Pseudorhaphitoma Explained

Pseudorhaphitoma is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae.^[1]

Description

This genus was originally described by Boettger as a section in the genus Clathurella.

The small, thick, monochrome brown or white, elongate shells are claviform. They contain 6 - 7 whorls. The prominent and continuous axial ribs are moderately strong. They are crossed regularly by numerous, fine spiral lirae, producing granular or transverse plicules. The aperture measures about a third of the total length. The weakly notched siphonal canal is narrow and shallow. The sharp outer lip is denticulate on the inside and usually shows a particularly strong tooth close to the well-cut anal sinus. The columella occasionally carries 1-2 denticles.^{[2] [3]}
