Male ( Fig. 7 ). Body elongate oval. Female ( Fig. 8 ). Coloration and vestiture as in males, but body form more ovoid.

Coloration. General coloration pale yellow and weakly greenish, dorsum without any dark marking, covered with golden, shining setae; antenna yellow, segment IV often weakly darkened; eyes blackish brown; labium infuscate at apex; membrane pale, hyaline, without dark spots; legs yellow, tibial spines yellow without spots at bases; abdomen greenish, genital capsule yellow.

Structure. Dorsum shining and smooth; clypeus at most barely visible from above; frons and vertex slightly convex; eyes granular, occupying nearly total side of head in lateral view, eye width smaller than interocular distance; antennal segment II longer than width of head, segments III and IV more slender than segment II, total length of segments III and IV longer than segment II; labium reaching mesocoxa; pronotum evenly convex, calli not demarcated, posterior margin weakly concave across moderately exposed mesoscutum; scutellum very weakly convex; hemelytra weakly deflexed at fracture, always macropterous, apex of abdomen reaching about posterior margin of membrane cells, corial margin very weakly convex in males, distinctly convex in females; genital capsule large in males, occupying about half of length of abdomen.

Male genitalia ( Figs 9–12 ). Vesica sigmoid with two apical spines, anterior apical spine acuate, longer than posterior, posterior apical spine hooked with a tooth near the apex, secondary gonopore subapical, developed, with one sclerotized stick below it; left paramere boat-shaped; right paramere lanceolate; phallotheca with a project near apex.

Host plant. Nitraria spp.

Etymology. The name of this species refers to its host plant Nitraria spp.

Remarks. The species is most confused with G. gobicum on the basis of size and coloration, but easily separated by the structure of the male genitalia. It is also similar to G. muminovi in the shape of vesica (the posterior apical spine with a tooth near apex), but the latter has general coloration blackish brown, much darker than G. nitrarium sp. nov., and right paramere relatively truncate apically.
