Hypselodoris festiva (A. Adams, 1861)
This weeks noteworthy species is endemic to the waters of Japan, having not been recorded elsewhere. H. festiva is distinctive. It has a deep blue body with yellowish-white mid-dorsal and marginal band on the mantle and a series of large yellowish-white spots between the two major lines. The rhinophores are red and the circular rosette of gills is white with a lavender line up the clavus of each gill. H. festiva's closet Indo-Pacific relation is Hypselodoris infucata, a species distinguishable by its broken mid-dorsal and marginal band.
Your webmaster and I chose this species to introduce an equally unique nudibranch book. It has been awhile since an author has published an entire book on a specific opisthobranch fauna. Atsushi Ono has prepared an excellent guide to Japanese opisthobranchs in his newly released Opisthobranchs of Kerama Islands.
H. festiva is a great example of one of the few species whose geographic
distribution remains restricted to a relatively small area.
