Notes 
From editor or global species database
Checked: verified by a taxonomic editorBiology Type of larval development: direct (non planktotrophic) denoted by paucispiral protoconch. [details]

Checked: verified by a taxonomic editorDiagnosis Shell 1.8-2.1 mm high, with protoconch of 1.75 whorl and teleoconch of 2.75 to 3.25 whorls. Protoconch covered by minute granules arranged in broad spiral bands, hardly appreciable under the optical microscope, teleoconch with a sculpture of elevated, widely separated axial ribs, minute spiral threads and of distinct spiral cords restricted to the abapical area. A diagnostic feature is the distinct spiral cord overhanging adapically the suture, continued on the body whorl. Outer lip thickened externally at a distance of the edge by a broad rim, then thinning out to a cutting edge; smooth inside. Shell entirely white, translucent.
Specimens from the Azores have a quite faint axial sculpture but another shell from the type locality illustrated by Bouchet and Warén (1993: fig. 1487) resembles the dominant morphology found on Atlantis seamount.
Alvania adiaphoros somewhat resembles the mainland species A. electa (Monterosato, 1874) in general shape and in having a strong suprasutural cord separated from the suture by a channelled interspace. It differs in lacking distinct spirals in the adapical part of the whorls, in a lesser extension of the ribs towards the abapical part, and in being less umbilicate. The protoconch is also different, the granules tending to form definite spiral threads in A. electa[details]

Checked: verified by a taxonomic editorDistribution Azores, in 360-914 m; Great Meteor, Hyères and Atlantis seamounts, very common in 280-480 m. Irving seamount, rare in 460-790 m. [details]
