This picture shows a 5 - 6 mm juvenile specimen.
Pretty similar is Thorunna furtiva which has an orange/red marginal line around the mantle edge, an orange/red line along the outer edge of the gills and an orange/red line along the anterior and posterior midline of the rhinophore clubs.
Very similar is the central Pacific Thorunna kahuna  R.F. Johnson & Gosliner, 2001 which differs according to R.F. Johnson & Gosliner (2001) "by the presence of large, visible mantle glands on the sides of the head anterior to the rhinophores and posterior to the gills in T. kahuna."
Johnson, R.F. & Gosliner, T.M. (2001) Two new species of Thorunna Bergh 1878 (Mollusca: Nudibranchia: Chromodorididae) from the Indo-Pacific.
