Taxonomic remarks and comparisons.

This species is recognised based on the descriptions and figures in Bratcher and Cernohorsky (1987) and Aubry et al. (2021), and differs from its similar species, Granuliterebra bathyrhaphe ( Smith, 1875) , in having a smaller shell and two additional minutely beaded spiral cords abapical to the subsutural margin and on the lower base.

Granuliterebra Oyama, 1961
