Brachmia anisopa is a moth in the Gelechiidae family. It was described by Meyrick in 1918. It is found in Colombia. The wingspan is about 15 mm. The forewings are dark purplish-grey with two ochreous-brown discal spots finely edged blackish, representing the stigmata, the first before the middle, larger, transverse-oval, connected with the dorsum by a subquadrate spot of blackish suffusion edged laterally with whitish, the second at three-fifths, round, partially edged finely whitish. There is a small whitish spot on the costa at four-fifths, with indications of a transverse series of minute whitish dots beneath it. There is also a marginal series of minute blackish dots around the apex and termen, edged anteriorly by minute white dots. The hindwings are grey.
