also does not fit, the thorax of Eulechria rhymodes is described as "Thorax dark purple-fuscous, posteriorly narrowly pale greyish-ochreous." A good example of this is the 4th image from the left. https://boldsystems.org/index.php/Taxbrowser_Taxonpage?searchMenu=taxonomy&query=+Eulechria+rhymodes&taxon=+Eulechria+rhymodes
I still like E. rhymodes but I see a dark thorax (not obviously dark purple fuscous), but with an apparent pale grey posterior margin in several iNaturalist examples. See https://www.inaturalist.org/observations/197202432 The mapped iNaturalist distribution includes SE Queensland.
