Mauroceras sandwichense View in CoL — Vannozzi 2019a: 60 and synonymy therein.
TYPE MATERIAL. — Holotype. Hawaii • dd; Hawaii; MNHN-IM-2000-24904 figured by Pizzini et al. 2013: fig. 15G .
TYPE LOCALITY. — Pacific Ocean, Hawaii.
MATERIAL EXAMINED. — Mayotte • 1 dd juv; Mozambique Channel , W Mayotte, BIOMAGLO Stn DW4854; 12°56’S, 44°58’E; 455-465 m depth; 4.II.2017; MNHN GoogleMaps .
DISTRIBUTION. — Indo-West Pacific, recorded from Red Sea, Mayotte and Hawaii ( Kay 1979; Blatterer 2019; Vannozzi 2019a).
DIAGNOSIS. — Shell small for the genus. Shell tubular, arched, slightly but clearly twisted in ventral view. Dorsal and ventral sides of the tube evenly arched. Septum slightly protruding, with a sharp dorsal mucro, slightly rotated toward the right side. Aperture simple, oblique. Early teleoconch coiled, trochospiral, widely umbilicated, starting to uncoil after about 1 whorl. Sculpture of slightly wavy collabral ribs in the early teleoconch, fading with teleoconch growth and disappearing in the adult stage. Transition to the adult stage rapid. Protoconch planorbid of 1. 5 whorls. Adult shell length 2 mm.
REMARKS
A single, rather worn juvenile stage was found in the examined material. This species shows a characteristically tightlycoiled early teleoconch that readily distinguishes it from the congeners ( Blatterer 2019; Vannozzi 2019a).
