Prosoparia anormalis. This taxon was reinstated as a valid species by Lafontaine and Dickel 2009. The name is based on the original illustrations because the species was synonymized with P. perfuscaria before the associated description was published. It has crisper forewing markings than P. perfuscaria, especially the finely scalloped black pm line, the antennal pectinations are shorter, and the COI base pair sequences of the two species differ by 4%.
