Liratomina is a genus of minute gastropod molluscs belonging to the superfamily Conoidea, currently unassigned to a family. The genus is a fossil taxon, known to occur between the Oligocene and the late Pliocene, in fossil beds in Australia.
In 1944, Powell described the genus as follows:
Members of the genus range in size between in height. Liratomina and Belatomina can be differentiated due to differences in teleoconches and the presence of a paucispiral protoconch in Liratomina.
The genus was first described by A. W. B. Powell in 1942, after Powell identified that Bela sculptilis (now known as Liratomina sculptilis) had unique features separating it from its previously assigned genus. The genus was placed in the order Neogastropoda by Jack Sepkoski in posthumous work published in 2002.
Liratomina fossils have been found in the Eucla Basin, Otway Basin, and St Vincent Basin of Australia, and date to between the Oligocene and the late Pliocene.
Species within the genus Liratomina include:
