Ichikawa, M. 1993. Saccoglossa (Opisthobranchia) from the Ryukyu Islands. Publications of the Seto Marine Biological Laboratory, 36: 119-139. No oral tentacles are present. From the eyes backwards, including the bases of the rhinophores, the head is covered by small, iridescent, green dots. This colour pattern continues onto the cerata, which are arranged in 7-9 rows. The cerata are green with white tips which are dotted with many iridescent spots. The ventral foot is also fringed with such iridescent dots.
