Dermatobranchus phyllodes is characterized by diagonal ridges on the outer half of the notum leaving most of the central notum free of ridges, giving a leaf-like appearance.
The specific name phyllodes is from the Greek word meaning ‘leaflike: chlorophyll’ in reference to the distinctive leaf-like appearance of this species.
Let me quote Gosliner & Fahey, 2011:
"There is a series of deep dorsal ridges nearly perpendicular to the mantle edge, giving the dorsum a distinct leaf-like appearance... The ground colour of the dorsum, the oral veil, and the foot is pale green and pinkish blotches are also prevalent. There are dark green speckles and spots of various sizes scattered randomly on the dorsum.There is a U-shaped band of dark green pigment at the anterior third of the notum. The rhinophore stalk is white and the club is dark. The oral veil is opaque white with dark spots along the anterior margin and a pale orange edge. The foot margin has small dark speckles."
It is Dermatobranchus sp. 2 in IPN at page 311, and Dermatobranchus sp. 6 at Bill Rudman's Sea-Slug Forum.
This specimen was misidentified and posted on 13 February 2015 at these websites as Dermatobranchus tuberculatus Gosliner & Fahey, 2011.
I like to point out that only the specimens #1 and #10 look exactly like those pictures in Gosliner & Fahey (2011), all other specimens should better be
labeled Dermatobranchus cf. phyllodes Gosliner & Fahey, 2011, they might also be very strange colour forms of
Dermatobranchus kalyptos Gosliner & Fahey, 2011, which has a pale blue or lavender ground colour with several large patches of white and tan pigment, and some raised brown areas. Exept the picture of it in the description Gosliner & Fahey (2011), are no pictures of it online, they are misidenttified Dermatobranchus pustulosus van Hasselt, 1824.
