Leptothyra is a genus of sea snails, marine gastropod mollusks in the family Colloniidae. [2]

Contents

This genus was previously placed in the family Turbinidae.

The name Leptothyra is generally attributed to Pease (1869), and the name "Leptothyra Pease, 1869" is usually treated as a valid name for small colloniines. Although Leptothyra is a junior objective synonym of Homalopoma, the species usually treated as valid in that genus are provisionally listed in WoRMS under "Leptothyra sensu Pease, 1869", pending a taxonomic/nomenclatural reappraisal. [2]

LeptothyraJ. G. Cooper, 1867 is now considered a junior objective synonym of the genus Homalopoma Carpenter, 1864 [3]

Description

The small, solid shell has a turbinate or globose shape. The operculum is multispiral with a subcentral nucleus and concave in the centre outside. The main character distinguishing Collonia from Leptothyra seems to be the peculiar peristome of the former. [4]
