Taxonomic remarks and comparisons.
This species is recognised based on the descriptions and figures in Smith (1879 b), Yokoyama (1927), and Robba et al. (2004), specifically in having a high-spired, claviform shell with the sculpture of nine broad and low collabral ribs fading away shortly before the subsutural cord and overriding spirals, three closely set spiral cords: adapical, peripheral, and abapical cords, and a weaker more adapical one on the penultimate whorl, resulting in a total of 14 spirals occurring along the body whorl. This species is the type species of Pseudoetrema (Oyama 1953).
