Figs 9 View FIGURES1–24 , 55 View FIGURES 52–57

Type material. Holotype ♀, CHINA: Liuyangbu (37°53' N, 107°23' E), Yanchi County, Ningxia Hui Autonomous Region, 11.vi. 2014, 1320 m (Houhun Li, Wei Guan & Meiqing Yang) (gen. slide no. L13071) ( NKU).

Diagnosis. Externally the species can be easily recognized by the uniformly yellow head and forewing. The narrow hockey-stick-shaped posteriolateral sclerites in combination with a long, narrow ductus bursae (ratio length/width = 4) are characteristic for the female genitalia.

Description. Adult ( Fig. 9 View FIGURES1–24 ). Wingspan 14.5 mm. Head dirty white to light grey, labial palpus light yellow, scape yellow, other antennal segments yellow with narrow grey rings; thorax, tegulae and forewing plain yellow, cilia white; hindwing and cilia grey.

Male genitalia. Unknown.

Female genitalia ( Fig. 55 View FIGURES 52–57 ). Papillae anales elongated, subtriangular, densely covered with short setae; apophysis posteriores narrow, more than two times longer than segment VIII; segment VIII subrectangular, longer than broad; subgenital plates separated with narrow membranous area, evenly sclerotized, posteriolateral sclerites hockey-stick shaped, weakly broadened posteriorely; anterior margin of sternite VIII strongly sclerotized, concave, with paired medial projections; apophysis anteriores two times shorter than segment VIII; colliculum elongated with lateral sclerotization; ductus bursae long and narrow; corpus bursae slightly longer than ductus bursae, elongated, signum near entrance of corpus bursae, basal plate small, distal portion long, narrow, straight to 2/3 length then strongly curved, apex pointed.

Biology. Host plant unknown. The holotype was collected in the first half of June at an elevation of 1320 m.

Distribution. China (Ningxia).

Remarks. The female genitalia remotely resemble those of G. nordlandicolella and G. fuscescens sp. nov., but the total length of the genitalia is greater (about 4.5 mm rather than 3.3 mm in the related species), sternite VIII is more elongated, the posteriolateral sclerites differently shaped and the signum is more slender and stronger curved.

Etymology. The specific epithet is derived from the Latin gilveus, meaning yellow, and refers to the dominant colour of the forewing.
