Dear Dennis,
you make some interesting points. I agree we have to wait for the original
description. One thing: the colour pattern in C. glorioceanus is complicated
and yet it is exactly the same as in C. gloriamaris. Do you know any other
example of a colour pattern this complex (note, e.g. the paler bands), yet
shared by species from different genera? I would be surprised.
Kind regards,
Marien
