( Figs 1, 3 , 32 , 37 )

Stigmella lobata Remeikis & Stonis, in Stonis et al. 2016d: 69 , 73–75, figs 204–212.

Material examined. 1 ♂ (holotype), PERU, Dept. Puno, 10 km N Lampa, Quabrada Metara , 15°17'44"S, 70°12'21"W, elevation about 3900 m, 31.iii–3.iv.1987, O. Karsholt, genitalia slide no. RA 553♂ ( ZMUC) ; 1 ♂ (paratype), 15 km E Ayaviri, Laguna Asnacocha , 14°49'44"S, 70°22'34"W, ca. 3940 m, 26–27.iii.1987, O. Karsholt, genitalia slide no. RA 559♂ ( ZMUC) .

Diagnosis. The combination of shining, copery golden forewing without fascia, large, apically angular inner lobe of valva, and specific set of four or three large spine-like cornuti in phallus distinguishes S. lobata from all other Stigmella species possessing one caudal process of gnathos in the male genitalia.

Male ( Fig. 32 ). Described in Stonis et al. 2016d: 69, figs 204, 205. Forewing length: 3.3–3.5 mm; wingspan: 7.1–7.6 mm.
