Heterocrossa is a genus of moths in the Carposinidae family. It is endemic to New Zealand. This genus was previously regarded as a synonym of the genus Carposina. However Elwood C. Zimmerman in Insects of Hawaii (1978, p. 797) removed Heterocrossa from synonymy with Carposina. Zimmerman argued that as the genitalia of Heterocrossa and Carposina are distinct, Heterocrossa should not be regarded as a synonym of Carposina. This was agreed with by John S. Dugdale in his annotated catalogue of New Zealand Lepidoptera.
