Merrifieldia is a genus of moths in the family Pterophoridae. It has an Old World distribution, with species known from Asia, Africa and Europe.[1]
As of version 1.1.23.125[update], the Catalogue of the Pterophoroidea of the World lists the following species for genus Merrifieldia:[1]
This species was originally described as Pterophorus oligocenicus, and its authors associated it with what was at the time the tridactyla-spicidactylus group within genus Pterophorus.[3] Although these species were transferred to Merrifieldia as a result of the 1996 revision of Pterophorus sensu lato by Cees Gielis, Pterophorus oligocenicus remained within Pterophorus until it was transferred to Merrifieldia in 2012 by Sohn et al.[3][2]
