Goniobranchus albonares (Rudman, 1990) [Chromodoris]

Click the thumbnail photos to enhance!

Goniobranchus albonares has a mantle and body with an opaque white background colour with an orange band at the mantle margin. This band is in some specimens brownish-red at the margin, diffusing into orange and then into yellow. The gills and rhinophores are translucent white with opaque white edging to the gills and rhinophore lamellae. The rhinophore clubs are relatively large for the size of the species and with their bright white edging, are a very noticeable part of the animal's shape.
Pretty similar are:
Goniobranchus verrieri which differs by the colour of the gills and rhinophores: translucent red with white edgings, and
Goniobranchus preciosus which has an outer blue line at the mantle margin, and translucent red gills and rhinophores with white edgings to the lamellae.
