described and illustrated, in the recognition of species and species groups. 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, which documents an ongoing need for field work and better taxon sampling of earth?s shore-fly fauna.

In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

Birding and butterfly watching have been popular outdoor activities for decades. Now, dragonfly watching is catching on as a fascinating and enjoyable pursuit. Dragonflies are large, colorful insects with amazing and easily observed behavior. Noted entomologist Dr Robert Cannings introduces students, naturalists and outdoor enthusiasts to the world of dragonflies. In this compact book, he shows readers where to find dragonflies and how to watch and study them in the field. In the introduction, Dr Cannings outlines the natural history of these insects - their structure, life cycles, habitats and behavior. Then he describes the 88 species known in British Columbia and the Yukon, noting habitat preferences and distribution. To make identification easy, each description has one or more color photographs and comparisons with similar species.
