Description
A small chromodorid, about 5 mm in length. The body is elongate, the mantle narrow and entirely smooth. The gill consists of 5 simply pinnate plumes; the oral tentacles are small and digitate.The general body colour is yellowish white. The back bears three longitudinal opaque-white stripes: a mid-dorsal stripe extending from between the rhinophores and bifurcating posteriorly at about the middle of the body length (the two legs thus formed are incompletely united behind the branchiae), and two lateral stripes which extend from behind the rhinophores and are also incompletely united behind the branchiae. The mantle margin bears an interrupted reddish-purple band with a chrome-yellow extreme edge. Rhinophores and gills are white; the underside is white.
Distribution

The genus was transferred from Chromodoris to Goniobranchus following a molecular phylogenetic revision.References
