Stenoma bryocosma is a moth of the family Depressariidae. It is found in French Guiana and Brazil.[1]
The wingspan is about 35 mm. The forewings are pale whitish fuscous, the costal edge whitish, suffused with greenish towards the base, as well as a green dot beneath the costa at one-fourth. There is a suffused yellow-greenish streak mixed irregularly with dark grey green from the base beneath the costa to beyond the middle, where it is enlarged into a costal spot, edged with blackish on the costa, then continued obliquely downwards to a dark spot in the disc beyond the cell. A similar streak is found from one-fourth of the dorsum converging to the same costal spot. The second discal stigma is dark green, transverse-linear, with anindistinct line of dark grey irroration running from this directly to the dorsum. There is a strongly curved row of grey-green dots from two-thirds of the costa to the dorsum before the tornus and there are three small black marks on the costa posteriorly. There is also a terminal series of grey dots. The hindwings are whitish grey.[2]
