Sthenolepis gracilior Augener, 1927 was deliberately kept out of this table due to the lack of morphological details in the original description, which may agree or disagree with Sthenolepis but to other morphologically close genera such as Horstileanira or Labiosthenolepis. Currently, Leanira izuensis and L. vulturis are junior synonyms of Ehlersileanira incisa (Grube, 1877); however, here they are considered in the table due to the past combination under the genus-group name Sthenolepis and the current unclear specific status (Hartman 1965; Cruz-Gomez 2022b).
