Taxonomic instability

The has undergone extensive recent revision, with many synonymized and others restored from synonymy. For example, L. peruvianus and L. stali were resurrected from synonymy in 2021, while L. profundus is considered a due to lost and insufficient original description.

Wing polymorphism

Some exhibit intraspecific , with both (fully winged) and (short-winged) individuals recorded. This variation has historically caused taxonomic confusion.
