Chromodoris from Guam

September 4, 1998
From: Clay Carlson

Bill, Do you have any ideas on the attached scan? We picked up the animal in Palau some 20 years ago and just recently found it in Guam. The scan is of a 13mm specimen, On this the marginal color band is a golden brown. The more recent animals from Guam had a more orangish marginal band as well as a hint of purple on the rhinophore lamella and on the oral tentacles. The submarginal purple/reddish spots carried through the mantle to appear as red spots on the underside. Chromodoris lata?

Thanks for any help or suggestions you can offer.

Your animal certainly looks like a chromodorid. My suggestion would be a colour form or a close relative of Chromodoris decora. It is one of the few species with such a transparent edge to the mantle. If the Y-shaped mark on the back was extended to cover the whole of the back it would be very similar to your species. Just a guess. I don't think we will ever know what Risbec's Chromodoris lata is but my understanding of his description is of an opaque white mantle with a thin red border. Any one else with ideas? .. Bill Rudman.
