Eusynthemis rentziana is a species of dragonfly of the family Synthemistidae, known as the swift tigertail. It is a slender, medium-sized dragonfly with black and yellow markings. It inhabits streams in eastern Australia
Eusynthemis rentziana appears similar to Eusynthemis guttata which is found in streams of south-eastern Australia. The genus name Eusynthemis combines the Greek εὖ (eu, "well") with Synthemis, an existing genus of dragonflies, referring to a more developed form compared with other members of Synthemis.
In 1998, Günther Theischinger named this species rentziana, an eponym honouring the orthopterist David Rentz, who recorded the species south of the Hunter River in New South Wales. List of Odonata species of Australia Wikipedia →

GBIF citizen-science records
It is estimated from how often the Swift Tigertail is recorded against all the insects logged in Lamington National Park (13 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
