Camponotus lessonai Emery. Hashmi 1973: 129.

Hashmi (1973) never saw the types of C. lessonai and subsequently excluded C. lessonai from Myrmothrix. I located Emery’s lessonai types from San Pedro at MCSN and they are nearly identical to Forel’s type of C. damocles from San Bernadino (MHNG examined). Workers of these forms are considerably darker than Mayr’s type of C. cingulatus and match several recent collections from eastern Paraguay. I have also encountered light-colored C. cingulatus in San Pedro. Whether the presence of sympatric color morphs indicates mere intraspecific variation or the existence of cryptic species is not clear. However, Hashmi (1973) considered C. damocles a junior synonym of C. cingulatus, and if one adopts Hashmi’s broad concepcion of the species then C. lessonai should also be synonymized.
