Helcystogramma cerinura is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1923. It is found in Pará, Brazil.[1]
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.[2]
