The sacoglossan Elysia sp. 07 is not yet identified or undescribed, I call it Elysia sp. 07 to distinguish it from other species of Elysia, until I know its name.
Elysia sp. 07 is characterized by its bright green colour, by the bright blue patches, and by the minute opaque white spots on the body and on the parapodia, concentrating irregularly and forming some diffuse white patches. The tips of the rhinophores and the posterior end of the foot are bright blue.
It looks somehow like Elysia sp. 23 in IPN at page 88:
Gosliner, Terrence M., David W. Behrens & Ángel Valdés. 2008. Indo-Pacific Nudibranchs and Sea Slugs. Sea Challengers Natural History Books.
Gig Harbor, Washington. 426pp.
IPN writes "This species is bright green with opaque white markings and bright blue on the parapodia, rhinophores, and foot." The picture in IPN shows a specimen with a reddish-brown background colour. The above specimens fit the description in IPN much better, they are bright green.
It was originally posted at these websites as Elysia sp. G  Genus: Risso, 1818.
For some genera, such as Trinchesia is the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I have chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
