Kanamarua adonis is a species of sea snail, a marine gastropod mollusk in the family Colubrariidae.

[1] (Original description as Conus (Aulacofusus) adonis) The small shell measures 37 mm.

The spiral sculpture consists of narrow equal flat threads (about three to a millimeter) with very narrow interspaces over the whole shell, though the interspaces are a little wider on the apical whorls and the spirals under-run there by thread-like axial sculpture, giving a somev/hat punctate appearance under magnification.

The outer lip is thickened, not reflected, with traces of liration near the inside margin.

[2] This marine species occurs in Suruga Gulf, Japan.
