Efferia okanagana, a New Species of Robber Fly (Diptera: Asilidae) from the Grasslands of Southern British Columbia, Canada, with Notes on Taxonomy, Biology, Distribution, and Conservation Status

Abstract Efferia okanagana sp. nov. is described from specimens collected in the grasslands of the southern Interior of British Columbia, Canada, mainly the Okanagan Valley. The male and female genitalia are described and illustrated. The existing key to species of Efferia Coquillett is modified to enable identification of male and female E. okanagana. The species belongs to the E. arida species group and perhaps is most closely related to E. arida (Williston) and E. pinali Wilcox. Efferia coulei Wilcox is the closest sympatric relative. Sequences of the cytochrome oxidase I gene (DNA barcode) for E. okanagana and E. coulei show distinct clusters for each species that are approximately 7.0% divergent (uncorrected p distance). Efferia okanagana has an early flight period (May and June) and lives in low-elevation grasslands dominated by bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) Á. Löve) (Poaceae), especially where the soil is gravelly. It is considered a potential species at risk by the Committee on the Status of Endangered Wildlife in Canada.

期刊介绍： French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
