General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Very similar in appearance to A. lignicolor, but larger insects along with heavier/longer spines on the side of the pronotum. The scutellar spine (the body armour at the back of the body where the wings start, that curls up slightly and has the pale patch on it) appears to be thicker with these that A. lignicolor.
