Hi danswell, Myrmecia nigrocincta is a very distinctive ant with brown and black patches and virtually no records around the southern tablelands - mainly found further north. Around the ACT there are several species of jumping jack ants which all used to be the species”pilosula” but now are split up and need a microscope to ID to species, so they get grouped together in CNM under “Myrmecia pilosula group”.
