Holotype: Shell small for the genus, surface glossy, color pinkish white, most intense between the axial ribs at the periphery, back of last whorl with a faint orange flush; slender, length of aperture about 1/4 the length of the shell. Protoconch of 2 whorls, with a low carination from the start; postnuclear whorls 8. Axial ribs 7 on early whorls, increasing to 9 on penultimate whorl, obsolete on the shoulder and base but forming elongate nodes at the periphery; spiral sculpture of irregularly spaced striae, approximately 9 on the penultimate whorl, more deeply incised across the base; lip preceded by a slightly more prominent axial rib 1/3 turn back. Sinus deep, U-shaped, bordered by curved parietal callus on the inside; lip edge nearly straight, stromboid notch well marked; anterior canal short, flexed to the left and deeply notched; columella slanted to the left; parietal wall and inner lip slightly raised. Height, 12.3, diameter, 4.1 mm.

Smallest member of the genus, the polished shell varies from white to dark pink and is characterized by relatively few axial ribs forming knobs at the periphery; the spiral incisions evident, except on the shoulder. Length, 12 mm; width, 4 mm. Banderas Bay, Mexico, to Puerto Culebra, Costa Rica, 10 to 50 m.

Smallest of the Calliclavas, specimens from the same lot may be deep pink, faintly pink, or white without a trace of color. It is the only species so marked and is readily distinguished from the others.

Pacific coast of Mexico. Type Locality: Tenacatita Bay, Jalisco, Mexico. The species is evidently common off the Mexican state of Jalisco.
