Description

This genus was introduced by Paul Bartsch in 1941 to accommodate species with a distinct anal sinus and a protoconch sculptured with numerous fine threads, that were otherwise similar to the species in the genera Oenopota Moerch, 1852 and Propebela Iredale, 1918. The shell has an ovoid shape and is short and stubby. The whorls of the teleoconch are strongly tabulatedly shouldered and lack a keel at the angulation of the shoulder. The axial ribs show up strongly between the shoulder and the periphery, but disappear at the base of the shell. The spiral sculpture consists of incised lines on the spire and threads on the columella. The aperture is pear-shaped, decidedly channeled anteriorly and shows a feeble sinus at the shoulder.[2]

Grammatical gender

The grammatical gender is feminine, as composed with the Greek noun τομή, an incision (gender: feminine). However often treated as neuter following Philippi (1836: 165, footnote) and others view of treating Pleurotoma as neuter. .[1]
