The moth genus Lasionycta (Lepidoptera: Noctuidae), like several other genera that occur mainly in arctic and alpine areas, are highly sought but rarely encountered by noctuid enthusiasts. The diurnal species are occasionally seen by butterfl y collectors, who manage to get into these areas, but light trapping in these remote habitats is very difficult. The group has eluded a long-needed revision because many species are similar, exhibit a large amount of local and geographical variation, and insufficient material has been available for revisionary work. A large amount of material collected in the past 10 years has finally made a comprehensive revision of Lasionycta possible. Also, most of the species were evaluated using mitochondrial cytochrome c-oxidase (COI) DNA sequences, commonly called barcodes, a relatively new taxonomic tool that has only recently come into common usage. This revision treats the 43 species known to occur in North America, 17 of which are described as new. Three quarters of the North American species are involved in taxonomic changes and five species associated with Pacific Coast beaches are removed from Lasionycta and placed in Psammophila, a new genus. The revision includes 246 color images of adults and genitalia, as well as distribution maps for all species. The results will also be interesting for Palearctic researchers because four species are Holarctic and some of the other approximately 12 Old World species of Lasionycta are mentioned as occurring in Holarctic species complexes. Several Palearctic species are discussed in reference to excluding them from Lasionycta and returning them to the genera Lasionhada, Eriopygodes, and Clemathada.

This annotated list arranges the 3693 species of Noctuoidea known from North America into six families (Doidae, Notodontidae, Erebidae, Euteliidae, Nolidae, Noctuidae) and further arranges these into subfamilies, tribes, and subtribes, based on the most recent phylogenetic information. All changes from the previous list in 1983 are documented in 716 taxonomic notes and 331 literature references. These changes include documentation for 367 new species that have been described since the 1983 list, 230 species added through new records or taxonomic changes, and 259 species that are removed or synonymized. A total of 166 taxonomic changes are proposed in the list.

"Moths and butterflies (Lepidoptera) are one of the most diverse and economically important groups of insects, with approximately 157,000 species worldwide. This book establishes a definitive list of the species that occur in BC, and clarifies erroneous records in past works. It provides a knowledge baseline that will be useful to resource and conservation managers, biodiversity researchers, taxonomists, amateur collectors, and naturalists."--Back cover.

This checklist of the Lepidoptera (butterflies and moths) of Alberta lists 2367 species reported to occur in the province, as well as 138 species whose occurrence in Alberta is probable. Each species entry includes adult flight time and distribution status in the Cordilleran, Boreal, and Grasslands ecozones, as well as references to taxonomic works and to the literature and public collection sources of the records. Detailed notes on taxonomy, nomenclature, distribution, habitat, and biology are given for 1524 of the listed species. An additional section provides details on 171 species erroneously reported from Alberta in previous works. The authors hope it will be a useful resource for anyone carrying out species-level work on Lepidoptera in western Canada, or taxonomic work on Lepidoptera in general. An introductory section provides a general overview of the order Lepidoptera and the natural regions of Alberta, and the history and current state of knowledge of Alberta Lepidoptera. Each of the 63 families (and selected subfamilies) occurring in Alberta is briefly reviewed, with information on distinguishing features, general appearance, and general biology. The list is accompanied by an appendix of proposed nomenclature changes, consisting of revised status for 25 taxa raised from synonymy to species level, and new synonymy for 20 species-level and one genus-level taxa here considered to be subjective synonyms, with resultant revised synonymy for one taxon and formalization of seven new combinations.
