The Rove Beetles (Coleoptera: Staphylinidae) of the George Washington Memorial Parkway, with a Checklist of Regional Species
Brittain RM. 2019. The Rove Beetles (Coleoptera: Staphylinidae) of the George Washington Memorial Parkway, with a Checklist of Regional Species. Banisteria. 53:27-71
Two-hundred and nine taxa (171 identified to species level), in 111 genera, of staphylinid beetles were documented during a 21-year field survey of a national park site (George Washington Memorial Parkway) that spans parts of Fairfax and Arlington counties in Virginia. Fifty-two species, plus five additional genera, documented from the Parkway are first records for Virginia. An additional 62 species new to Virginia are listed in the appendix from broader research documenting 792 species of Staphylinidae from Virginia, Maryland, and the District of Columbia. The study also increases the number of staphylinid species known from the Potomac River Gorge to 167. Of the seven capture methods used in the survey, Malaise traps were the most successful. Periods of adult activity, based on dates of capture, are given for each species. Relative abundance is noted for each species based on the number of captures. Notes on morphological characteristics and habitats are given for some species. Thirteen species adventive to North America are documented from the Parkway and 60 adventive species are recorded from Virginia, Maryland, and the District of Columbia in the Appendix. Range extensions are documented for 16 species. Images of 11species new to Virginia are provided.
