It is characterized by its acutely mamillose lobule sac and perianth; apical crest of the lobule sac consisting of 1–5 cells; large valve composed of 18–21 hyaline margin cells and 20–29 median cells, with a single median basal cell; and nearly entire dorsal margin of the leaf. This species is described and illustrated in detail, and its diagnostic characters and a comparison with the related species are briefly treated.
