Costasiella kuroshimae Ichikawa, 1993 has been found by us at two sites now, off Shelly's Beach Caloundra and at Flinders Reef off Cape Moreton. The specimens from Flinders Reef present with a significant and distinctive white spot on the anterior face of all the cerata, towards the tip but below the orange band (Bottom photo). The Shelly's Beach specimens, on the other hand, do not seem to possess this spot, at least not of a noteworthy size (Top photo). We will need to find more examples at different sites to draw any conclusions about this as it is considered a highly variable species in colour.
