Stachyostoma is a genus of moth in the family Gelechiidae. It contains the species Stachyostoma psilodoxa, which is found in Ecuador.[1]
The wingspan is about 23 mm. The forewings are pale ochreous, on the dorsal three-fifths brownish-tinged, and with scattered dark fuscous specks. There is a blackish dot towards the costa near the base. The discal stigmata are small and dark fuscous, the first with a similar dot obliquely before and above it connected by a fuscous cloud, and with a more conspicuous blackish dot obliquely above and beyond it. The hindwings are whitish-ochreous.[2]
