Sri Lanka

The Sri Lanka ant fauna has recently come into better focus through contemporary research by Dr. Ratnayake Dias (1, 2) and her colleagues. The most recent faunal list (Dias et al. 2020) brings together Dr. Dias' extensive knowledge and the incomparable database of ant occurrence records from [https://antmaps.org/? Ant Maps]. The many myrmecologists that have contributed to our current understanding of Sri Lanka's ant fauna are noted in the references provided in the 2020 Zookeys publication and Ant Map's specimen records.
