Diagnosis. When compared to N. pimana ( Fig. 9 ), N. yuccatana ( Fig. 10 ) has a more somber chalk white to pale grayish ground color and the pattern elements reduced to a few small spots and/or an interrupted median fascia. In the male genitalia of N. yuccatana ( Fig. 25 ), the distal tips of the long, curved, rodlike costa of the valva are less recurved than those of N. pimana , and the median process of the transtilla is slightly more dilated mesially.

Type. Holotype ♀, USA, Texas, Nueces Co., Nuecestown , r.f. Yucca baccata , 12 Apr 1897, C. Marlatt ( USNM).

Nycthia yuccatana has been reared from flowers, seeds, and fruiting stalks of Yucca baccata (Liliaceae) . Adults have been collected from Texas to southern California. Specimens similar to N. yuccatana occur as far south as Chiapas, Mexico, but these may represent one or more undescribed species.
