Hypoponera opacior, worker and ergatoid male.  Most ant males are wasp-like and winged, adapted for dispersing away from their home nest to mate with queens from other colonies.  But some Hypoponera males are inbreeding specialists.  These pale creatures are worker-like in appearance and mate with their sisters in the nest.
