Dark grey-black coloration sometimes with weak bronze reflections; elytra usually bearing two very weak ridges or 'costae'; sides of pronotum very rounded; hind tarsus in male with gibbous first segment (as in Anilara adelaidae and allied species).
Blackburn probably based his descriptions on specimens at the SA Museum collected by Tepper from Ardrossan, Nuriootpa and Cooke Plains (c. 17 km SE of Tailem Bend). Only the latter is labelled as a type. It was collected by Tepper on 5 Jan 1887 from a 'shrubby Acacia'.
Although emerged adults have been seldom encountered, breeding records and observations by me and A.M.P. Stolarski show this to be a very common and widespread Buprestid in both mallee and woodland habitats of SA. Its larval host plants are often riddled at their base with frass-filled tunnels and there is a high level of mortality with dead non-emerged adults being quite common in some populations.

Adults have been collected from a range of hosts in various plant families but do not seem to associate with the foliage of their larval host plants. On the other hand, breeding appears to be confined to shrubs of the plant family Rhamnaceae, and is concentrated in the hard, woody basal stems and upper root-stock.
