I'm not sure this matches the iNaturalist examples:- https://www.inaturalist.org/taxa/1353287-Labdia-argophracta/browse_photos See also here:- https://bold-au.hobern.net/specimens.php?taxid=326537 https://bold-au.hobern.net/specimens.php?taxid=372900
I still lean towards M. euryleuca. It has the shaggy white front leg - in M. desmotoma it is b&w striped. I think the markings match better too. https://inaturalist.ala.org.au/observations?preferred_place_id=6744&quality_grade=research&taxon_id=699634 https://inaturalist.ala.org.au/observations?place_id=6744&preferred_place_id=6744&quality_grade=research&taxon_id=355146
