Taxonomic revision In 2022, the species Eurema brigitta was split through phylogeographic pattern of by comparing Afrotropical, Malagasy and Oriental-Australian populations using the mitochondrial cytochromec oxidase subunit I marker. After the taxonomic revision, Afrotropical and Oriental-Australian populations were separated by the Indian Ocean and dry habitats on the northern coasts. Therefore now the Oriental-Australian populations into a separate species, Eurema drona.
