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]
