Remarks :

This species is discribeb only from Western Pacific and it's very difficult to identified Dermatobranchus only by photo, so until I have a confirmation by a specialist I prefered to call this species Dermatobranchus cf. phyllodes
    Synonymous : (according Worms)
               - No other name

Bibliographic data :

The widely spaced rhinophores are situated behind the oral veil. They have a series of longitudinal lamellae on the rounded club. The stalk does not narrow noticeably
    There is a U-shaped band of dark green pigment at the anterior third of the notum
    Etymology : The specific name phyllodes is from the Greek word meaning ‘leaflike: chlorophyll' in reference to the distinctive leaf-like appearance of this species' dorsum
