Rhyothemis braganza, known as the Iridescent flutterer,[4] is a species of dragonfly in the family Libellulidae.[5][3] The genus Rhyothemis extends from Africa to the western Pacific, with five species known in Australia. Rhyothemis braganza inhabits streams, rivers and riverine pools on, and adjacent to, the coast in Queensland, Northern Territory and northern Western Australia.

Rhyothemis braganza is a medium-sized dragonfly with a wingspan of 60-85mm. On the adult, dark markings on the forewing and hindwing are of similar length and lack pale spots which appear on the similar species Rhyothemis resplendens.[4] The taxon has been assessed for the IUCN Red List as being of least concern.

Etymology

The genus name Rhyothemis is derived from the Greek ῥέω (rheō, "to flow") and -themis, from Greek Θέμις (Themis), the goddess of divine law, order and justice. In early odonate taxonomy, names ending in -themis were widely used for dragonflies. The name may refer to the irregularly banded and coloured wings of species in the genus, resembling flow banding in rhyolite.[6]

In 1890, Ferdinand Karsch named this species braganza, an eponym likely honouring the House of Braganza, the former Brazilian imperial family. The original specimen was thought to have come from Brazil.[2][6][7]
