Perinaenia
Perinaenia is a monotypic genus of moths of the Noctuidae family. It is here provisionally treated as separate from Xestia, though it seems closely related. Containing only the single species P. accipiter, its closest living relatives are not resolved and thus the genus' eventual fate depends on how Xestia is treated.
This species is known from western China, northern India, Tibet and Japan.
