Diagnosis. The species is well recognizable externally by the light forewing with well developed reddishbrown spots and the lack of greyish-black markings. The posterior margin of vinculum with broad anteromedial emargination and lateral humps in combination with a narrow, elongated gnathos (ration lenght/width = 6.6–7.0) and valva with strongly broadened apex are characteristic features in the male genitalia. The female genitalia are defined by the presence of two narrow folds on the subgenital plate in combination with a broad (ratio width/length = 1.8–2.0) segment VIII and broadly ovate (ratio length/width = 1.75–2.0) corpus bursae. The male genitalia are most similar to those of G. hoefneri (Rebel, 1909) but differ in the saccus being broader and the phallus with a longer distal portion. The gap between the sacculus and vincular process is broader and the sacculus is usually longer in G. rufomaculata . G. streliciella has a narrower vinculum and base of sacculus as well as a narrower saccus. G. cinctipunctella is similar to the new species in the shape of the sacculus, but the tegumen is narrower, the valva is longer, the gnathos is shorter and the hump of the posterior margin of the vinculum lies more laterally. The female genitalia most resemble those of G. hoefneri and G. cinctipunctella but are defined by very broad segment VIII and the presence of two distinct narrow folds on the subgenital plates.
Description. Adult ( Figs 21, 22 View FIGURES1–24 ). Wingspan 13.0–16.2 mm. Head white, neck mixed with brown in some specimens, labial palpus upcurved, white, segment 2 brown at base, outer surface slightly mottled with light brown, segment 3 with narrow black subapical ring; scape brown, other antennal segments brown with white basal rings; thorax and tegulae light brown; forewing ochreous, costal margin black from base to 3/4 length, veins mottled with black in apical 1/3, black dot in the middle width on 1/3 and in the middle length near dorsum, diffuse black pattern on the base of forewing near dorsum and on 2/3, basal half mixed with white, diffuse narrow angulated white fascia on 3/4, apex mottled with black, cilia white black-tipped; hindwing light grey.
Variation. The ochreous pattern may be divided into three large spots in cell, the extent of the black pattern along costal margin varies considerably.
Male genitalia ( Figs 46–48 View FIGURES 43–48 ). Uncus broad, apex triangular, pointed; gnathos weakly curved, narrow; tegumen moderately broad, anteromedial emargination deep, triangular; valva broad at base, curved in middle, apex inflated; sacculus broad at base, distal portion long, narrow, strongly downcurved, gap to vincular process broad; vinculum broad, posterior margin with broad medial emargination and with short hump-like lateral process; saccus subrectangular, top abruptly truncated, not extended beyond top of pedunculus; phallus narrow, pointed, with small subapical arm, caecum inflated, about 1.5 times shorter than phallus.
Female genitalia ( Figs 62, 63 View FIGURES58–63 ). Papillae anales elongate, subtriangular, densely covered with short setae; apophysis posteriores narrow, about twice length of segment VIII; segment VIII subrectangular, about 1.5 times broader than long, posterior margin with broad medial V-shaped emargination; subgenital plates connected medially and covered with microtrichia in medial portion; posteriolateral sclerites broad, triangular with rounded posterior corners, anterior corner strongly projected anteriorly, medial and lateral folds extended from medial and anterior corners of posteriolateral sclerites accordingly to anterior margin of segment VIII; anterior margin of sternite VIII strongly sclerotized, concave with paired medial projections; apophysis anteriores slightly shorter than segment VIII; colliculum as broader as long, ductus bursae narrow, inflated after colliculum; corpus bursae large, subovate, longer than ductus bursae, signum near entrance of corpus bursae, base subovate, distal portion broad, stout, weakly curved or as a long strongly curved in middle hook.
Variation. Signum hook varies from short, broad and weakly curved to moderately long, narrow and strongly curved in middle.
Biology. Host plant unknown. Adults were observed in steppe biotopes from June to August, up to 2330 m elevation.
Distribution. Russia: Zabaikalskiy krai; China: Ningxia and Inner Mongolia Autonomous Regions; South Korea.
Remarks. This species was recorded from South Korea as G. radkevichi ( Park & Ponomarenko 2006: 278, figs 12, 44; Park & Ponomarenko 2007: 70, Pl. 3, fig. 73; Pl. 76, fig. 73).
Etymology. The specific epithet is derived from the Latin rufus – red, and macula – spot, and refers to the large reddish-brown spots on the forewing.
