Xenuroturris kingae
Xenuroturris kingae is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.
Taxonomy
The species was known also as Iotyrris kingae. The genus Iotyrris was synonymized with Xenuroturris in 2024 following a comprehensive phylogenetic revision of the family Turridae. 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.However, molecular analyses utilizing exon-capture data demonstrated that these radular traits were homoplastic and not consistent with the phylogeny. The study found that species possessing duplex teeth fell into the same well-supported clade as species with semi-enrolled teeth. Because the radular morphology was found to lack diagnostic value at the generic level, Iotyrris was reduced to a synonym of Xenuroturris.
