Range: Known only ex pisce (Queen Snapper: Nemadactilus valenciennesi) fished at 45 m deep off Cape Naturaliste, Western Australia.
Description: Shell small, oval and light with a thin structure, consisting of 1.5 protoconch and 4 convex teleoconch whorls. Protoconch rounded, grey in colour, measuring 1.1 mm in diameter. Transition protoconch/teleoconch gradual. Spire short with a deep suture. Body whorl stocky with a shiny surface. Axial sculpture consisting of dense rounded ribs, around 39 costae on the penultimate whorl, becoming very close and scarcely perceptible on the last whorl, reduced in simple striae 4 mm before the labial thickening. These ribs, conspicuous on a narrow subsutural band, disappear after a light furrow formed by a spiral row of attenuated tubercles, and become faint axial striae on the body whorl, crossed by 9 shallow spiral grooves on the anterior tip. Columella arched with 2 strong columellar plaits, adapically followed by a weak one, then by fine lirae and a small denticle just below the junction with the outer lip. Aperture narrow measuring 0.72 of the total length of the shell. Outer lip slighty crenulated by the ending of the spiral pattern.
Background colour beige, tinged by coarse axial light brown stripes and a subsutural row of quadran¬gular dark brown blotches (6 per whorl). Spiral pattern of light small dashes, sometimes punctiform, close together, tending to be grouped in zones, each containing 3 to 6 lines, giving the impression of narrow cream spiral bands, the posterior one being well defined at the anterior of the subsutural ribbed zone. Interior whitish, columellar plaits white, columella brown. Animal: Not available for study.
