It is the only species in the genus Synthemiopsis and has also been placed in its own tribe, Synthemiopsini. R. J. Tillyard, who first described it, considered it intermediate between the Australian genus Synthemis and the Chilean Gomphomacromia. He had material from swamps around Cradle Mountain, at about 4,000 feet (1,200 m) altitude, and from Flowerdale Creek near Wynyard. Synthemiopsis gomphomacromioides flies rapidly over the swamps and often sits on reeds. It occurs together with Synthemis tasmanica, a similar but duller-coloured species.
