Figs. 6–7 View FIGURES 2 – 9 .

Description. Body: Antennae filiform in both sexes, male with short cilia, length of each segment in the middle longer than width. Frons flat, white, with a cluster of developed forelock under the frons. Labial palpus white-yellow, rough scaled, about 1 / 4 – 1 / 3 length extending beyond frons. Dorsum of thorax and abdomen, and upper half of lateral side of the latter dark grey mixed with white. Venter of thorax and abdomen, lower half of lateral side of abdomen whitish. Hind tibia with two pairs of spurs, the length of inner ones about two times the outer ones in each pair. Male with a pair of well developed coremata between the seventh and eighth sternite.

Wings: Length of forewing: ɗ 13–15 mm, Ψ 15–16 mm. Wings grey to yellowish-grey, intermixed with little cyan, with several white wavy transverse lines. Forewing: subbasal, antemedial and medial lines shallowly arced, slightly wavy; middle area with two white lines, the proximal one broad and often forming a narrow band, generally indistinct, the distal one wavy, quite narrow and weak; postmedial line distinct, serrate, protruding outward between M 3 and CuA 1; submarginal line dentate; terminal line dark grayish brown. Hind wing: lines (from the proximal line of the middle area to submarginal line) continuous with that of forewing. Fringes concolorous with wings. Underside: dull brown; subbasal, antemedial and medial lines of forewing absent, other lines same as that of upperside; discal spot visible on forewing, indistinct.

Male genitalia ( Figs. 14 View FIGURES 10 – 15 , 20 View FIGURES 16 – 21 , 24). Uncus long and stout, coniform, well sclerotized, ciliate. Valva short and narrow, costal lobe quite narrow, less than one half of sacculus in width in the middle, much longer than sacculus, posterior end blunt, ventral setae much denser on both ends, the long setae at the posterior end of costal lobe straight and pointed outwards; sacculus quite short, posterior end blunt, ventral margin protruding near base, incurved in the middle. Saccus triangular but blunt. Juxta, aedeagus as in redescription of the genus.

Female genitalia ( Fig. 28 View FIGURES 26 – 29 ). As in redescription of the genus.

Diagnosis. The wing pattern of G. magaria   is close to that of G. unduliferaria   . The new species is characterized by its male genitalia: the costal lobe of the valva is longer and narrower than the sacculus, whereas in G. unduliferaria   the costal lobe is only slightly longer and narrower than the sacculus; long setae at the posterior end of costal lobe are straight and pointed outwards in G. m a g a r i a, not curved and pointed inwards as in G. unduliferaria   ; the ventral margin of the sacculus in G. magaria   is more protuberant than in G. unduliferaria   .
