The two tetraliid genera are well defined, but the taxonomy of the species included in each genus is challenging because there are probably several species complexes contained therein. Colour pattern and genetics appear to be the most reliable differentiators for tetraliid species; other taxonomically reliable morphological characters are yet to be found. Both tetraliid genera are obligate symbionts of zooxanthellate (hermatypic) scleractinian corals of the genus
