, revised by DuBois in 1986. Several of the species recognized by DuBois (1986) are problematic, and parts of his keys to workers and queens are unusable. Here I deal only with the two taxa recorded from California:

. In populations from northern California, however, this character shows continuous variation between these two conditions, even among queens from the same nest (the species is polygynous). Other supposed queen and worker differences disappear when intra- and interpopulation variation are taken into account. A modern systematic treatment of the
