Remarks. This is a quite familiar bathyal species,

although its generic position varies among researchers. Schweizer et al. (2009) discussed the taxonomy of Cibicides , Cibicidoides , and other genera including “ Cibicidoides wuellerstorfi ” based on morphology and rDNA sequence. Their results indicate that this species is not phylogenetically close to species of Cibicides but to Cibicidoides ,

which implies that “ wuellerstorfi ” should be assigned to Cibicidoides or be separated as Fontbotia following Loeblich and Tappan (1987, 1994).

Occurrence. Common in the Onogoshi, Yonahama, and Minebari formations.
