Ditrigona furvicosta is a moth in the family Drepanidae. It was described by George Hampson in 1911. It is found in India (Sikkim, Darjeeling), western China and probably Tibet. The wingspan is 12.5-15.5 mm for males and 15.5 mm for females. The forewings are white with a conspicuous buff costa. There are five brownish-grey, weakly lunulate transverse fasciae, consisting of indistinct sub-basal, antemedial, postmedial and two subterminal fasciae with the greatest distance between antemedial and postmedial fasciae. The hindwings are similar to the forewings in colour and pattern.
