Remarks :
 Identification confirmed by Hsini Lin
This species looks like Dermatobranchus tuberculatus but there are difference in color and dispostion of the tubercles, so for the moment it's better to use the term of Dermatobranchus cf. tuberculatus
Synonymous : (according worms)
- No other name
Bibliographic data :
The widely spaced, club-shaped rhinophores are behind the oral veil. They have a series of longitudinal lamellae on the rounded club and a short apex above it. The stalk does not narrow noticeably
A light brown triangular mark may be present mid-dorsally on the anterior half of the notum.
Etymology :
The specific name tuberculatus refers to the presence of rounded tubercles on the dorsal surface of the notum that characterize this species.
