Protaeolidiella atra from Indonesia

April 1, 1999
From: Lindsay Warren

Dear Bill
Please find attached an illustrationby Richard Smith of an opisthobranch found in the Tukang Besi Islands, SE Sulawesi last year during the research for Operation Wallacea. Unfortunately it died and started to decompose before being able to photograph it.  The specimen was, however, preserved.

Length: 2.3 cm. The long tapering body was a dark chocolate brown / black with off striking white central line on the notum.  Along the sides were sets of three cerata with white tips.  It had quite long oral tentacles also white tipped.  It was found at a depth of 5 m on dead table coral rubble covered in algae.

Any thoughts as to what it might be?
All the best
Lindsay

Dear Lindsay,
This looks like Protaeolidiella atra which I have found in East Africa and eastern Australia, and was originally described from Japan. Its black colouration is rather unusual in aeolids, and it has some rather interesting anatomical modifications.
Best wishes,
Bill Rudman.
