Diagnosis. Adults of N. pimana are easily distinguished from those of N. yuccatana by two features of the forewing: N. pimana has a complete, uninterrupted forewing median fascia, whereas the median fascia is faint and/or interrupted in the latter; and N. pimana has a paler ocherous forewing ground color, whereas that of N. yuccatana is pale grayish. In the male genitalia of N. pimana ( Fig. 24 ) the long, rodlike, median part of the valva is rather sinuate in the distal 0.2, whereas in N. yuccatana the rod is more evenly curved. In the female genitalia, the colliculum of N. pimana is more cylindrical than that of N. yuccatana and has a distinctive thumblike process anteriorly.

Type. Holotype ♀, USA, Arizona, Pima Co., Baboquivera Mountains, August ( USNM).

Nycthia pimana has been reared from the seeds of Agave species ( Liliaceae ). Adult captures range from April through September, probably representing two broods. The species apparently is restricted to the xeric mountain ranges of the southwestern U.S. from Texas (Davis, Chisos, and Guadalupe mountains) to Lordsburg, New Mexico, Arizona (Baboquivari, Santa Rita, Chiricahua, and Huachuca mountains), and southern California (San Jacinto Mountains), south into Sinaloa and Baja California, Mexico, typically at elevations from about 4,000’ (in California) to 6,800’ (in New Mexico). In recent years it has been collected with some frequency in the lower elevations of the Chiricahua Mountains (near Portal) in southeastern Arizona.
