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 : 21

The Stigmella expressa group (designated here) (species 6 to 11)

Diagnostics ( Fig. 37 ): forewing speckled to almost unicolorous pale (but not very glossy or shiny). In male genitalia, phallus with two horn-like cornuti; valva with two apical processes; uncus with three to four caudal papillae (not with two well-separated caudal lobes); gnathos with two closely juxtaposed caudal processes and usually with a laterally extended plate; vinculum usually with a large ventral plate and lateral lobes. Currently the group comprises of seven similar but still differing Andean species: one from Ecuador ( Stigmella lachemillae Diškus & Stonis ) and six from Peru. Host-plant relationships: at least one species ( S. lachemillae ) feeds on Lachemilla Rydb. , Rosaceae , while larvae of S. acalyphae sp. nov. and S. lepida sp. nov. feed on Acalypha L., Euphorbiaceae .
