Roboastra tentaculata is charaterized by broad orange bands on its bluish-green body and by the distinctive "V" or "U" shaped anterior margin of the notum. The edge of the orange bands appears to be outlined by a thin dark line. The rhinophores and the gills are of the same colour as the body. It has well developed, grooved, dorsolateral oral tentacles.
This species was posted on 9 February 2005 at these websites as Roboastra luteolineata (Baba, 1936) [Nembrotha] because I thought it might be a juvenile or a colour morph of it.
It was described as Tambja tentaculata, and transferred to the genus Roboastra  Bergh, 1877 by Pola et al. (2008).
