OK, interesting. The apparent kink at inner edge of the hindwing is very pronounced here. We have usually relied on the pronounced upward kink of the main dark line of the hindwing at the outer edge (not visible here) for a definitive ID of E. ecursaria. I see the MoV notes seem to acknowledge many E, excursaira specimens don't show the downward kink of the holotype and are regarded as 'variants' of the species. On Bold(Hobern) there seem to be only a few of those shown with the downward kink clearly visible,

The ANIC holotype on p. 3/7 of MoV Part 7 CD has quite a good kink. Mine is exagerated by the angle of the shot and because it is hanging on a pine needle not sitting on a sheet or pinned flat.

I have never seen an E. excusaria specimen with such a sharp downturned kink in the hindwing main dark line. However E.mniara shows this feature, see here:-

I checked Moths of Victoria CD tonight. File Ectropis shows antennae for the different species. E. excursaria has short pectenations like above.
