Currently, <i>Leanira izuensis</i> and <i>L. vulturis</i> are junior synonyms of <i>Ehlersileanira incisa</i> (Grube, 1877); however, here they are considered in the table due to the past combination under the genus-group name <i>Sthenolepis</i> and the current unclear specific status (Hartman 1965; Cruz-Gomez 2022b).</p>
