Psilogramma lifuense
Diagnostic description:
A paler species, some specimens nearly all white on the thorax and forewing. Forewing upperside with the black discal streaks between veins M3 and CuA2 thin, often partly or totally obsolete; no distinct medio-costal brown area even in dark specimens; in dark specimens the discal lines are pronounced; in pale ones the markings, including the proximal part of the apical black line, become indistinct.
Distribution:
Records from Vanuatu are implied by DNA barcode data but it is unclear whether these are errors or whether the species actually occurs there.
