This is one of the larger species of Zafra, with shells 3.8 to 4.6 mm long and having up to 5 teleoconch whorls. The shell is biconic, but has a taller spire than other Zafra species. It is white, overlain by tan or brown over the middle of each whorl, and covered by round white spots in a mesh-like pattern. The columella has a distinct raised ridge internally, and the labial edge is denticulate. As in most species, there is a spiral subsutural groove intersecting the axial ribs, producing a beaded ridge below the suture. The protoconch is white or brown, with a midline spiral thread on the last whorl and 2.75 to 3.25 whorls.
