Redescription. Adult ( Fig. 13 View FIGURES 11 – 14 ) with wingspan 17.0¯18.0 mm. Head dark brown; vertex blackish brown; occiput silvery gray. Labial palpus with first segment grayish white; second segment grayish white basally, darkening to grayish brown distally; third segment purplish black. Antenna blackish brown, with bluish violet metallic luster, basal 5/6 of flagellum with dense pectinate scaling on dorsal edge. Patagium blackish brown tinged with ferrugineous red. Thorax blackish brown, medially with a longitudinal orange red band; metathorax grayish white. Tegula ferrugineous red, with scattered pale brown scales in posterior half. Forewing ferrugineous red, costal margin blackish brown along basal 1/3; black streaks extending along veins; dorsum with a black spot at base; cilia dark brown tinged with ferrugineous red. Hindwing ferrugineous red in basal half, yellowish white on anterior area under forewing, brown in distal half; dorsum with semi-elliptical hyaline space at base; cilia grayish brown. Legs blackish brown. Abdomen black on dorsal surface except first and third tergites white posteriorly; grayish white on ventral margin.

Male genitalia ( Fig. 19 View FIGURES 15 – 20 ). Uncus broad at base, narrowed to 3/5, then widened to apex, with densely spaced long hairs laterally; apex waved, with a small notch at middle, with two tooth-like posterolateral processes. Ganthos reduced. Tegumen trapezoidal, about twice length of uncus. Valva narrow at base, gradually broadened towards blunt apex, with densely spaced long hairs in distal half; costa slightly concave medially; transtilla elongate bar shaped, slightly arched inward; sacculus reaching ventro-apex of valva, basal 1/3 broad, distal 2/3 gradually narrowed. Vinculum narrow; saccus trapezoidal, about 1/3 length of uncus. Juxta small and rounded; anellus lobes long clubbed, with dense long setae. Aedeagus about same length as valva, basal half uniform, distal half gradually narrowed; cornutus absent.

Female genitalia ( Fig. 24 View FIGURES 21 – 24 ). Papillae anales broad, with short setae. Intersegmental membrane between papillae anales and eighth abdominal segment about three times length of papillae anales. Apophysis posterior 1.5 times length of apophysis anterior. Eighth segment straight on posterior margin, with dense long setae; eighth sternite sub-triangular in anterior 1/3; eighth tergite rectangular. Antrum sub-rectangular, width about 1.5 times of length, posteriorly concave in broad V shape. Ductus bursae narrow in posterior 2/3, broadened towards corpus bursae; about 2/3 length of corpus bursae. Corpus bursae elongate oval; two signa: one rhombic, weakly sclerotized on one side, with sclerotized ridge medially, another in broad V shape formed by combination of two triangular sclerites. Ductus seminalis arising from anterior 1/3 of ductus bursae, about three times length of corpus bursae, basal 1/3 broad, distal 2/3 narrow, helically coiled, with dense microspines.

Biology. In the Russian Far East, the species is found exclusively in the sparse seaside oakeries with prevalence of Quercus dentata Thunb. (Fagaceae) .

Distribution. China (Henan, Hubei, Shanxi, Sichuan, Zhejiang), Russia (Far East).

Diagnosis. Atkinsonia swetlanae can be distinguished from its congeners by the forewing having several streaks along veins and by the uncus considerably widened apically in the male genitalia.
