This looks like quite a worn specimen so that the distinguishing species that Moths of Victoria uses to distinguish the Dysbatus (Line moth) species are somewhat indistinct, see MoV supporting CD to Part 5, see the 'Separating Dysbatus species' page . However, I think D. stenodesma can be ruled out because the black curved line extending from the forewing wing tip only extends about half way to the outer transverse first line of the forewing. In D. stenodesma MoV says this line extends 'almost to' the outer transverse line. I also think D. singularis can be ruled out because the outer transverse line curves are shallow and it has a simple point in that species. Whereas in this specimen (although faint) I think the outer transverse line curves are stronger and it has a flattened point. I think these characteristics suggest this specimen is more consistent with 'Dysbatus sp.(1)' as defined by MoV or simply Dysbatus sp,(genus), for our purposes.

I agree with all of this Ian, thanks for the analysis.
