Description
Elongated body with spatulate head. Translucent body with opaque white markings comprising several longitudinal white lines on dorsum and small white dots on orange-red margin. Magenta spots and patches between dorsal white lines. Foot translucent with magenta spots and patches, and small white dots. Rhinophores distinctive with white core bearing two red bands. Gills small, held upright, red proximally and white distally.
Remarks
Small specimens are similar to several species of Thorunna, such as Thorunna australis (Risbec), recorded only from South Africa in the western Indian Ocean: it also has orange bands on the gills and rhinophores but the white markings are limited to one or two lines on the dorsum. Thorunna florens (Baba) also has similar gills and rhinophores but has purple spots around the margin as well as an orange border to the frontal margin, and it is limited to the western Pacific. Several un-named species are illustrated in Gosliner et al. (2008) but at present they are only known from few localities in the western Pacific.
