|Maximum size: 14 mm.
Facelina sp. #4 is a distinctive aeolid with widely-spaced clusters of cerata. The

orange rhinophores have a white subapical band. The sides of the body
are marked with white and orange "lozenges" between the clusters of
This appears to be
a rare species with the few known
animals found under ledges at 5-14 m (16-52 ft) in exposed to highly
exposed rocky areas (although it may be more common on Oahu).
