Waikura is a genus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks. This genus is currently placed in the family Pyramidellidae .[1]

Shell description

[edit]

The original description by Marwick (1931) says that the genus consists of small shells that are subconical with a telescopic spire. The protoconch is heterostrophic and immersed. The sculpture consists of tubercles on the shoulders that extends axially for a short distance. There are no spiral sculpture except on the subsutural border. The surface is smooth and polished. The aperture is subrhombic with a highly sinuous outer lip that is convex below. Columella has a week tooth at the top.

Life habits

[edit]

Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are probably ectoparasites.

Species

[edit]

Species within the genus Waikura include:

Taxon inquirendum
  • Waikura chabanesi (de Folin, 1870)
