Anterior prosternal lobe with a protruding 'tooth'. First segment on hind feet (metatarsomere) very elongate, especially in males.
This is an extremely common species in SA. Tepper 1887 (on p.20) was most likely referring to this species (and not Agrilus australasiae) when he wrote:
'The larvae live in the bark and splinth wood of the Golden Wattle, even quite young ones, and when present in number sometimes destroy the trees altogether, in fact they would rank among the chief insect enemies of the Wattle (Acacia pycnantha) were they not so eagerly pursued by our native insect-feeding birds'.

Adults occur on a variety of Acacia species and in SA they are particularly common on Acacia pycnantha (Golden Wattle) and A. retinodes (Wirilda), where they can sometimes be observed feeding on the foliage (phyllodes). It is known to breed in the live and dead wood of both these species and in A. wattsiana, but probably uses many other Acacia species also. Turner 2001b reported A. longifolia as a larval host plant in NSW with breeding established in dead branches.
