Members of the genus have shells that range from ovate to ovate-elongate, without a sinuous anterior margin. Numerous fine radial ribs is a feature commonly seen in Parilimya.
Taxonomy
The genus was first described in 1899 by James Cosmo Melvill and Robert Standen, as a subgenus of Pholadomya. In 1982, a new family was erected for the genus, Parilimyidae.
Distribution
Members of the genus have been found in the North Atlantic Ocean, the Torres Strait, Japan, the western Pacific Ocean, and New Zealand. Fossils of the genus have been found in Japan and New Zealand, dating to the Miocene.
