This species was described by Edward Meyrick in 1885 using material collected in Dunedin and named Heterocrossa cryodana.[1][2] In 1922 Meyrick synonymised Heterocrossa with Carposina.[3][4]George Hudson, in his 1928 publication The Butterflies and Moths of New Zealand, discusses this species under the name Carposina cryodana.[5]Alfred Philpott studied the male genitalia of this species in 1928.[6] In 1978 Elwood Zimmerman argued that the genus Heterocrassa should not be a synonym of Carposina as the genitalia of the species within the genus Heterocrassa are distinctive.[3] In 1988 John S. Dugdale assigned the species back to the genus Heterocrossa.[7] The lectotype specimen is held at the Natural History Museum, London.[7]
