Fossil species

 * †Merrifieldia oligocenicus ( Bigot, Nel & Nel, 1986), formerly Pterophorus oligocenicus, from the late Oligocene–early Miocene boundary.

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. 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.
