Abstract
Schinia immaculata, new species, is described from riparian habitats along the Colorado River in the Grand Canyon. Habitats include the shoreline, new high water dominated by tamarisk (Tamarix sp., Tamaricaceae), and old high water characterized by mesquite (Prosopis sp., Fabaceae), acacia (Acacia sp., Fabaceae), and desert shrubs. Adult and male genitalia are illustrated and compared with Schinia biundulata Smith.References
