Originally described from New Caledonia as G. joubini it was later reported from Japan as
Goniodoris glabra Baba, 1937. It has also been recorded from Hong Kong (Rudman & Darvell, 1990 as G. glabra) and the Great Barrier Reef (Marshall & Willan, 2000 - as G. joubini). There is a good painting in Baba (1949) [Opisthobranchs of Sagami Bay].

The mantle and body are dark brown with white specks. There are some larger white or cream patches which often have yellow centres. There is a broad translucent band around the mantle edge which is sometimes spotted with yellow and dark brown (not here), Grows to about 20mm long alive. See message below for Risbec's original colour illustration.

See Scott Johnson's message suggesting Goniodoris aspersa Alder & Hancock, 1864 is the same species, and so the earliest name.
