Acanthophyllia vs Indophyllia?

[ciscomania]

Can someone tell me what the difference is between Acanthophyllia and Indophyllia?

They're very similar, but scolymia indo pacific became acanthophyllia, and I am not sure but I think indophyllia used to be cynarina something. Basically I think of the whole musidae family on the scale of wiggliness. Scolymia to acanthophyllia with cynarina and indophyllia in between. The difference is mostly skeletal, but acanthophyllia can get huge where as scolymia, cynarina and indophyllia are smaller. There are external features as well, but they blur the lines. There is a good reefs.com YouTube video that compares the 3, and another solely for scolymia.

Here's an older article before the reclassification of acanthophyllia, but hopefully that sheds some light.
