Fowler (1985 a) described the differing habitat associations of Acromyrmex lundii  and Acromyrmex pubescens  , noting that the former is found in open habitats and the latter in the patchy forest “islands” that occur in the chaco savannah. The two forms are sympatric and structurally similar, both bearing elongate lateral pronotal spines that are longer than the mesonotal spines. However, these ants are distinguishable in pubescence. Much of the integument of A. pubescens  is covered in a dense decumbent pubescence while the integument of A. lundi  is relatively bare. This difference is easiest to diagnose on the mesopleura, as the mesopleural pubescence of A. pubescens  comprises overlapping hairs, while that of A. lundii  is sparse and the hairs non-overlapping. Given the ecological and morphological differences in sympatry between these two forms, I elevate A. pubescens  to species here.
