Morphologically very similar to C. occidentalis and C. duplex, but is distributed allopatrically to the former and differs from the latter by the generally shorter length of the mid and hind femur and tibia. ( A complex discriminant function formula that partially separates the two species was used by J. Martin (Ph.D. Thesis 1966)). Specimens with the mid femur shorter than the anterior femur are likely to be C. australis.
