Stigmella schoorli Puplesis & Robinson, 2000: 29 –30.

Stigmella schoorli Puplesis & Robinson ; in Stonis et al. 2016d: 46 , figs 18, 28, 118–122.

Material examined. 1 ♂ (holotype), PERU, Dept. Ancash, 35 km SE of Huaraz, Cerro Cahuish, Quabrada Pucavado , 9°40'19"S, 77°12'21"W, elevation 3870 m, 18.ii.1987, O. Karsholt, genitalia slide no. Diškus 200 ( ZMUC) ; 3 ♂, 5 ♀ (paratypes), label data as holotype, genitalia slide nos Diškus201, Diškus202, Diškus203, Diškus204, Diškus206 (ZMUC); 1 ♂ (not type series), same label data as holotype, genitalia slide no. RA554♂ (ZMUC).

Diagnosis. Belongs to the Stigmella schoorli group. The combination of an almost uniform forewing without a median fascia, pointed inner lobe of valva, and rather asymmetrical horn-like cornuti (rate: 1:1.4; the longer cornutus 1.6 times exceeds the width of phallus) distinguishes S. schoorli from S. epicosma , S. alticosma , and S. paracosma ). From similarly uniformly scaled S. hamata , S. schoorli may be easily distinguished by the distinctly bilobed uncus, one apical process of valva, long sublateral lobes of transtilla, and very large horn-like cornuti.

Male ( Fig. 32 ). Described in Puplesis & Robinson 2000: 29, 30, and Stonis et al. 2016d: 46, figs 118, 119. Wingspan: 5.8–6.0 mm.

Female. Similar to male.

Male genitalia. Illustrated in Stonis et al. 2016d: figs 121, 122.

Female genitalia. Illustrated in Puplesis & Robinson 2000: figs 213, 214.

Bionomics. Adults fly in February. Otherwise biology unknown.

Distribution ( Fig. 1 ). This species occurs in the high Peruvian Andes ( Peru: Ancash Departamento) at altitudes about 3870 m ( Fig. 5 ).
