Fernández (2004) - Besides the original description, Wheeler (1922c) provided some notes of the female and male of this species, recorded from French Guiana and Brazil. He pointed out that “the males were found to be variable and Santschi was not sure that they belonged to the same species as the female”. This recurring problem has arisen from the tendency of earlier myrmecologists to describe any sexual form alone, without reference to the associated workers. The result has been species names based on only females, males or both; these will continue to confound the species lists until nest series taken in the field make it possible to match up definitively the sexual forms with their respective workers.
