Abstract
Until recently, the skipper butterfly Atrytonopsis zweifeli has been known from males, and the similar A. frappenda has been known from females. Discovery and analysis of a male A. frappenda from its type locality (Distrito Federal, Mexico) and an A. frappenda–like female from near the type locality of A. zweifeli, establishes Atrytonopsis zweifeli H. Freeman, 1969 as a new junior subjective synonym of A. frappenda (Dyar, 1920).
