Placed in the same species group as C. antipodes and C. australis, and so similar in several structural features. However, the colour pattern (while variable) is quite distinctive … and the female has a particularly broad head.

Note that the petiole is extensively yellow, although black basally and often with some red (as here). T2 has a yellow band just before the posterior margin, which extends to include the lateral margins.
