Taxonomy
The genus was first described by John Edward Gray in 1850, as a subgenus, Bulimus (Laoma). Grey named Laoma leimonias as the type species.[3] In 1891, Henry Suter moved the subgenus to Phrixgnathus.[4] In the following year, Henry Augustus Pilsbry raised Laoma to genus level.[5] Phrixgnathus, formerly considered a subgenus of Laoma,[6] has been treated as a separate genus since at least 1993.[7][8] Taguahelix, described as a subgenus of Laoma in 1955,[9] was also raised to genus level in 1993.[8]
Phylogenetic analysis places Laoma within the family Punctidae as a basal group, closely related to the genus Phrixgnathus. Both genera likely diverged from Paralaoma and Punctum at least as early as the Oligocene.[10]
Distribution
The genus is endemic to New Zealand.[11]
