Stigmella kristenseni Diškus & Stonis, in Stonis et al. 2016d: 69 , figs 191–203.

Material examined. 1 ♂ (holotype), PERU, Dept. Lima, 45 km NE Chosica, Millo Valley, Quabrada Yanac , 11°36'30"S, 76°24'18"W, elevation ca. 4000 m, 26–28.i.1987, O. Karsholt, genitalia slide no. AD 670♂ ( ZMUC) ; 1 ♂, Dept. Ayacucho, 25 W Puquio, Senal Cerro Palmaderas , 14°39'41"S, 74°27'31"W, elevation ca. 4100 m, 10– 12.iii.1987, O. Karsholt, genitalia slide no. AD 654♂ ( ZMUC) .
