Megalomyrmex piriana, sp.n .. can be distin­guished from M . silvestrii by the laterally produ­ced propodeal spiracles and the sculptured meta­notal groove. The latter character suggested the name piriana, meaning striped in Tupi. The meso­notum of M . piriana , sp.n cannot be distinguis­hed from the pronotum in side or dorsal view. The type series has been collected by J. & S. Peck in April. 4. 1976.
