Nothing is known about the biology of Mycocepurus tardus.


The worker can be recognized by the pair of promesonotal spines located in the middle of the circlet of teeth on the promesonotum. It can be separated from the other two species (Mycocepurus curvispinosus and Mycocepurus goeldii) which also have these teeth, based on several different characters. It differs from the Mexican and Central American M. curvispinosus, as the anterior pronotal spines are well developed (lacking in M. curvispinosus), and propodeal spines are straight, and directed somewhat vertically. It can be easily separated from the Brazilian and Argentinean goeldii on the basis of the distributions, and in that the inferior lateral pronotal tooth is poorly developed (well-developed in M. goeldii). (Mackay et al. 2004)
