Rediscovery of Macromia flinti with observations on the female and new locality records (Odonata: Macromiidae)

Macromia flinti Lieftinck, 1977, is an endemic dragonfly in Sri Lanka and one of the rarest known odonates in the country. Originally described based on a single specimen collected in 1970, it had not been reported in the past 50 years and thus was considered a globally Critically Endangered Species (IUCN), possibly even extinct. Here we report the rediscovery of the species based on a female specimen observed in the hand and multiple other field observations recorded with photographs. We also provide a summary of all known observations, the first photographs of the species in life and a description of the female, as well as notes on the species identification, its distribution, and natural history.
