Description

In the original description, Powell described the species as follows:
The holotype of the species measures in height and in diameter. The species has a slightly larger and less massive shell compared to Zemitrella choava, as well as a thin outer lip and a relatively longer and narrow aperture. The neck of base of the shell is more deeply contracted than in Z. choava.

Taxonomy

The species was first described by A.W.B. Powell in 1934. The holotype was collected by Powell in August 1933 from east of Cape Runaway in the Bay of Plenty Region, and is held by the Auckland War Memorial Museum.
