 These could use the names "Lepidochaetodon", "Megaprotodon" and "Rabdophorus", and there is one unnamed group containing the Three-banded Butterflyfish ("C. robustus") and its relatives.But the monophyly of the "Lepidochaetodon" group is not fully established; it is both unclear whether "Rhombochaetodon" is a lineage distinct from "Exornator", and whether "Lepidochaetodon" is indeed closer to these than to any other "Chaetodon", particularly to some lineages otherwise placed in "Megaprotodon".
