Updating ID to agree with Reiner on iNat. @JanHartog if you get an ID from iNaturalist, it's useful if you can mention that on here. Thanks! :-)

By location, it is most likely to be Eusynthemis tillyardi, based on the distributions on iNat, but we can't see the key features to definitely differentiate between it and E. guttata.

@JanHartog I spent quite a long time comparing against both A. obscura and A. multipunctata. It's hard, I will agree, to differentiate with teh one angle and it unfortunately being a further away shot.

The defining feature is "Anterodorsal spots on abdominal terga 3 and 4 generally much reduced or absent, and on 5-7, lacking". vs for multipunctata: "Anterodorsal spots on abdominal terga 3 and 4 generally well
developed, and on 5-7, usually detectable"

To me, there's some hints of maybe 'reflections' in those spots on 6 and 7 and that's it. 4 there's maybe a reflection, or maybe it's something just greatly reduced from the size of 3, which fits more with obscura.

The terga numbering of the abdomenal sections is listed here: http://azdragonfly.org/external-anatomy.

To get an idea of what I'm looking at, compare multipunctata: Austroaeschna multipunctata (Multi-spotted Darner) and obscura: https://inaturalist.ala.org.au/observations/202008587 looking at those abdomenal segements. The top view is the easiest to pick it up first.

Is there reasons you're thinking multipunctata?
