Revision of the North American genera Tetracis guenée and synonymization of Synaxis Hulst with descriptions of three new species (Lepidoptera: Geometridae: Ennominae)

Abstract

The genus Synaxis is synonymized with Tetracis. The thirteen North American species in genus Tetracis (some formerly in Synaxis) are discussed, including descriptions of three new species from western North America: Tetracis australis, T. montanaria, T. pallidata. Two additional species, "Synaxis" triangulata and "S." brunneilinearia are excluded. A key to species, descriptions, check list, illustrations of adults and genitalia, and distribution maps are included. The formerly presumed lost types of the taxa aurantiacaria, cervinaria, and jubararia were located and are illustrated. Copyright © 2010 Magnolia Press.
