Diagnosis. Length of forewing is 7.5 mm in the male. This is the smallest species within the genus. Nephelomilta taprobana differs externally from other congeners by its small size, and the forewing ground color ochreous with a fuscous pattern. The male genitalia are similar to those of N. suffusa, but can be easily distinguished by the narrower distal section of costa with the ventral-apical process much narrower, claw-shaped and apically pointed, the significantly smaller ampulla, which does not reach the ventral margin of the valve, the weaker sclerotized plate of the carina, and the much smaller, spine-like cornuti on the distal diverticulum of the vesica.

Female is unknown.

Distribution. Endemic of Sri Lanka Island.
