Genus Proceratium Roger

A single, rare species of Proceratium has been recorded from California. Endemic to the state, P. californicum Cook is known from valley oak woodland in the Central Valley and from woodland, chaparral and grassland sites in adjacent foothill localities. It is presumed to be a specialist, subterranean predator; some other members of the genus have been shown to prey on spider eggs.
