Stigmella andina ( Meyrick, 1915) , in Puplesis & Robinson 2000: 24, figs 14, 88, 89, 209. Stigmella andina ( Meyrick, 1915) , in Stonis et al. 2016d: 67, 68, figs 186–190.

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.

Male ( Fig. 32 ). Re-described in Puplesis & Robinson 2000: 24, fig. 14, and and Stonis et al. 2016d: 67. Forewing length: 2.4–2.7 mm; wingspan: 5.2–5.9 mm.

Female ( Fig. 35 ). Re-described in Puplesis & Robinson 2000: 24, fig. 14, and and Stonis et al. 2016d: 67.

Male genitalia. Illustrated in Puplesis & Robinson 2000: figs 88, 89 and Stonis et al. 2016d: 188–190.

Female genitalia. Illustrated in Puplesis & Robinson 2000: fig. 209.

Bionomics. Adults fly in July. Otherwise biology unknown.

Distribution ( Fig. 1 ). This species occurs on the Altiplano in the Peruvian Andes ( Peru: Yauli Departamento) at altitudes about 3720 m.
