Shell solid, elongate, inflated and reaching 7.5 mm. in length. The color pattern consists of irregular red spiral lines, each bordered by a white line, which descend across the whorls from the suture at an angle of about 40°. The ground color is light pink or pale orange. Below the suture and at the periphery there are red (occasionally brown) patches; often these fuse to form irregular axial stripes. The red lines sometimes break up into dots on the body whorl. Between the red patches below the suture there are often white patches which are sometimes tinged with yellow. On the body whorl there may be as many as 9 of these. Whorls 6, slightly flattened at the periphery. Spire produced at an angle of 60°. Protoconch minute, white, depressed. Aperture oval. Columellar callus thick, white. Rimately perforate. Suture moderately impressed. Post-nuclear whorls smooth except for minute spiral striae. Operculum fairly thin, white. Length 3,2 – 7,0 mm; Width 2,4 – 4,8 mm;

This new species is similar to the red phase of Eulithidium pterocladicum which appears only in the vicinity of Fort Pierce on the southeast coast of Florida. It differs in reaching a larger size, and by having the subsutural patches smaller, more numerous and often tinged with yellow. From the nominate form of the species it differs in having the wavy red spiral lines which descend obliquely across the whorls.

Caribic. The Lesser Antilles from Antigua to Tobago.
