Extra details from original publication
Remarks: Rugotruncana tilevi, n. sp., most closely resembles R. ellisi, n. sp., but its keels and costellae are stronger, and its later chambers are slightly more compressed. This species is also similar to Globotruncana saratogaensis (Applin), but the latter has no costellae.
Bolli (1951, pl. 35, fig. 18) has clearly figured the costellae on the ventral side of the chambers of the last whorl of this species.
Range: Upper Maastrichtian.
