Notes 
From editor or global species database
Checked: verified by a taxonomic editorBiology 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]

Checked: verified by a taxonomic editorDiagnosis Shell up to 5.4 x 1.3 mm, turriculate, solid, white, with 10-13 whorls. Protoconch ca. 2.5-3 whorls, with maximum diameter 0.6 mm, the nucleus quite protruding; protoconch whorls convex, sculptured with strong, thick ribs, almost axial on the first and second whorl, more oblique on the third whorl.
Teleoconch whorls sculptured with quite strong, blunt, slightly oblique ribs, very slightly swollen towards their subsutural and suprasutural parts, and depressed in between; the suprasutural swells are more distinct and bordered adapically by a very faint spiral line. Body whorl slightly narrowing, with ribs attenuated or absent; its abapical surface smooth and circled by a strong keel on which the ribs, if any, terminate. Aperture with a continuous, moderately flaring peristome. Siphonal canal moderately long, narrowing towards outer opening, inside with columellar and labial lamellae coming very close together. Anal canal similar in size and shape to the siphonal, moderately curved, pointing sidewards.

Trituba fallax Gofas, 2003, sympatric on Hyères seamount, is larger, has a non-constricted body whorl, has constricted ribs and a distinct spiral line bordering the suprasutural knobs on the ribs.
