Is this Hypselodoris capensis?

March 12, 2003
From: Valda Fraser

Dear Bill,
This nudibranch definately has "a discontinuous purple margin at the anterior end of the head." Could I safely say it is Hypselodoris capensis rather than Hypselodoris carnea?

Locality: Cape St Francis, Eastern Cape, South Africa
Depth: 25m
Date: Jan 2003
Size: 25mm

Thanks.
Regards,

Dear Valda,
These two species seem very dificult to distinguish externally. From the earlier discussion on the Forum, and Terry's message, I think you are probably right. Terry suggests that H. capensis doesn't usually extend as far north as Hypselodoris carnea, so also on geographic grounds, it is a good bet this is H. capensis.
Best wishes,
Bill Rudman
