Euchaetes nancyae sp. n. is described from southeastern Arizona. Although superficially similar to species of Pygarctia Grote, structural and molecular variation shows it to be most closely related to Euchaetes helena (Cassino). Adults, genitalic structure, eggs, and first instar larvae are described and illustrated. The larval host plant remains unknown. Euchaetes helena is confirmed as occurring in Mexico.
