Biology The type of larval development is not known from direct evidence, but is inferred to be intracapsular from similarity of the larval whorls with those of Cerithiella (see Bouchet and Warén, 1993). There is a multispiral protoconch, but no clear separation protoconch 1/protoconch 2 nor protoconch 2/teleoconch. [details]Diagnosis Shell up to 6.8 x 1.4 mm, turriculate, solid, white, with 12-15 whorls. Protoconch ca. 2.5-3 whorls, with maximum diameter 0.75 mm, the nucleus quite sunken in the following whorl, resulting in a very blunt apex; protoconch whorls strongly and evenly convex, sculptured with strong and elevated, sharp, widely spaced ribs starting on the very first whorl, slightly oblique on the first and second whorls, still more oblique on the third. Teleoconch whorls sculptured with quite strong, slightly oblique ribs on which there is a subsutural and a suprasutural bulge, separated by a broad depression; the suprasutural bulges bordered adapically by a faint spiral line. Body whorl hardly narrowing; its abapical surface smooth and circled by a faint keel on which the ribs terminate. Aperture with a continuous, moderately flaring peristome. Siphonal canal moderately long, narrowing towards outer opening, inside with columellar and labial lamellae set widely apart. Anal canal similar in size and shape to the siphonal, moderately curved, pointing sidewards.
Trituba fallax Gofas, 2003, from Hyères seamount, is similar in teleoconch sculpture but grows larger, has a proportionally much shorter anal canal and has the first protoconch whorl more protruding, making the apex not so blunt. [details]
