See text Zealantha is a genus of fly belonging to the family Anthomyzidae.

[1] The genus was described by Czech entomologist Jindřich Roháček in 2007.

[3] The genus name Zealantha is a combination of New Zealand and Anthomyzidae.

[3] In 2021, Roháček tentatively placed a novel species found in Hokkaido, Japan, Zealantha fasciolata, into the genus due to morphological similarities, pending the discovery of males of the species.

[2] Members of the genus have been found in New Zealand and Japan.
