( Figs 1 , 34 , 37 )

Stigmella evanida Diškus & Stonis, in Stonis et al. 2016d: 58 , 59, 61, figs 18, 27, 157–161.

Material examined. 1 ♂ (holotype), PERU, Dept. Lima, 10 km N Oyón, Quabrada Quichas, Pueblo Quichas , 10°34'17"S, 76°46'03"W, 4000 m, 24–26.ii.1987, leg. O. Karsholt, genitalia slide no. AD 672♂ ( ZMUC) .

Diagnosis. Belongs to the S. expressa group. The combination of very long and slender, closely juxtaposed processes of gnathos, long thickened uncus, very short vinculum, transtilla without sublateral processes, and small spine-like cornuti distinguishes S. evanida from all other Stigmella species, including the members of S. expressa group.
