Pycnarmon argenticincta is a moth in the family Crambidae. It was described by George Hampson in 1899. It is found on New Guinea.[1]
The wingspan is about 22 mm. Adults are white, the forewings have an ochreous tinge and there are three basal black spots. There is an antemedial line arising from a black spot on the costa. Both wings have a prominent discocellular spot and a postmedial line from the costa to vein 5, then minutely dentate and at vein 2 retracted to below the angle of the cell. There is a marginal orange band with a black line on its inner edge, followed by a white line defined on the inner side with fuscous. There are also some marginal black specks.[2]
