Description
''Coryphellina marcusorum'' has a mainly translucent pink or orange body colour.
The elongate rhinophores, foot corners and cerata are tipped with opaque white (or sometimes opaque yellow), with a broad, purple band beneath. The posterior face of the rhinophores may have up to one hundred papillae.
The oral tentacles are elongate and thin, and are longer than the rhinophores.

This species is very similar in colouration to the recently described African species ''
Coryphellina arveloi''.
A comparison with other Flabellinidae species from Mexico is given in the description of ''
