Pyncostola illuminata is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1913. It is found in South Africa, where it has been recorded from Mpumalanga, KwaZulu-Natal, Gauteng and Limpopo.[1] [2]
The wingspan is 18–21 mm. The forewings are light brownish ochreous, all veins marked with pale greyish-ochreous streaks irrorated (sprinkled) with dark fuscous. There are dark fuscous dots between these streaks beneath the costa at one-fifth and one-third, one on the fold between these, and three representing the stigmata, the plical very obliquely before the first discal. The hindwings are pale ochreous grey.[3]
