This is an unidentified or undescribed species of the genus Polycera. I call it Polycera sp. 01 to distinguish it from other species of Polycera.
Polycera sp. 01 is characterized by its bownish body, covered with thin white lines, most of them longitudinal, some are oblique. There are longitudinal ridges of tan rounded tubercles, which are whitish tipped. The rhinophores are dark brown, the gills are brownish-tan mottled.
The ID was confirmed by Dr. Juan Lucas Cervera Currado.
It was originally posted at these websites as Polycera sp. A  Genus: Cuvier, 1817.
For some genera, such as Trinchesia was 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.
To my knowledge are these the only pictures of this species, it is not in IPN nor at the internet!
