Known only from coastal habitats and offshore islands of Baja California ( Fig. 132D ), this species has a generalized Temnothorax habitus, save for the extremely broad postpetiole. It can be separated from most similar appearing species be the combination of the broad postpetiole and erect setae on the antennal scapes.
