Hapalonoma argyracta is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1914. It is found in Guyana.[1]
The wingspan is 9–10 mm. The forewings are white or ochreous whitish, with some scattered dark fuscous scales and with a blackish streak along the basal third of the costa and elongate blackish costal marks beyond the middle and at three-fourths, the latter edged beneath with ferruginous. There is a dark fuscous dot above middle of the disc, sometimes with some dark suffusion around it. Some variable dark fuscous suffusion or irroration is found towards the dorsum and there is a silvery-metallic subdentate submarginal line around the posterior part of the costa and termen, preceded by an angulated whitish line and then by a band of light brownish suffusion, with an interrupted black dash on the angle of the line, the costa and apex beyond this ferruginous. The hindwings are dark grey.[2]
