TYPE GENUS. — Nucellopsis Merle, 2005 by present designation.
INCLUDED GENERA. — Nucellopsis Merle, 2005 and Pronucellopsis n. gen.
DIAGNOSIS. — Shell medium sized for family. Bucciniform shape with rounded whorls. P6 not atrophied. ADP, MP present; ABP and IP present in some species of Nucellopsis . Poorly developed axial sculpture formed by weakly lamellose varices. Posterior sinus on sutural ramp deep. D1 to D6 present. ID missing. Columellar lip usually smooth. Microstructure of three aragonite layers.
DISCUSSION
The Nucellopsinae Merle , n. subfam. includes basal taxa often erroneously attributed to the Muricopsinae (synonym of Aspellinae ) because of their biconic shape or attributed to the Trophoninae because of their weakly lamellose varices. The Nucellopsinae Merle , n. subfam. (Clade D of Winclada or Clade 47 of PAUP) includes Paleocene and Eocene species that usually share a late appearance of the primary cords (P1 to MP), rounded whorls and buccinoid shape in Nucellopsis .
