Thubana bullulata is a moth in the Lecithoceridae family. It was described by Meyrick in 1923. It is found in India (Assam). The wingspan is about 17 mm. The forewings are ochreous-whitish, suffused with pale brownish except for a triangular blotch on the middle of the costa reaching half across the wing, and an undefined transverse patch before the termen. There is a small costal mark of dark fuscous suffusion on each side of the costal blotch, and a transverse-crescentic dark fuscous mark adjoining its apex posteriorly. A bar of fuscous suffusion is found near the base, with some fuscous irroration in the disc and towards the dorsum before the middle, as well as a cloudy streak of fuscous suffusion along the termen. The hindwings are rather dark fuscous, lighter and ochreous-tinged towar
