The "suggest a missing species" is not working at the moment. I would suggest Calomela parilis (Acacia leaf beetle), visit:

For Calomela parilis, also see ALA:

Personally I think its closer to C. bartoni than parilis. The former is the common local species.

I think it is more like C. vittata.

I agree. I had not considered this species.

No black on head, lateral on pronotum, scutellum. Black suture line does not go all the way along. Vittae band is wavy not straight.

I’m very sure this likely to be Calomela juncta & have included my thoughts below:
C. parillis has very thick & less curved elytral bands which cover most of the elytral surface area which rules it out.
C. bartoni has a vertex line & vertical pronotum mark in addition to thicker & less curved elytral bands which rules it out.
C. vittata though the elytral band is similar in size and angle of curve, I’m lead to believe that it has black shades on vertex, suture, and/or spattered colour on the punctuations of the pronotum remnant from the lines continuation from the elytra which this one doesn’t have.
I truely think the most appropriate ID for this sighting is Calomela juncta.
I’m not sure if @martinl is on here much, but I’ve tagged him in the hope that he may see we need his help with this one (in the interim I have verified it as Calomela juncta but happy to change if it needs to be).
Given this is so long ago, I’m thinking Calomela juncta may not have been a known taxon to select at the time.
@MichaelMulvaney if Martin doesn’t see my message, do you have a way to reach out to him for us?
