ABSTRACT
A new species of Fusinus from Croatian coasts of Dalmatia is described and figured. Type
material was collected off Mljet Island, Croatia, at depths of 60 to 100 m in association
with Corallium rubrum (Linnaeus, 1758), but the species was also recorded from other
localities along Dalmatian coasts atdifferent habitats and bathymetrical ranges.

El material tipo se recolectó frente a la isla de Mljet, Croacia, en profundidades de 60 a
100 m asociado con Corallium rubrum (Linnaeus, 1758), pero la especie se encontró
también en otras localidades de la costa dálmata, en habitats y profundidades distintos.
