Could this be E. niphobola which is very similar to E. marginalis but BOLD (Hobern) gives a more appropriate distribution for? Otherwise this is a much more northerly record compared to Bold or iNat records.
@WendyEM You are probably correct, I have looked at the barcodes, marginalis is in 5 bins and looks like it only reaches into southern QLD and probably not the real marginalis. E. niphobola on the other hand has its type from Townsville. It fits into 4 Bins one of which (from NSW) coincides with one of the marginalis bins; a second bin has 2 specimens from South Australia; a third bin with 2 specimens one from S.E.QLD the other from Victoria and the fourth bin with 8 specimens are all from Townsville, from the one area by the late Graeme Cocks (these may be the true niphobola based on type location). So mine may well be niphobola based on its location. BOLD also has a E, niphobola PS1 in a bin of its own from the NT and a E. niphobola PS2 in a bin of its own from S.E.QLD
