I originally posted this on Bowerbird under Prolasius - Kate Sandiford corrected it to Ochetellus with the following comment: "The ant in the first image looks as if it has an acidopore and the right profile for the formicine genus Prolasius but the lack of ocelli, concave clypeus, and short scapes rule it out. The combination of naked pupae and bean-shaped larvae places these ants in the subfamily Dolichoderinae, while the five dorsal protuberances on the larva place them in Ochetellus. Perhaps one of the lighter-coloured forms of O. glaber? See: https://www.antweb.org/images.do?genus=ochetellus&name=glaber&rank=species ."
The ants were found moving the pupae along a branch on a standing small dead tree - they were transporting them from one small hole to another.
