Stigmella magnispinella


The Stigmella magnispinella  group (designated in Stonis et al. 2016f) (species 36, 37)

Diagnostics ( Fig. 37View FIGURE 37): externally, the species are characterized by a rather dark frontal tuft varying from ferruginous brown to dark brown (not orange as in the most of other Stigmella  species); collar often darkened, varying from whitish grey to brown (rarely cream); forewing with a golden gloss and with a slender or ill-defined, silvery shiny postmedian fascia (absent in S. magnispinella Remeikis & Stonis  ); some silvery shiny or cream scales form apical fascia or apical spot. In male genitalia, phallus with a specific set comprised of one large, faceted, hornlike cornutus and a group of small spine-like and (or) plate-like cornuti; uncus deeply divided into two lateral lobes; valva with two apical processes (reduced in S. varispinella Diškus & Stonis  ) and a specific basal connection (except S. patagonica Remeikis & Stonis  ); transtilla with large sublateral processes (except S. patagonica  ); phallus usually truncated and weakly sclerotized basally. Currently the complex comprises five species: all occurring in the Andes (one in Ecuador, two in Peru, and two in Argentina). Trophic relationships: specimens of S. patagonica  has been collected around Discaria serratifolia  , Rhamnaceae  , while two other species were recorded as a leaf-miners of Asteraceae  .
