Bibliographic data :

The body colour is pale pink with lime green pigment all over the dorsum. The dorsal surface of the body from head to tail has series of concentric circles that are bright lemon yellow and pinkish purple inside . The number of circles varies with the size of the animal but up to fifteen
    The edge of the foot alternates transverse translucent and lime green bands, which go from head to tail
    The bases of the pink rhinophores are very close. They are densely papillate on posterior side, presenting orange colouration on the papillae. These papillae are elongate, not uniform in size and occasionally bifurcated
    The oral tentacles are pinkish, elongate and longer than the rhinophores
    The tentaculiform foot corners have a deep groove across width. They have same colour as the body and two lime green rings, the first one just below the pink tip and the second one at the midpoint.
    The cerata are arranged in up to twenty-five rows, from just behind the rhinophores to the end of the foot, and they are very close together every two rows. Some rows of cerata join over the dorsum and form an arch side-to-side with the opposite row. Each row contains 315 cerata, decreasing in size towards the foot
    Etymology : This species is dedicated to Mohamed Barnosi, grandfather of the first author of this paper
