Pseudopostega cretea

"Reliably identified only on basis of genital morphology. For sight identification, the brown marking that occurs midway on the posterior margin of the forewing tends to extend anteriorly and apically, whereas in the similar P. quadristrigella, this marking is a low-lying, non-extended trapezoid. Also, the frequency of melanism, seen in various degrees, is higher in P. cretea than in other Nearctic Pseudopostega species."
