Bibliographic data :

The body colour is pearly white. The dorsal surface from head to tail has series of concentric circles that are bright lemon yellow (sometimes absent), bright grey and pearly white or pearly pink inside. In some specimens, these circles alternate with concentric circles of bright lemon yellow outside and bright grey in the centre. The number of circles depends on the size of the animal but may be up to fifteen.
    The oral tentacles are elongate, longer than rhinophores.
    Both oral tentacles and foot corners have the same colour as the body, presenting the small ochre or dark green/black spots.
    Some specimens also have bright lemon yellow colouration on the outer side of the cerata.
    Etymology This species is dedicated to Rosana Carvalho Schrödl, wife of Michael Schrödl who kindly gave us the first specimen of this species.
