Three species in one: a revision of Clemensiaalbata Packard (Erebidae, Arctiinae, Lithosiini)

Clemensiaalbata Packard, previously thought to be a single, widely distributed North American species, is here shown to consist of three distinct, primarily parapatric species: Clemensiaalbata Packard, C.umbrata Packard, stat. rev., and Clemensiaochreata Schmidt & Sullivan, sp. n. Adults and genitalic structures of the three species are illustrated.
