Simopelta (subfamily Ponerinae) army ants are specialized predators of other ants in New World tropical forests. Although they show a striking convergence in overall life-history with the well known army ants of the subfamilies Aenictinae, Dorylinae, and Ecitoninae, the genus has been little studied. We developed and characterized nine novel microsatellite loci for S. pergandei with 2-8 observed alleles (mean: 5.2) and expected heterozygosities between 0.16 and 0.87 (mean: 0.68). Three of these loci reliably cross-amplified in a second species, S. pentadentata, with 4-8 alleles (mean: 8.0) and expected heterozygosities between 0.32 and 0.85 (mean: 0.65). These genetic markers will be useful in studying the sociobiology and molecular ecology of Simopelta army ants and in elucidating convergent evolutionary trajectories that have culminated in the army ant lifestyle.
