Idiophantis carpotoma is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1916. It is found in southern India.[1]
The wingspan is about 14 mm. The forewings are dark fuscous, with the bases of the scales pale greyish ochreous and two yellow semi-oval dorsal blotches reaching halfway across the wing, the first about one-third, the second on the tornal area. There is a fulvous-yellow line from three-fifths of the costa to the posterior extremity of the second blotch, right angled in the disc, edged with black posteriorly towards the extremities, followed by a leaden streak from the costa, black edged posteriorly towards the costa, expanded beneath into a coppery-tinged spot filling the tornal prominence and marked with a black dot at its apex. The apical prominence beyond this is ferruginous yellow, cut by a short oblique white line near its base, continued along the lower margin to the apex. The hindwings are light grey.[2]
