Stigmella singularia


The Stigmella singularia  group (designated here) (species 29)

Diagnostics ( Fig. 37View FIGURE 37): forewing varied: speckled or with one fascia. In male genitalia, phallus sometimes with small apical spines and always with many loose, large cornuti; valva with one apical processes which may be very pronounced; transtilla with or without small sublateral processes, only occasionally these processes are long; uncus with one or two caudal lobes; gnathos with two caudal processes which often are closely juxtaposed, occasionally merged into one lobe-like caudal process; vinculum small to large (occassionally very large), with small to large lateral lobes, often lateral lobes of vinculum are angular. Currently, the group comprises of about 16 species from the Andes of Ecuador and Peru: only five species are described here, 11 to be described later (Stonis et al. in prep.). Thus the species are trophically associated with at least three plant families ( Urticaceae  , Lamiaceae  , and Asteraceae  ) but Lamiaceae  feeders strongly predominate. Leaf-mines often combined, with abruptly widened, blotch-like distal parts, however, sometime they remain rather slender galleries throughout the course or gradually widening in distal part.
