Description
Summary:Morphological (shell) and molecular examination of a large suite of specimens of pleurotomariids from around New Caledonia and the Coral Sea reveals the existence of four species in the complex of <em>Perotrochus caledonicus</em>: <em>Perotrochus deforgesi</em> Métivier, 1990 and <em>P. pseudogranulosus</em> sp. nov. live allopatrically on the plateaus and guyots of the Coral Sea; <em>Perotrochus caledonicus</em> Bouchet &amp; Métivier, 1982 and <em>Perotrochus wareni</em> sp. nov. live sympatrically - but essentially not syntopically - on the slopes of New Caledonia, Norfolk Ridge and the Loyalty Ridge. All species live in the 300–500 m interval, and together form a significant component of the mollusc fauna living on hard bottoms in the SW Pacific, with individual dredge hauls containing up to 25 specimens of <em>Perotrochus</em>.
