Bibliographic data :

The pigment pattern is found on the cephalic and posterior shields, the parapodia and the foot.
    The anterior end of the cephalic shield is trilobate. The cephalic shield is triangular, broadest anteriorly and terminates posteriorly with a short rounded lobe.
    The posterior shield is well rounded anteriorly and terminates in two short, broad posterior lobes that are acutely pointed at their ends.
    The parapodia are relatively wide, largely covering most of the cephalic and posterior shields
    The shell is relatively thickly calcified and is a shiny white with a brownish tinge. It occupies the left third of the posterior shield. There is a broad anteriorly-directed wing and an elongate extension that is deeply imbedded in the posterior shield right to the end of the right posterior lobe.
    Etymology : The name mandroroa is the Malagasy word meaning to hallucinate. This refers to the striking, psychedelic color pattern that characterizes this species.
