Some Coralliophilinae from the deep waters of the north Atlantic Ocean and the Mediterranean Sea, with a description of a new species from the Meteor Seamounts and the rediscovery of Pseudomurex perfectus

This publication presents a conchology-based systematic revision of selected deep-water Coralliophilinae (Muricidae) from the North Atlantic Ocean and Mediterranean Sea, emphasizing taxa historically confused with Coralliophila squamosa and related morphotypes. The study is based on comparative shell morphology of historical expedition material and curated museum specimens, interpreted using a standardized spiral-cord homology framework (after Merle) and detailed assessment of teleoconch sculpture, axial ribbing, infrasutural ramp structure, and siphonal canal morphology. The revision refines taxonomy, distribution, and bathymetric ranges and stabilizes nomenclature through reassessment of historical type concepts. Treated taxa include Coralliophila squamosa (Bivona & Bernardi, 1838) as a shallow-water reference, together with C. ruderata (Sturany, 1896), C. monterosatoi (Locard, 1897), and C. basileus (Dautzenberg & Fischer, 1896). The long-misapplied name Coralliophila lamellosa (Philippi, 1836) is formally replaced by Coralliophila oblita Garrigues, 2025 (nomen novum). The paper also describes Coralliophila meteorensis Garrigues, 2025 from the Meteor Seamounts (southern Azores) and clarifies the identity and generic placement of Pseudomurex perfectus Fischer, 1883, distinguishing it from Babelomurex sentix; additional discussion addresses the morphology and taxonomic interpretation of Babelomurex benoiti (Tiberi, 1855). Material examined derives from numerous historical and modern oceanographic campaigns (TRAVAILLEUR, TALISMAN, HIRONDELLE, METEOR, SEAMOUNT, BIAÇORES) and institutional holdings from MNHN, NHMW, IRSNB, USNM, and other collections. No molecular dataset is presented; taxonomic conclusions are based on comparative shell morphology, type material evaluation, and homology-based sculpture interpretation. The work establishes a clarified morphological framework for deep-water Atlantic–Mediterranean Coralliophilinae and provides a stable baseline for future integrative (morphological + molecular) revision of bathyal and seamount faunas.
