Hypselodoris purpureomaculosa is considered to be very rare on Okinawa as I have seen and collected a total of four individuals over many years of diving here. The animal is quite distinctive and there are no other chromodorids found here which are apt to be confused with it.
The above featured animal is one of thirteen described species of Hypselodoris found in Okinawan waters. The thirteen species identified to date (July, 2011) are:
This attractive chromodorid was originally described by Hamatani (1995) from Japan and is also known from the Philippines.
