Goniobranchus fabulus  Soong & Gosliner, 2022 has been recently described, published 15 January 2022, it is charactererized by the solid cream/white
mantle, except of the marginal bands which are just like those of Goniobranchus preciosus (Kelaart, 1858) [Doris]: an outer pale blue, then
brownish red, then orange/yellow, and an inner white. The gills and rhinophore clubs are translucent red with pigmented white edging to the lamellae.
Some pictures were posted at these websites as Chromodoris preciosa (Kelaart, 1858)[Doris],
picture #1 on 4 January 2012, and picture #2 on 3 May 2012.
Pretty similar are:
Goniobranchus preciosus which has red pigment on the mantle,
Goniobranchus verrieri which lacks the outer blue line,
Goniobranchus albonares which differs by white gills and relatively large white rhinophores, and by an orange marginal band
Goniobranchus sinensis which differs by dark red to black gills and rhinophores, and
Goniobranchus trimarginatus which differs by white gills and rhinophores.
