Sri Lanka lies on the Indian Plate, a major tectonic plate that was formerly part of the Indo-Australian Plate. It is situated in the Indian Ocean southwest of the Bay of Bengal, between latitudes 5° and 10°N, and longitudes 79° and 82°E. Sri Lanka is one of the 25 biodiversity hotspots in the world. The country has the highest biodiversity density in Asia with 27% of the 3,210 flowering plants and 22% of the mammals being endemic to Sri Lanka.

The ant fauna of Sri Lanka includes 10 of the 22 known subfamilies (Amblyoponinae, Aneuretinae, Dolichoderinae, Dorylinae, Ectatomminae, Formicinae, Leptanillinae, Myrmicinae, Ponerinae, Pseudomyrmecinae). The current species list includes 234 valid species from 63 genera.
