Nannodiplax rubra (Pygmy Percher) is monotypic genus apparently confined to Australia and New Guinea, although it is quite widespread within Australia, perhaps because it seems less than picky about the type of water it likes. As the name implies, it is a very small dragonfly but not as small as Nannophya australis (Australian Pygmyfly).
This was one of my earliest encounters on the 2019 Queensland trip proper (i.e. after the first three days investigating Brisbane) and the first critter I photographed at Sippy Downs. I was lucky enough to snag a female, too. I saw only males during FNQ 2022.
