Stigmella expressa


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

Diagnostics ( Fig. 37View FIGURE 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  .
