Polyhymno oxystola

Polyhymno oxystola is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1913. It is found in Mpumalanga, South Africa.[1][2]

The wingspan is 11–12 mm. The forewings are rather dark fuscous, the dorsal area lighter. There is a rather broad shining white median longitudinal streak from the base to near the termen, posteriorly acutely pointed, edged beneath by a streak of dark fuscous suffusion. There is a white line along the costa from near the base to near the middle, then running obliquely into the apex of the median streak. A suffused white streak is found beneath the submedian dark fuscous streak from before the middle of the wing to its extremity, sending a suffused oblique branch to the tornus. There is a silvery-metallic acutely angulated transverse line beyond the apex of the median streak, becoming white towards the costa, the lower portion almost terminal. A pale brownish-ochreous slender streak runs above the angle of this from near the costa into the apex and there are two oblique white wedge-shaped marks running from the costa into this, the second followed by a blackish dot very finely edged posteriorly with whitish. The hindwings are grey.[3]
