Idiophantis soreuta is a moth of the Gelechiidae family. It was described by Meyrick in 1906. It is found in Sri Lanka.
The wingspan is 13-14 mm. The forewings are pale brownish-ochreous, towards the apex yellowish-tinged and with a dark fuscous patch extending along the costa from the base to two-thirds, not reaching half across the wing, the lower edge with two short darker rounded prominences before the middle, the posterior edge straight, oblique. There are a few variable scattered dark fuscous dots or dashes between this and the dorsum, as well as a fine whitish fuscous-edged line from three-fourths of the costa to the dorsum before the tornus, right-angled above the middle with the arms subsinuate. A whitish streak is found along the costa towards the apex, edged with fuscous beneath. There is also a small dark metallic-bronze spot on the termen beneath the middle. The hindwings are fuscous.
