Lobiger serradifalci from the Mediterranean

From: Bill Rudman
As background for the on-going discussion on Lobiger viridis here is some information on the Mediterranean species Lobiger serradifalci (Calcara, 1840).

Thompson (1988) gives a full description of this species. The parapodial flaps do not have secondary branches or crenulations along the edge of the flaps. There is a notch at tip of radular teeth, and Thompson describes "thorn-like lateral denticles" on the smaller teeth.. These are lost in the larger, more recent teeth.
