Remarks. A. tenera is the only species of the genus currently living in the Mediterranean. It has been reported from bathyal environments in western Mediterranean ( Bonaduce et al., 1983), including the Gulf of Naples (Aiello et al., 1996). It is also known from the Adriatic Sea, in Pleistocene bathyal sediments referred to cold environments ( Breman, 1975).

In the SML CWCP it is present only in the Mollusc Mud facies (MM) and in the Gryphus and Isidella facies (IGI).
