[koeiyabe]

Formerly included Cercyonis silvestris, now raised to full species in Zhang et al. (2022), with Cercyonis incognita as a subspecies. Zhang et al. (2023) determined that hypoglauca is a species distinct from sthenele. Zhang et al. (2023) also sequenced the holotype of damei and determined it to represent the species sthenele. It is a valid subspecies and its previous synonym mexicana is treated as a subspecies of meadii.

Formerly San Francisico peninsula, CA. None, this has been extinct a long time.
