Moelleriopsis sp.

Fig. 15C‒D

Material examined

GALICIA BANK • 1 sh.; 42°51′ N, 11°53′ W; 1110‒1125 m; 19 Oct. 1987; SEAMOUNT 1 DW108 ; MNHN .

Remarks

A single shell from DW108 can be assigned to the genus Moelleriopsis from the broadly umbilicate shell with spiral cords circling the umbilical area. However, the last whorl increases in diameter much more than most of the species possibly present in the area (the Mediterranean Moelleriopsis messanensis (Seguenza, 1876) ; M. richardi (Dautzenberg & H. Fischer, 1896) and M. normani (Dautzenberg & H. Fischer, 1897) , both described from the Azores; M. atlantis Hoffman, Gofas & Freiwald, 2020 and M. meteorminora Hoffman, Gofas & Freiwald, 2020 , both from South Azorean Seamount Chain). Moelleriopsis gritta Hoffman, 2020 has a similar coiling but has a distinctive subsutural keel whereas this shell has such a keel only poorly expressed on the first part of the first teleoconch whorl. It probably belongs to an undescribed species but more material is needed before naming it.
