Material examined. 14 ♂ (lectotype and paralectotypes), 6 ♀ (paralectotypes), PERU, La Oroya, 3720 m, vii.1914, Parish, genitalia slide nos 20612 BMNH (lectotype), 28841 BMNH (paralectotype) (BMNH).

Diagnosis. Belongs to the S. marmorea species group. The pale, ochreous cream or yellowish cream, male forewing (in females with purple-brown apical apex), wide, rather square valva with small, curved apical process together with 10 very large horn-like cornuti in the male genitalia distinguish this species from all other Stigmella species.
