Dear Bill,
In September 2000, I sent photographs by Yoshi Hirano to the Forum of Elysia trisinuata. The white papillae are minute (as you can see from Yoshi's photos) but they are still readily apparent. The colouration of the Elysia sp. 11 looks much different from E. trisinuata in Japan or in Taiwan. All the specimens that I have seen of E. trisinuata are very massive or thick, not delicate or "svelt" like most other Elysia species. Also, parapodia thickenings are quite visible in Elysia sp. 11 but not in E. trisinuata. Good luck with finding a name but I do not think it is E. trisinuata, despite the way Elusia sp. 11 is holding its parapodia.
All the best,
Cordially,
Cynthia

Don't worry, I wasn't trying to 'squeeze' Elysia sp. 11 into E. trisinuata and my apologies for not including a link to the Elysia trisinuata Page and Yoshi's helpful photos. It will be great when we have easily available photos of all the named sacoglossans, as the subtleties in shape and colour are very difficult to record in words and black and white drawings.
Best wishes,
Bill Rudman
