Abstract
Arene lychee sp. nov. is described from Canopus Bank, a seamount located ~190 km off Fortaleza, Ceará, NE Brazil (02°14’25”S, 38°22’50”W), based on shell morphology. The species is characterized by a large, trochiform shell; color ranging from intense reddish to white (darker on spiral cords, lighter at base) with a yellow apex; sculpture of 3‑8 wide spiral cords with large scale-like spines; cords separated by deep interspaces with similar width, and interspaces sculptured by closely-packed, thin axial growth lines.
Highlights
The family Areneidae has been recently erected to remedy nomenclatural issues and to reflect recent molecular phylogenetic hypotheses of relationships within the Vetigastropoda (Williams et al, 2008; McLean, 2012)
Canopus Bank is a seamount located ~190 km off Ceará state, NE Brazil (02°14’25”S, 38°22’50”W, ca. 50‐600 m depth), which harbors an impressive diversity of invertebrate species
We formally describe a new species of Arene from Canopus stemming from a broader review of the local vetigastropod fauna (Cavallari & Simone, unpublished data)
Summary
The family Areneidae has been recently erected to remedy nomenclatural issues and to reflect recent molecular phylogenetic hypotheses of relationships within the Vetigastropoda (Williams et al, 2008; McLean, 2012). As it is currently understood, the family exclusively accommodates species previously belonging to Liotiidae Gray, 1850. Studies on sediment samples from Canopus collected in 2005 have revealed a remarkable number of new taxa This includes 17 new gastropod species belonging to 12 different families, most of which were described based on empty shells We formally describe a new species of Arene from Canopus stemming from a broader review of the local vetigastropod fauna (Cavallari & Simone, unpublished data)
