Stigmella olyritis ( Meyrick, 1915) in Puplesis & Robinson 2000: 31 , figs 28, 131, 132, 215.

Material examined. 3 ♂ (lectotype and paralectotypes), 3 ♀ (paralectotypes), PERU, Lima, 150 m, viii.1914, Parish, genitalia slide nos 28851 BMNH (lectotype), 28852 BMNH (paralectotype) ( BMNH) .

Diagnosis. Belongs to the S. nivea species group. The combination of closely juxtaposed processes of gnathos, two apical processes of valva, distally rounded uncus, long vinculum, and a band of numerous spine-like cornuti distinguishes S. olyritis from all other members of the group.

Male. ( Fig. 35 ). Described in Puplesis & Robinson 2000: 31, figs 28. Forewing length: 1.7–1.9 mm; wingspan 3.8–4.2 mm.

Female. Externally similar to male.

Male genitalia. Illustrated in Puplesis & Robinson 2000: figs 131, 132.

Male genitalia. Illustrated in Puplesis & Robinson 2000: figs 215.

Bionomics. Adults fly in August. Otherwise biology unknown.

Distribution ( Fig. 9 ). This species occurs in Peru (Lima) at altitudes about 150 m.
