Helcystogramma cerinura is a moth in the Gelechiidae family. It was described by Meyrick in 1923. It is found in Brazil (Para). The wingspan is 12-13 mm. The forewings are rather dark fuscous with the plical and first discal stigmata represented by a rather 8-shaped brownish spot edged with some blackish scales. There is a short fine whitish line from the dorsum preceding this, and the second discal forms a roundish similar spot. There is also a small cloudy whitish spot on the costa at five-sixths, as well as some marginal white specks around the apex and termen. The hindwings are grey.
