Camponotus substitutus is among the more commonly encountered Camponotus in open and disturbed habitats, particularly in the chaco and near the Rio Paraguay in eastern Paraguay. This ant can be distinguished from other large Paraguayan Camponotus (Tanaemyrmex) by the following combination of character states: numerous (>20) suberect to subdecumbent setae on the sides of the head in the major caste; scape of the major simple, not flattened at base; and striking bicoloration in all female castes, with gastric tergites 1-3 (=abd. tergites 3-6) bearing yellowish-white antero-lateral spots contrasting with a dark brown to black central area. Forel’s types of C. substitutus multipilis are more pilose than most Paraguayan collections of C. substitutus, but still within the range of variation of the species. As I can find no other characters that distinguish C. multipilis from C. substitutus I synonymize it here.
