Lethata pyrenodes is a moth of the family Depressariidae.

The forewings are deep pinkish-yellow-ochreous with a fuscous triangular spot on the middle of the costa.

There is a faint shade of fuscous suffusion from the costal spot passing behind this to the dorsum and a faintly indicated somewhat darker rather curved line from three-fourths of the costa to near the tornus.

The hindwings are ochreous-whitish, towards the apex and termen faintly yellowish-tinged.
