"Lissotestella" is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Cyclostrematidae.

Distribution

This genus is endemic to New Zealand including its southern islands.

Description

The shells are small, like "Lissotesta" in shape, but more solid, and with more or less well developed spiral sculpture, ranging from fine lirae to rather strong cords. The protoconch is bluntly rounded of about one and a half smooth whorls. Typically, there is a rounded swelling behind the outer lip, and a slight ledge within the peristome, that suggests the presence of a stout operculum.
