Diagnosis.
Belongs to the
Stigmella schoorli
group. The combination of a golden shining base of forewing and unequally developed horn-like cornuti (rate: 1:1.9; the longer cornutus 1.5 times exceeds the width of phallus) distinguishes
S. alticosma
from the most resembling members of the group (
S. epicosma
and
S. paracosma
sp. nov.
). From similar
S. schoorli
and
S. hamata
,
S. alticosma
may be easily distinguished by the shiny median fascia of forewing and rounded inner lobe of valva.
Forewing dark brown with golden gloss and purple iridescence, with two silvery shining fasciae (median and apical) and (concolorous with thorax). The combination of: forewing possesing two silvery shining fasciae and shiny golden base, deeply divided uncus, specific set of two large but unequal horn-like cornuti in male genitalia (with cornuti ratio 1:2) distinguishes
S. alticosma
sp. nov.
from all other
Stigmella
species.
