Type locality: T ongzhong Forest Farm, Shangsi County, Shiwandashan National NR, Fangchenggang City, Guangxi Zhuang Autonomous Region, China.

Diagnosis. This species can be distinguished easily from G. situla  based on the following characters: wings pale gray with dark gray bands; dorsum of abdomen gray without black patches; apex of the abdomen covered with gray hairs; uncus bifid; gnathos slim; saccus swollen apically.

Description. Male: wingspan 32–38 mm; forewing length 16–18 mm;, body length 12–15 mm.

Head. Vertex densely covered with white scales; compound eyes large and elliptical dense black scales around them; labial palpus yellow, elongated downwards; antenna bipectinate, about 1 / 3 length of forewing, dark brown dorsally, basal 1 / 4 white.

Thorax. Dorsum yellowish-brown, covered with dense yellow scales. Fore- and hindwings grayish-white, covered with dense white scales; antemedial line broad and gray, from CuA 2 to inner margin; discal cell with a reniform stigma and a small gray dot; postmedial line broad and curved from M 1 curved to inner margin, represented by black scaling on the veins from M 1 to the costa; terminal line broader and gray, along the outer margin. Postmedial and terminal lines of hindwing not incomplete, unclear; discal cell with a gray spot; inner margin with 3 black spots. Postmedial and terminal lines on forewing underside broad and gray; discal cell with a small dot. Fore- and midlegs black, hindleg orange; tibia covered in brown scales.

Abdomen. Dorsum gray, without black patches, apex covered with gray long scales.

Male genitalia. Uncus bifurcate, each branch with a dorsal, sharply pointed process; valvae fused basally, deeply bifid to near the base, costa long and sickle-shaped; sacculus apically blunt, with sparse long scales, clearly thinner than costa; saccus well-developed, swollen distally, about 2 / 5 length of the whole male genitalia; aedeagus slender and long, smooth, the middle thinner than either end; coecum penis with a bifurcate apical process. Tergite VIII goblet-shaped, anterior margin with two long, very thin, laterally directed bars. Sternite VIII broad, posterior margin medially invaginated, V-shaped, apically with two pairs of processes, the outer broad and apically blunt, the inner longer, curved and sharply pointed; anterior margin with two long processes, apically curved outward and expanded.

Female. Unknown.
