Systematics and Biology of the Genus Macrocneme Hübner (Lepidoptera: Ctenuchidae)

In this study, thirty species considered monophyletic and congeneric with Macrocneme maja (F.) are characterized, illustrated, and discussed. Fourteen new species are described from South America. Three names are removed from synonomy, one subspecific name is reinstated as a valid species, and nine names are newly placed in synonymy. The author summarizes biological information, and discusses and illustrates patterns of geographical distribution.
