Description and habitat

It is a medium-sized dragonfly with emerald-green eyes. Its thorax is metallic green with a golden reflex. There is no humeral stripe; but an oblique citron-yellow stripe bordering the antero-lateral suture, and a similar stripe on the lower posterior border of metepimeron. Beneath the side is blackish, striped with yellow. Abdomen is black. The borders of segment 2 ventrally yellow, and also a narrow incomplete annule on the apical border. Anal appendages are black.[4]

The male is easily distinguished by the shape of its anal appendages, and the female by the unique shape of its vesicle.[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.[4]
