Descrição original:

(Breure & Vega-Luz, 2021): “shell up to 34.9 mm height, 2.44 times as long as wide, almost imperforate, the spire with slightly convex sides, rather thin. Colour of the apex black-purple fading to dark-red and yellowish on the transition to the teleoconch, which colour ranges from yellowish at the top to a multicolour at the base with brown, bluish-green and whitish hues in various intensities, crossed with one (on the spire) respectively two spiral bands (on the last whorl), with arrow-like dark-brown and whitish parts; the whitish and brownish colour ofthese bands fade vertically in an irregular way, most noticeable on the last whorl. Surface rather shiny when fresh or collected alive, the whorls with indistinct growth lines. Protoconch with a reticulate sculpture of riblets and spiral striae, which are of equal strength and form a grating pattern. Whorls 5.5, rather convex, last whorl 0.72 times the total shell height; suture slightly impressed, somewhat crenulate, slightly ascending behind the lip. Aperture compressed elongate-ovate, 2.2 times longer than wide, 0.51 times the total height. Peristome simple, somewhat sinuate above, white. Columellar margin regularly curved, white fading to deep purple on the inside of the aperture. Parietal wall with a thin, purplish callus.”
