Phanerophthalmus smaragdinus is characterized by the cream body, densely flecked with olive green. It has a translucent shell with a greatly expanded aperture and an outer lip that projects well above the apex. The shell is external but only about 1/8 the length of the animal and almost completely covered by the parapodia. The headshield of Phanerophthalmus smaragdinus is proportionally very small, the posterior shield and enclosed mantle cavity is an equally small remnant at the posterior end of the body.
The genus Phanerophthalmus has a remarkable resemblance to members of the family Aglajidae, and until quite recently was considered to be a member of that family. It is an herbivorous opisthobranch, closely related to the genus Haminoea, with a similar radula and gizzard plates.
The photographer Klaus Stiefel writes on this 2 specimens:"Found in the shallow waters next to mangrove roots, quite abundant in San Remigio."
This species was published on 21 June 2011 on these websites as Phanerophthalmus smaragdinus (Rüppell & Leuckart, 1828) [Cryptophthalmus],
I know since a few days that Rüppell & Leuckart (1828 - 1830) is online, see reference. This text was published in 2 parts,
the pages 1 - 22 in 1828, and the pages 23 - 47 in 1830. Bulla smaragdina appears on page/Seite 26 and on plate/Tafel XI,
that is the year must be 1830, and it was not desribed as Cryptophthalmus, I don't remember from where I got this information.
I changed it on 8 January 2016 into Phanerophthalmus smaragdinus (Rüppell & Leuckart, 1830) [Bulla].
