REVISED STATUS

Acromyrmex pubescens (Emery   HNS 1905). REVISED STATUS.

Atta (Acromyrmex) pubescens Emery   HNS 1905: 51. [w syntypes examined, MCSN, MHNG; Paraguay ( Balzán)] .

Acromyrmex lundi var. pubescens (Emery)   HNS . Bruch 1914: 216.

Acromyrmex lundi st. pubescens (Emery)   HNS . Santschi 1916: 386.

Acromyrmex lundi pubescens (Emery)   HNS . Kempf 1972: 13.

Fowler (1985a) described the differing habitat associations of Acromyrmex lundii   HNS and Acromyrmex pubescens   HNS , 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   HNS is covered in a dense decumbent pubescence while the integument of A. lundi   HNS is relatively bare. This difference is easiest to diagnose on the mesopleura, as the mesopleural pubescence of A. pubescens   HNS comprises overlapping hairs, while that of A. lundii   HNS is sparse and the hairs non-overlapping. Given the ecological and morphological differences in sympatry between these two forms, I elevate A. pubescens   HNS to species here.
