Diagnosis. Shell medium to large, white; sculpture of strong radial ribs; lateral teeth 3 pairs; marginal teeth lacking.
Biology. The species of Niveotectura have the lateral teeth with blunt tips suited for grazing on coralline algae.
Remarks. There are two living species, the type species, which is a relatively large species common in shallow water of the northwest Pacific, and the smaller Niveotectura funiculata, occurring offshore in the northeastern Pacific. The genus was treated in detail by Lindberg and Marincovich (1988), who described a fossil species from Alaska.
