Original description: Test nearly circular with spiral side slightly elevated towards the central part; border sharp, umbilicus deep and wide. Last chambers are indistinct on spiral side, but a small disk in the middle. Last whorl presents six to nine chambers, which are bordered on the spiral side by small, curved ledges. The chambers are strongly inflated sidewise on the umbilical side and slope towards on the umbilical side. Border formed by a sharp ledge. Surface is rough. The species is related to Rotalina ralemburgensis d'Orbigny, 1846.
