The Palearctic rhyparochromid Rhyparochromus saturnius (Rossi) [Lygaeoidea] is reported for the first time in North America based on collections from 17 counties in California. Literature pertaining to this adventive species is reviewed, notes on its habits are given, and descriptions and photographs of the adult and fifth-instar nymph are provided to help distinguish it from other North American Rhyparochromidae. It is speculated that R. saturnius was introduced in international commerceoriginating from the Mediterranean Region, most likely Italy or nearby countries.
