Remarks. The specimens in this study clearly resemble those illustrated by Loeblich and Tappan (1955) and Holbourn et al. (2013) in possessing an umbilical boss that was not illustrated by Brady et al. (1888). Although the genus Cibicidoides is placed under the family Parrelloididae by Loeblich and Tappan (1987), it is assigned to the family Cibicididae in this study following Schweizer et al. (2009)
