Genus Temnothorax Mayr

Most of the California species formerly placed in Leptothorax have now been assigned to Temnothorax (Bolton 2003) . With at least twenty species in California, this is a diverse group showing wide variation in habitat and nest­site preferences. About a third of the species are arboreal. Most species appear to be generalist scavengers.
