A genus ranging widely in the old world but with this being the single representative in Australia. It does look like a classic Ceriagrion, though.
During November 2019 I actually saw it in two locations – it was in three but I missed one – but only had much of a photographic chance in one and I didn’t make a great job of that. At least it was a tandem pairing so I’ve got both male and female, even if the female is a little soft in the tail. 😉 I did better in the Cairns Botanic Garden on our 2022 trip.
