Rectiostoma argyrobasis is a moth in the family Depressariidae. It was described by W. Donald Duckworth in 1971. It is found in the humid low highlands of northern Venezuela and south-eastern Brazil.[1]

The wingspan is 14–16 mm. The forewings are white basally, tinged with yellow on the costal edge. The distal margin of the white area is bordered by a dark brown line immediately paralleled by a broad, transverse band of iridescent blue violet. The apical half of the forewing is dark brown suffused with iridescent bronze-to-violet scales. The hindwings are dark brown with a white patch on the anterior margin and white hair-pencils along the anal veins.[2]
