Species Account:

        Durvilledoris lemniscata is considered to be very rare on Okinawa as I have seen and collected only two animals over a period of many years of diving here. D. lemniscata is one of three species of Durvilledoris found to date (April, 2005) in Okinawan waters; the other two species are:

        Both specimens of D. lemniscata were found together during a daytime SCUBA excursion; they were discovered beneath a slab of coral rubble as it was overturned in an area of mixed silty-sand and strewn coral rubble. The second individual illustrates a bit of variation from the above featured animal. This second animal closely resembles the one pictured in Gosliner (1987) and Gosliner points out that Berg's description has " . . . a central white band with paired, yellow lateral bands. In Berg's specimen there was a central yellow band and lateral white bands."

        There are no chromodorids currently found on Okinawa which are apt to be confused with this unique appearing, attractive little dorid.
