Xenuroturris also known as Iotyrris is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.[1][2]
This genus characterized by a polygonal protoconch. The anterior siphonal canal is relatively short. The sinus rib is margined.[3]
Taxonomy
The genus Iotyrris was synonymized with Xenuroturris in 2024 following a comprehensive phylogenetic revision of the family Turridae.[4] Iotyrris had originally been distinguished from Xenuroturris based on radular morphology; while species of Xenuroturris were characterized by "duplex" marginal radular teeth, those assigned to Iotyrris possessed "semi-enrolled" marginal teeth.[4]
However, molecular analyses utilizing exon-capture data demonstrated that these radular traits were homoplastic and not consistent with the phylogeny.[4] The study found that species possessing duplex teeth (such as X. olangoensis, X. kingae, and X. notata) fell into the same well-supported clade as species with semi-enrolled teeth.[4] Because the radular morphology was found to lack diagnostic value at the generic level,[5] Iotyrris was reduced to a synonym of Xenuroturris.[6]
Distribution
This marine genus occurs in the Red Sea and extends from the tropical Indian Ocean to the tropical Pacific Ocean as far east as Hawaii; also off Australia (Queensland) and Mozambique in the Western Pacific Ocean.[citation needed]
