Description This species is translucent pinkish-white with a magenta submarginal line on the mantle. On the back foot it has two dark purple lines. The rhinophores have translucent pink stalks and orange-red clubs while the gills are orange-red with translucent pink bases. There are prominent, opaque-white mantle glands around the posterior margin of the mantle and, occasionally, in front of the rhinophores which help distinguish it from the very similar Thorunna daniellae.Pittman, C. & Fiene, P., 2018.
