Stenoma collybista is a moth in the family Depressariidae. It was described by Edward Meyrick in 1915. It is found in Peru."Stenoma Zeller, 1839" at Markku Savela's Lepidoptera and Some Other Life Forms
The wingspan is 21–22 mm. The forewings are whitish-grey ochreous, sometimes partially suffused with pale violet grey and with the costal edge yellow whitish, at the base dark fuscous. There is a small triangular dark fuscous spot on the costa beyond one-fourth (sometimes obsolete), and larger ones in the middle and beyond three-fourths. The stigmata are small, indistinct and dark grey, the plical obliquely beyond the first discal. There is some faint brownish suffusion towards the middle of the dorsum, as well as a rather strongly curved row of indistinct grey dots crossing the wing from the third costal spot. A brownish terminal line is marked with a series of dark fuscous dots. The hindwings are grey.Exotic Microlepidoptera 1 (13): 384
