Monochroa discriminata is a moth of the Gelechiidae family. It was described by Meyrick in 1923. It is found in North America, where it has been recorded from southern Ontario. The wingspan is 12-13 mm. The forewings are grey. The stigmata are cloudy, blackish and often obscure, the plical obliquely before the first discal, sometimes a faint oblique shade of blackish irroration from near the costa at one-third to the first discal. There is an obscure whitish dot on the costa at two-thirds, preceded by slight darker suffusion, sometimes obsolete. The hindwings are grey.
