Diagnosis. G. discussa has narrower and more rounded forewings comparing with that of G. decussa , with generally more obsolescent markings. The maculation of the new species is less conspicuous, with less sharply defined ochreous outlines of the reniform and orbicular stigmata; the claviform stigma is narrower, more obsolescent. The dark intermacular patch of the cell, the basal dash and the subterminal arrowheads are also less sharply marked; the darker suffusion of the hindwing is more diffuse.

Comparing the male genitalia of the two sister species, the uncus of G. discussa is slightly broader than in G. decussa , slightly spatulate terminally; the valvae have a less convex dorsal costa; the harpe is slightly more elongate; the dentate, ribbon-like extension of the carina is only slightly arcuate, recurved terminally; the bulbed cornutus is more acute and about twice as large as in G. decussa .

The female genitalia of G. discussa differ from those of G. decussa and G. shchetkini by their characteristic, long and deep, sometimes sinuously folded ventral crest of the anterior third of ductus bursae, terminated in a large, more or less globular ventral pouch, both related species have a deeper or shallower arch at anterior edge of ventral plate instead of this structure (see Figs 24–29 View Figs 24–29 ). The ostium bursae is smaller than that of G. decussa but larger than in G. shchetkini , the medio-caudal incision is the smallest in G. discussa . The anterior third of the ductus bursae is less dilated, its lateral margins are almost parallel, this part is broader ( G. decussa )or conspicuously broader ( G. shchetkini )in the two related species.

Description. Wingspan 30–35 mm, length of forewing 13–15 mm. The main external features fit well with those of the decussa -group, the differential characteristics are given in the diagnosis. The holotype (male)and a typical female are illustrated in Figs 53 and 54 View Figs 50–57 .

Male genitalia ( Fig. 4 View Fig ): Uncus slightly broader, slightly spatulate terminally; dorsal costa of valva only slightly convex; harpe small, more elongate; pollex long and curved; juxta shield-shaped with narrow and shallow incision apically; aedeagus straight, long and strong; dentate ribbon slightly arcuate, recurved terminally; bulbed cornutus large, acute.

Female genitalia ( Figs 26, 27 View Figs 24–29 ): Ovipositor medium-long, rather weak; gonapophyses slender, fine. Ostium bursae sclerotized, its ventral plate relatively short, broadly triangular, caudal edge almost straight, with minute medio-caudal incision only. Ductus bursae strongly, granulously sclerotized, more or less flattened, long, broad, with almost parallel lateral margins, only posterior third dilated slightly. Ventral surface of ductus bursae with fine longitudinal medio-lateral suture, anterior third with long and deep, sometimes sinuously folded large crest running into a rather globular, big ventral pouch. Apical part of bursa copulatrix small, flattened-conical, wrinkled, partly gelatinous and scobinate. Appendix bursae rather long, elliptical, finely wrinkled and gelatinous; corpus bursae elliptical-saccate; signa absent.

Bionomics and distribution. G. discussa is distributed from the Zeravshan and Hissar Mts through the western Pamir Mts to NE Afghanistan (Prov. Badakhshan), mostly at medium but exceptionally also at rather high elevations.

Etymology. The specific name refers to the less sharply defined markings of the new species.
