Discodoris atromaculata? from Puerto Rico
March 14, 2002
From: Joseph Millevolte
Please correct me if I am wrong but I believe I saw a Discodoris atromaculata off the southwestern coast of Puerto Rico, near the village of Parquera. I made the sighting at a depth of 25m on a coral reef. The specimen was about 40mm in length, oval in shape, almost round and about 4mm thick. The color was very bright white with ink black spots distributed on the mantle. The black spots were about size of the medium size spots on the specimen displayed in second photo and were of uniform size. Also, the spots appeared to be raised slightly giving the mantle a bumpy texture. I am sorry I didn't make a note of what substance it was on, or any other pertinent observations, as I was quite low on air at the time of sighting.

Millevolte, J., 2002 (Mar 14) Discodoris atromaculata? from Puerto Rico. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/6355Dear Joseph,
Without a photo it's a bit of a guess, but one possibility is Phyllidiopsis papilligera Bergh, 1890 which unfortunately I don't have a photo of. There is a good one in Paul Humann's book [p243]. It is white with large rounded black spots, and scattered white tubercles. I don't know of D. atromaculata been reported from the Caribbean. It is of course possible that it does occur there, but without a photo or specimen there is no way of confirming it.
Best wishes,
Bill Rudman
