Remarks. This species has recently been assigned to three different genera. It is the type species of the genus Fontbotia , which was considered as a subjective sysnonym of the genus Planulina by Revets (1996). This species is assigned to the genus Cibicidoides in this study following the results of molecular phyogenetic studies by Schweizer (2006) and Schweizer et al. (2009, 2011).

Superfamily NONIONACEA Schultze, 1854

Family NONIONIDAE Schultze, 1854

Subfamily NONIONINAE Schultze, 1854

Genus NONIONELLA Cushman, 1926a

Nonionella digitata NØrvang, 1945

Figures 5.11a–c , 8.18

1945 Nonionella turgida (Williamson) var. digitata NØrvang: p. 29, text-fig. 4.

2007 Nonionella digitata NØrvang; Vázquez Riveiros and Patterson, p. 29, fig. 12.5.

Remarks. This form can be differentiated from the other species of Nonionella by its umbilical flap with long digitate extensions. The umbilical flap is much more prominent with longer extensions than that of Nonionella stella Cushman and Moyer (1930) . The digitate flap can be observed with juveniles.
