Taxonomy of the Camponotus festinatus complex in the United States of America (Hymenoptera: Formicidae)

The taxonomic status of the six United States species comprising the Camponotus festinatus (BUCKLEY, 1866) complex is reviewed. A neotype for C. festinatus is designated and the female castes are described. The remaining five species are redescribed relative to C. festinatus. Camponotus fragilis PERGANDE, 1894 sp.rev. is revived from synonymy; C. pudorosus EMERY, 1925 stat.n. is recognized as a distinct species. Two new species are described: C. absquatulator sp.n. (California) and C. microps sp.n. (Arizona).
