Brachmia dolosa is a moth in the Gelechiidae family. It was described by Meyrick in 1911. It is found in Sri Lanka. The wingspan is 10–12 mm. The forewings are whitish-ochreous, more or less sprinkled with brownish and dark fuscous. The stigmata is formed of blackish irroration, the plical rather obliquely before the first discal. There is a small transverse spot of blackish irroration on the dorsum somewhat before the second discal and an acutely angulated series of cloudy black dots close before the posterior third of the costa and termen. The hindwings are light grey.
