Stonis, Jonas R., Diškus, Arūnas, Remeikis, Andrius, Karsholt, Ole & Torres, Nixon Cumbicus, 2017, Illustrated review of the leaf-mining Nepticulidae of the central Andes (Peru and Bolivia), Zootaxa 4257 (1), pp. 1-70 : 34

The Stigmella marmorea group (designated here) (species 22–28)

Diagnostics ( Fig. 37 ): forewing varied: speckled or with one–two fasciae, occasionally glossy, without fascia; at least one species is known with distinctive androconia on abdomen. In male genitalia, phallus sometimes with very small to large apical spines and always with many loose large, mostly horn-like, cornuti; valva with two apical processes; transtilla with or without very small sublateral processes; uncus often with four caudal papillae, sometimes bilobed; gnathos with two caudal processes; vinculum large (occassionally very large), with small to large lateral lobes. Currently the group comprises of about 29 species from the Andes of Colombia, Ecuador, Peru, Bolivia, Chile and Argentina: twenty-two of the species are described, remaining undescribed (Stonis et al. in prep.). Trophically species are associated with at least five plant families: Euphorbiaceae , Rosaceae , Urticaceae , Lamiaceae , and Asteraceae . Leaf-mines as rather slender galleries, occasionally with distal parts resembling blotches.
