San Mateo Co., California
This rarely collected ant is known from valley oak (Quercus lobata) riparian woodland in the Central Valley and from adjacent foothill localities (oak woodland; chaparral; grassland). It is presumed to be a specialist, subterranean predator on spider eggs. Alates have been collected in April and May.
