Idionyx galeatus[2] is a species of dragonfly in the family Synthemistidae.

It is known only from the Kodagu district, South Canara, Wayanad and Nilgiris in Western Ghats of India.

[4] Fraser (1936) states that most of the specimens were observed flying quite low over coffee bushes or along the borders of ferny banks.

[4][5] The species is usually found flying over torrent streams and open forest patches on mountain tops.

They fly in short circles close to ground during early mornings and late evenings.
