Baeonoma leucodelta is a moth in the family Depressariidae. It was described by Edward Meyrick in 1914. It is found in Guyana[1] and Pará, Brazil.[2]
The wingspan is about 7 mm. The forewings are dark fuscous, with a slight purplish gloss and with a triangular white blotch extending on the dorsum from beyond the middle to near the tornus, and reaching half across the wing. There is a smaller white apical patch, its edge running from five-sixths of the costa to the termen above the middle. The hindwings are rather dark grey.[3]
