Apsona is a genus of small-headed flies. It contains only one species, Apsona muscaria, which is endemic to New Zealand.[2] It is very similar to the North American species Eulonchus smaragdinus.[3]

A second species, Apsona caerulea, was described from Brazil by Enrico Brunetti in 1926, but its true placement is not clear.[3] In a 1957 PhD thesis by Evert I. Schlinger, Apsona caerulea was transferred to the genus Lasia.[4] Because the dissertation is considered to be unpublished according to the International Code of Zoological Nomenclature, this nomenclatural act is not valid.
