Range extension of Heliogomphus lyratus Fraser, 1933 (Anisoptera: Gomphidae) with notes on its identification, habits and habitat

Heliogomphus lyratus is a Sri Lankan endemic dragonfly.  It is one of the rarest Sri Lankan dragonflies with only three hitherto known localities.  Apart from the faunistic records of the species, nothing much is known of its biology or ecology.  We report five new distribution localities for Heliogomphus lyratus with seven different observations.  All these new localities extend the previously known range of the species.  We also provide some notes on its field identification, habits and habitat based on our field observations.
