As in other species of this genus, workers and soldiers are strikingly different, with the latter having heads twice as long as that of workers. Queens in A. padanensis are ergatoid, with a general shape more similar to workers (Terayama et al. 1998). Only ergatoid queens have a spermatheca. The ergatoid queens of A. padanensis have fewer ovarioles than the winged queens of A. ferox.

Two of three colonies were polygynous, with two or more mated ergatoid queens laying eggs. There were less than 20 workers and a few soldiers per colony
