Distribution edit
This species was described from Isla San Diego, Baja California, Mexico. Coryphellina marcusorum is thought to occur in two disjunct populations in the waters of central and south America: one group on the west coast of central America in the eastern Pacific Ocean[4] and as far east as the Galapagos Islands[2] and the other on the east side of the continent in the Caribbean Sea and in the western Atlantic Ocean down to Brazil.[5]
Description edit
Coryphellina marcusorum has a mainly translucent pink or orange body colour.[4] 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.[5] The oral tentacles are elongate and thin, and are longer than the rhinophores.[4]
The maximum recorded body length is 25 mm[6] or up to 30 mm.[4]
This species is very similar in colouration to the recently described African species Coryphellina arveloi.[5] A comparison with other Flabellinidae species from Mexico is given in the description of Orienthella fogata.[4]
