Stigmella marmorea Puplesis & Robinson, 2000: 26 –27, figs 18, 97, 98, 210.

Stigmella marmorea Puplesis & Robinson, in Stonis et al. 2016d : figs 123–127.

Material examined. 2 ♂ (holotype and paratype), 1 ♀ (paratype), PERU, Dept. Ancash, 23 km SE of Huaraz, Cerro Cahuish (Quabrada Pucavado), 4100 m, 15–18.ii.1987, O. Karsholt, genitalia slide no. Diškus 182 (holotype), Diškus 181 (paratype) ( ZMUC) .

Diagnosis. Belongs to the S. marmorea species group. The combination of two white to cream fasciae on the forewing and numerous large cornuti on the vesica distinguishes S. marmorea from all other Stigmella species.
