Species Account:

        Chromodoris dianae is one of five recently described species of Chromodoris from the tropical Indo-Pacific (Gosliner & Behrens, 1998). The featured animal was named by David Behrens for his wife, Diane. The animal is rare on Okinawa as I've seen and collected only three animals as of this writing.

        Chromodoris dianae is similar to other pale blue members of the C. quadricolor complex and it is one of several bluish-colored Okinawan chromodorids with black longitudinal lines and orange or yellow on the gills and rhinophores. The two Okinawan chromodorids which most closely resemble C. dianae are C. boucheti and C. michaeli. The relatively dark medial blotch of C. michaeli and the "near figure eight" pattern of the black longitudinal lines of C. boucheti serve to separate these two animals from C. dianae.
