Olivella klappenbachi is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives. [2] The species was described from specimens collected off southeastern Brazil at a depth of 610 m. [3]

Contents

Type locality

South of Cabo Frio, Rio de Janeiro State, Brazil (23°47′S, 42°10′W), at a depth of 610 m. [3]

Description

The shell is medium-sized for the genus, reaching a length of about 6 mm. It is obconic in shape with a low to very low spire and a broad, channeled suture. The shell coloration is described as dirty cream, with a white aperture and parietal callus. [2]

The parietal callus is well developed and opaque, sometimes forming a rounded projection near the end of the aperture. The pillar structure is simple, bearing a single fold at the posterior end and otherwise smooth. The protoconch is relatively large and rounded, with a blunt apex. The operculum and radula are unknown, as only empty shells were collected. [2]

Distribution

This deep-sea species occurs off southeastern Brazil, where it has been collected at depths of around 610 m. [2]

Remarks

Olivella klappenbachi is distinguished from similar species such as Olivella riosi by its more stout, whirligig-shaped shell, a thicker parietal callus, and a proportionally larger protoconch. [2]
