Une contradiction apparaît dans les données de Sars (1925) concernant la station 769 (Monaco): Lophothrix latipes est noté à cette station mais non considéré comme présente en Méditerranée (p.165, 166). Sa présence en Méditerranée orientale confirmerait sa présence dans le bassin occidental. Rose (1933 a) ne la considère pas comme présente en Méditerranée.
