@jb2602 Hi, I am by no means an expert (and excuse my lack of the correct terms for the parts of the beetle) but from what I can see C. bartoni has a black mark across the back of the neck, plus an additional black mark along the thorax and abdomen. See Calomela bartoni (Acacia Leaf Beetle) I personally think many have been misclassified, but I'm no expert. Hope this helps.
