Description. Length of forewing 16.5–18.5 mm in both sexes. Head pale yellowish-brown scaled; vertex with roughly erected setose; frons pale yellowish-brown, rounded; maxillary palpus very short, brown; labial palpus exteriorly brownish, interiorly whitish, base of ventral side whitish, 3 rd segment small, brownish white scaled; proboscis basally brownish white scaled; antenna pale brown, long scape and short pedicel covered with brownish white scales, unipectinated every two segments and covered with pale yellow scales to dorsad, ciliated longer than half the length of diameter of antenna in male and shorter than half of the length of diameter of antenna in female to ventrad. Patagium and tegula pale yellowish brown, well-developed. Legs yellowish brown at dorsal, white at ventral. Ground color of both wings pale yellowish brown. Forewing with a dark brown spot near dorsum at base; antemedial line ochreish-brown, incurved, slightly concave below 1A+2A; orbicular spot small and dark brown; discocellular spot irregular kidney-shaped, dark brown; postmedial line ochreish-brown, from near end of vein R 2, somewhat outcurved, protruded and somewhat serrated between veins M 2 and CuA 2, curved to below of posterior angle of discodial cell, then bent and irregularly undulated to dorsum; costa well-developed, broad, ochreous banded; termen broad, yellowish-brown to ochreish-brown shade spaced apart from postmedial line. Hindwing with irregular ochreish brown discocellular spot; postmedial line ochreish-brown, protruded and serrated between veins M 2 and CuA 2, strongly curved to the base of hindwing near 3A; ochreish-brown scales indistinctly scattered between veins M 2 and CuA 2 near posterior angle of discodial cell; termen broad, yellowish-brown to ochreish-brown shade which was spaced apart from postmedial line. Both wings with fringe long, brown, basally dark brown. Abdomen covered with yellowish brown scales.

Male genitalia. Uncus short, trapezoidal, slightly concave at top. Anal tube as long as six times of uncus, subscapium sclerotized and basally curved to ventral. Tegumen broad, almost the same length of vinculum. Vinculum shorter than tegumen, U-shaped. Juxta rhomboidal, widen at anterior edge. Transtilla broad. Valva ovate, elongated, densely covered with setose, sparse hairs at dorsal of costa; fibula narrow, curved interiorly, apically scoop-shaped and pointed. Sacculus moderate, tapering to the end. Saccus pouch-shaped.Aedeagus cylindrical, moderate, slightly curved, coecum short; vesica granulated, two cornuti with a band consisting of minute serratures at a bulged area near base and a bunch of short spinulose at middle. 8 th tergite long, concave at anterior, narrow at posterior half, with two linear sclerotization on each side; 8 th sternite long, broad, weakly membranous at end of anterior and posterior (fig. 8b).

Female genitalia. Papilla anales covered with short setose.Apophyses anterior almost twice the length of apophyses posterior. Ostium conical, narrow at middle, a pair of ellipses folded, sclerotized and pointed. Ductus bursa narrow, wrinkled at posterior half, weakly sclerotized around single side of middle. An additional sac of corpus bursa with an irregularly widened cervix; signum large rhomboidal, pointed invagination at anterior end.

Diagnosis. This species is very similar to Patania harutai ( Inoue, 1955) , and hard to be distinguished from each other by adult characters. These species can be identified correctly by the male genital characters: P. gorosoe sp. nov. differs from P. harutai by having a concave uncus; subscapium six times the length of uncus; lateral arms of transtilla hardly angled; juxta rounded at the base; valva more densely covered with setose and smoothly rounded at distal; vesica with a band of cornuti narrow at bulged area, and a wavy bunch of spinulose thicker at middle in the male genitalia; signum longer than half the length of corpus bursa; an additional sac present at corpus bursa in the female genitalia. As for P. harutai , in the male genitalia the uncus is convex at the middle; subscapium is about three times the length of uncus; lateral arms of transtilla is broad and strongly angled; juxta is truncated at the base; valva is densely covered with setose after half and somewhat protruded at apical area; vesica with a band of cornuti broad at bulged area, and a straight bunch of spinulose finer at middle; in the female genitalia, signum is shorter than half the length of corpus bursa; corpus bursa is ovate.

Host plants. Acer palmatum Thunb., A. pictum Thunb. var. mono (Maxim.) Maxim. ex Franch (Aceraceae) .

Distribution. Korea (GW, GG, GB and JN).

Etymology. The species is named after the Korean name of the host plant Acer pictum Thunb. var. mono (Maxim.) Maxim. ex Franch , this “gorosoe”.

Remarks. Inoue (1982) noted the host plants of Patania harutai as Aesculus turbinata and in the genus Acer . In Korea, all of specimens of P. gorosoe sp. nov. emerged from two species of the genus Acer , and no P. harutai . Contrarily, all of reared specimens of P. harutai emerged from Styrax obassia Siebold & Zucc. in our study. Therefore, the information of host plants of P. harutai in Inoue (1982) needs reconsidering.
