I am interested that you think this is P. sparsa rather than P. diemeni. What criteria are you using to distinguish these species?

Moths of Victoria, Part 8, on their supporting disc, give quite detailed notes on separating the Pantydia spp, they recognize; especially separating P. sparsa from P. diemeni. I quote (at page 2/5 for P. diemeni): 'While most Pantydia can be separated by examining the underside of the hindwing, most live P. diemeni can be recognized by the break in the transverse line (A).' This line is pointed to by an arrow in the supporting illustration. It is the fine white/yellow line running parallel to the trailing edge of forewing in Pantydia species. In Sighting No, 4416300 that line is entire and not broken ie. P, sparsa. In Sighting No, 4416299 that line is not entire and is broken, hence P. diemeni.

On these criteria, the photo on BFH labelled 18/03/2005 appears to be P. sparsa not P diemeni and I think should be reviewed (and maybe replaced).

I rather presumed BOLD had checked the DNA of the specimen in that photo, before putting it in http://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=70301. Can one tell from the 'bins' if that specimen is anomalous?

I do not know how to interpret the 'BINs' data.

The specimens in
http://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=19181
and
https://www.boldsystems.org/index.php/TaxBrowser_TaxonPage?taxid=70301
both have variable but similar forewing submarginal lines.
How good is your French, see
https://www.biodiversitylibrary.org/item/105800#page/447/mode/1up
where Guenée describes both species.
What does he imply is the main difference?

I'm afraid my French is not up to it. But having seen the as yet unpublished draft of 'Moths of the ACT', know the distinction I described will be borne out by the comparitive photos of the two species - although the text does not describe the difference in words.
