    • Senior synonym of luederwaldti: Kempf, 1968b: 408; Kempf, 1972a: 64; Bolton, 1995b: 109.
    • [Note: discussion of validity of name is under geralensis.]
  • geralensis. Camponotus (Pseudocolobopsis) macrocephalus subsp. geralensis Emery, 1920c: 36 (s.w.q.) BRAZIL (Santa Catarina).
    • Subspecies of macrocephalus: Emery, 1925b: 158; Borgmeier, 1927c: 155; Eidmann, 1936b: 96; Santschi, 1939e: 329; Kusnezov, 1952d: 212.
    • Junior synonym of macrocephalus: Kempf, 1968b: 408; Kempf, 1972a: 64; Bolton, 1995b: 101.
    • [Note: geralensis was proposed as a replacement name for Camponotus macrocephalus Emery, 1894c: 169, by Shattuck & McArthur, 1995: 122, as both this name and Formica macrocephala Erichson, 1842: 259, were at that time together in Camponotus, and the junior name was a secondary homonym. As the two macrocephalus names now occupy different genera, the replacement name is redundant.]
