Berthella martensi from Mauritius

From: Marina Poddubetskaia
Dear Bill,
I found this nice notaspid in Mauritius. It was in walk in an open area. Could you help me to identify it, please. Is it a species of Pleurobranchus? Which are the distinguishing characteristics of the genus Pleurobranchus?
As you could easily see, this animal was damaged on the left side of the head (rhinophore + oral tentacle). At the beginning, I thought the black tip of the right oral tentacle was an abnormality, but finally I believe this species has oral tentacles naturally tipped with black.
Pereybere, Mauritius, Indian Ocean. Site: Grand Aquarium. Depth: 11m. Size: 35-40mm. October 16, 2002

This is another colour variant of Berthella martensi. Concerning the distinguishing features of Pleurobranchus, I am in the process of preparing some keys to add to the Forum to help identify the major opisthobranch groups. If you can wait a little while, the genera of the Notaspidea will definitely be included.
Best wishes,
Bill Rudman
