This species was first described by Edward Meyrick in 1907 and named Gelechia acrodactyla.[3][2] Meyrick used three specimens collected in native forest in Invercargill by Alfred Philpott.[3] In 1915 Meyrick placed this species within the genus Anisoplaca.[4] In 1928 George Hudson described and illustrated this species.[5][2] John S. Dugdale confirmed the placement of this species in the genus Anisoplaca in 1988.[2] The male lectotype specimen, collected at Invercargill, is held at the Natural History Museum, London.[2]
