Spurilla creutzbergi? from Jamaica

From: Ross W. Gundersen


Dear Bill:
Here is another sea slug from Jamaica. As I said in my first message, all specimens were collected from St. Ann's Bay, Jamaica, West Indies. Most specimens were collected using a light weight dredge and photographed by R. Gundersen.

Here is Spurilla neapolitana. Curved cerata and transverse markings on rhinophores. Dredged at 5m in Thallassia.

Best wishes,
Ross

Thanks Ross,
I think this is what Marcus & Marcus (1970) called Berghia creutzbergi. They described this species from a single specimen from Curacao which they describe as
Alive 15mm long, brown with white spots on back and cerata. Tentacles had brown bases and white distal halves.... [In preserved specimen ] rhinophores beset with .. tubercles on all sides ..

I suspect some of the white spotted animals from the Caribbean which have been tentatively identified on the Forum as Spurilla neapolitana [see messages from Colombia - message 1, message 2] may also be Spurilla creutzbergi but I can't see enough detail in their rhinophores. Some, such as David Behrens animal from Belize, cannot be this species because the rhinophores are clearly ridged transversely.

Clearly this is another Caribbean group that could do with some anatomical work.
