was first described in Sri Lanka (Ceylon) in 1910, and this island is probably the origin of this species. Later, it was also found in the Caribbean (Cuba and Trinidad and Tobago).

A new species of Curtis, 1826 from Europe (Lepidoptera: Geometridae).

Charissa is a species-rich genus within the geometrid subfamily Ennominae, and is widely distributed in the Palaearctic and the Oriental regions; one species also occurs in the Nearctic.
