Records from Northern Territory (Groot Eylandt), New South Wales and Victoria in Australia are interpreted as vagrant or mislabelled specimens.
There are four "grey" Psilogramma specimens in NHMUK from Seram and Buru. The two males from Seram are very close matches in habitus for Psilogramma papuensis from New Guinea; the identies of the two females from Buru are more equivocal. So far, no "grey" Psilogramma have been reported from the Southern Moluccas and although these four moths are provisionally identified here as Psilogramma papuensis, they should be studied in more detail, ideally with DNA barcoding.
Eitschberger (2001: 106) (STI 17722) illustrated the genitalia of a male identified as a "paratype" of Psilogramma mastrigti (though it was not listed as such in the original description; Eitchberger, 2001: 7; STI 17720) from Sulawesi but made no further mention of the specimen. Given that it is highly unlikely Psilogramma papuensis occurs on Sulawesi (no other specimens have ever been recorded from that island despite intensive collecting), the record is here considered to be an error and not mapped, but whether this is a misidentification or mislabelling is presently unknown.
