argentea Wheeler. Shenandoah (MMPC). Literature records: “ Virginia ” (Francoeur 1973, 1974, Peck et al. 1998, Guenard et al. 2012).
The only reliable Virginia record of F. argentea is that of Francoeur (1974; p. 261) which is based on examination of materials in Forel’s collection (1 worker and 1 male, “ 4-VII-1880, T. Pergande”). Records in Peck et al. (1998) and MMPC are likely based on misidentifications of the locally common Formica subsericea. More interesting is the record in Francoeur (1973; p. 150) which is based on examination of specimens (no county and locality data) at the Department of Entomology, University of Minnesota, Saint Paul. It is possible that the specimen label “ Virginia ” refers to the town of Virginia in northern Minnesota where argentea is not uncommon. Virginia records reported in Guenard et al. (2012) are based on Francoeur (1974) and Peck et al. (1998).

Literature records: Augusta, Giles, Montgomery (Cole 1949, Wang et al. 2000, Trager et al. 2007), “ Virginia ” (Mayr 1886, Emery 1893, Wheeler 1913, Gregg 1963, Young & Howell 1964, Peck et al. 1998, Guenard et al. 2012).

rubicunda Emery. Augusta, Giles, Page (FMNH, MCZ). Literature records: Augusta (Wang et al. 2000), “ Virginia ” (Buren 1968, Guenard et al. 2012).
subaenescens Emery. James City (FMNH). Literature records: “ Whitetop Mtn.” (Van Pelt 1963), “ Virginia ” (Francoeur 1974, Guenard et al. 2012).
All Virginia records of this species appear under the name Formica fusca Linnaeus. As currently understood true fusca is restricted to the Palearctic region and does not occur in North America. The Virginia record of F. subaenescens in Francoeur (1974; p. 262) is based on examination of materials in Forel’s collection (2 workers, “T. Pergande”). Van Pelt’s record from Whitetop Mtn. may also refer to F. subaenescens but we have not had a chance to examine his specimens. The record reported in Guenard et al. (2012) is based on Francoeur (1974). James City Co. is located in Virginia’s Coastal Plain and as such, the FMNH record from this locality is most likely a misidentification of F. subsericea. Formica subaenescens is a northern species, which should occur in high altitude sites in the western part of the state.
