Abstract
A new Mediterranean species of the genus Crisilla Monterosato, 1917 (Rissooidea, Rissoidae) is described: Crisilla hiera n. sp. All known specimens are empty shells retrieved from a sample of bioclastic sand collected in a submarine cave at Marettimo Island (type locality). It is compared with the most similar congeners from the Mediterranean Sea, such as Crisilla beniamina (Monterosato 1884), C. aartseni (Verduin 1984), C. ramosorum Oliver, Templado & Kersting, 2012, C. didyme Amati & Oliverio, 2020 and Crisilla sp. (Romani et al., 2018), and from the Eastern Atlantic Ocean, such as C. ugesae (Verduin, 1988) and C. ugesae sensu Auctores. Crisilla didyme is first reported from a site different from the type locality, at Capo Palinuro (southern Tyrrhenian Sea).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
