This fits Barnard's description of Dendrodoris kalkensis very well. Gosliner thinks it is probably the same as Dendrodoris caesia (Bergh, 1907) but Bergh's description of a single preserved specimen is to me unidentifiable. [See my comments below]. However since Gosliner has already began using D. caesia I will continue that usage. See message below.
Background colour of mantle cream to reddish with reddish bown specks, sometimes aggregated into patches scattered all over mantle except around the edge which is translucent white with scattered blue spots, sometimes quite large, and sometimes small and more numerous. Gills salmon with bluish spots, rhinophore clubs reddish brown with dark bluish band near white tip. Mantle edge thin and frilled. Relatively large growing to 50mm.
