Chromodoris luteorosea from Spain

January 26, 2001
From: Alma Sánchez


Dear Dr. Rudman,
Here are two photos from southern Spain. The upper photo is of Chromodoris luteorosea (von Rapp, 1827) which is easily distinguishable by the presence of rounded and yellow dorsal spots surrounded by thin white rings, whereas in the second photo (ass3) this chromodorid? has a much more irregular pattern: the yellow spots on dorsal surface are different in size and form. Can you help me?.

Data: Bay of Algeciras (Strait of Gibraltar, Southern Spain).
UPPER PHOTO: Size: 25 mm., Depth: 26 m.
Date: April 2000.
LOWER PHOTO: Size: 30 mm., Depth: 22 m.
Date: July 2000.

Best wishes,
Alma Sánchez

Dear Alma,
I am not familiar with these Mediterranean chromodorids but the pattern is so similar that I am sure they are the same species. Apart from the colour pattern, both animals show an identical pattern of dendritic white mantle glands on each side of the body, starting from just in front of the rhinophores. If I am wrong I am sure someone will let us know.
Best wishes,
Bill Rudman
