 But recognition of this would probably result in several other small or monotypic subgenera becoming justified, and the older "Rhombochaetodon" would be the more conveniently apply to the entire radiation.But the expanded group is of unclear relationships to species like the Speckled Butterflyfish ("C. citrinellus") and the Four-spotted Butterflyfish ("C. quadrimaculatus").These might be members of the subgenus "Exornator" – the lineages around the Spot-banded Butterflyfish ("C. punctatofasciatus") – and "C. citrinellus" certainly looks somewhat similar to these.
