Genera within the family Modulidae include:

    Aplodon Rafinesque, 1819[4][5]
    Conomodulus Landau, Vermeij & Reich, 2014[6][7]
    Indomodulus Landau, Vermeij & Reich, 2014[6]
    † Laevimodulus Landau, Vermeij & Reich, 2014[6]
    † Modulostylina Bandel, 2006 - with the only species Modulostylina waageni Kittl, 1884 - from Late Triassic[1]
    Modulus Gray, 1840 - the type genus of the family Modulidae[4]
