Hypselodoris sp. 7
Koh Tao, Thailand, 30 feet, Length approx 2cm. Photo: Mabel Fang.
I think this is an unnamed species. There are not that many black spotted species and I don't know of one with a blue mantle border and a submarginal yellow band. It has similarities to Hypselodoris placida, but in that species the black spots are regularly shaped and the blue border is submarginal. It also has similarities to the black-lined H. maritima.
Note added 31 May 2005: This is a colour form of H. maritima. See message #13910.Authorship details
