Remarks :
 Synonymous (according worms) :
- Chromodoris marginata, (Pease, 1860)
- Chromodoris verrieri, (Crosse, 1875)
- Doris marginata, Pease, 1860
- Glossodoris marginata, (Pease, 1860)
- Glossodoris verrieri, (Crosse, 1875)
- Goniodoris verrieri, Crosse, 1875
Bibliographic data :
The inner yellow orange band may be broken up into patches
The approximately 10 gills are held in a cup shape as in Hallaxa or Thorunna
The dorsum is pustulose and irregular. In some specimen, It is creamy with opaque speckling and small patches of yellow orange
It appears that no red is present in the rhinophores of Hawaiian specimens.
The mantle of this sea slug is elongately oval with a broad mantle overlap, the foot extending behind the mantle when the animal is crawling.
The underside of the mantle is white except for the red and yellow border of the mantle showing through. The foot is also white.
These species have similarity with Goniobranchus albonares and Thorunna horologia but :
- In Thorunna horologia, the marginal line thickens midway down the body. And an additional purple/bluish margin line is present around the edge of the foot
- In Goniobranchus albonares the rhinophores and gills are white.
