General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~4.5mm long
Anthony Paul kindly highlighted to us there's another VERY similar genus called Iridonyssus. Generally it's "fatter" with shorter legs. One of the Poecilipta has a constricted abdomen, but others don't. This isn't a diagnostic feature for the whole genus. Given this is longer & more pointed/thinner we've decided on this genus.
This specimen also looks very similar to the photo of P. smaragdinea, page 368, of "A Guide to the Spiders of Australia"
