Larsenia scalaroides Warén, 1989

( Fig. 8 G-J).

MATERIAL EXAMINED. — 100 sh., DW130.

REMARKS

The occurrence of this species, originally described from off SW Iceland in 260-300 m, is surprising, but we could not see any substantial difference in the specimens collected off NW Gran Canaria. There are other shared species such as

Ancistrobasis reticulata , Rugulina fragilis and others. New to Spanish waters.
