Dear Bill,
at page 20 of "Hawaiian Nudibranchs, Hans Bertsch and Scott Johnson" is a photo "copulating pair of Plakobranchus" almost the same position as my photo shows it.

Thanks Erwin,
By coincidence I've just posted a message answering your query about the correct spelling of Plakobranchus. Sacoglossans are very interesting in their mating behaviour. Some species don't have a functional vagina and others don't seem to use it even when it is open! These species have evolved a method of "hypodermic impregnation" whereby a hardened penial stylet pierces the body wall of the partner and injects a parcel of sperm. I am not sure what Plakobranchus does.
Bill Rudman.
