Falsimohnia Powell 1951

“Genus Falsimohnia n.g.
Type: Buccinum albozonatum Watson

This genus has a dentition of similar style to that of the Boreal genus Mohnia Friele, 1878, but on shell characters the relationship is much more in accord with Pareuthria or Glypteuthria. Both Mohnia and Falsimohnia have the central tooth with a single cusp and bicuspid laterals. The reduction of the cusps of the central tooth to a single member also occurs in the Mediterranean Chauvetia (=Lachesis Risso), and this fact no doubt influenced Martens & Thiele in their placing of Lachesis australis (1903, p. 62).

I would consider Falsimohnia as a derivative of Pareuthria in which the normal three cusps of the central tooth have been reduced to a single member. There is a parallel case in the Naticoid genus Tanea, which has a central tooth with only one cusp, whereas most other genera of the family are tricuspid. Also the operculum of Falsimohnia has a blunt terminal nucleus as in Pareuthria, whereas in Mohnia it is ovate and paucispiral.”
