Biology:Laoma
Laoma is a genus of land snails belonging to the family Punctidae.[1] All known members of the genus are endemic to New Zealand.
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.[2] In 1891, Henry Suter moved the subgenus to Phrixgnathus.[3] In the following year, Henry Augustus Pilsbry raised Laoma to genus level.[4] Phrixgnathus, formerly considered a subgenus of Laoma,[5] has been treated as a separate genus since at least 1993.[6][7] Taguahelix, described as a subgenus of Laoma in 1955,[8] was also raised to genus level in 1993.[7]
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.[9]
Distribution
The genus is endemic to New Zealand.[10]
