Redescription. Adult (Figs. 23–26). Wingspan 11–15 mm. Head light grey; labial palpi mainly light grey, curved upwards, twice as long as the head; basal segment light grey, half as long as second. Second segment with trapezoid patch of hair-like scales, on outer side with two dark brown transverse streaks at the base and before apex, on inner side with one dark brown transverse streak before apex; dorsal edge of segment light grey basally and whitish distally. Third segment of labial palpus longer than second, with dark brown ring at middle and brown apex (Fig. 8). Antennae with scape and basal 1/4 of flagellum dark brown dorsally and light grey ventrally; distal 3/ 4 of flagellum with alternate light grey and dark grey rings. Thorax concolorous with the head. Forelegs and middle legs mainly dark grey on outer side with light grey ring at the apices of femur, tibia and each tarsomere; both pairs of legs whitish on the inner side; spurs dark grey. Hindlegs light grey with scattered dark scales on femur and tibia; each tarsomere dark grey with white apical ring; spurs dark grey. Forewings narrow, lanceolate, with tapered falcate apex. Ground colour grey with scattered dark grey scales; pattern formed by longitudinal dark brown, orange and white streaks and lines, including a narrow, dark brown band along median line about 1/3 wing length and a white, wedge-shaped narrow line on distal half of wing, plus three, parallel, short white streaks abutting termen. Fringe light grey with dark brown middle band and concolorous edge. Hindwings unicolourous, grey brown, fringe concolourous with light grey middle.
Male genitalia (Figs. 28–29, 33–35). Uncus slightly narrowed distally, with a row of long setae along posterior edge except for middle part with V-shaped incision. Tegumen deeply hollowed on sides at 3/4 distally, with strong transverse posterior sclerotization and with deep triangular cut between widened anterolateral parts. Gnathos hook-like, curved at about 1/3 basally. Cucullus slender with clavate distal part. Valvella digitate, about half as long as cucullus. Sacculus and juxta ankylosed into semisclerotised setaceous tube joining with vinculum and surrounding aedeagus. Saccus wide and flat-topped. Aedeagus with basal half 4 times thicker than distal half, with toothed ventral plate just beyond the middle.
Female genitalia (Figs. 30–32). Papilla analis ovoid, with rounded sclerotization at base; ovipositor telescopic, intersegmental membrane between IX and VIII about 2/3 length of apophyses posteriores. Segment VIII membranous ventrally. Ostium on level of anterior margin of segment VIII. Antrum cup-shaped, wider than 1/ 2 width of segment VIII, narrowed before ring-like cingulum. Ductus bursae narrow, membranous, longer than corpus bursae, ductus seminalis junction at 2/3 distally. Corpus bursae ovoid, about 3/5 as long as ductus bursae; signum large, about 1/3 of bursae copulatrix width, in posterior half of corpus bursae.
Diagnosis. Sophronia orientalis is similar to S. illustrella in forewing pattern and genitalia of both sexes. In the male genitalia it can be distinguished by the relatively longer aedeagus, which is slightly longer that the total length of the uncus plus the tegumen, with a narrow distal half and a tube-like apex; in the female genitalia the cup-shaped antrum is diagnostic. In S. illustrella the aedeagus is shorter than the uncus plus the tegumen, wider in the distal part and with a different shaped apex, whilst the female antrum is goblet-shaped.
Distribution. Russia (Far East: Primorsky krai), Japan (Hokkaido, Honshu), China (Gansu, Shaanxi) (Li & Zheng 1998; Omelko 1999; Li 2002; Park & Ponomarenko 2007; Ponomarenko 2008, 2016; Sakamaki & Ueda 2013).
Remarks. Sophronia orientalis was described from seven specimens collected in Shaanxi and Qinghai Provinces, China (Li & Zheng 1998: 309). Sophronia iciculata was described from 11 males and 19 females collected in Primorsky krai of the Russian Far East (Omelko 1999: 169). The comparison of adults and the male genitalia of specimens collected in type locality of S. iciculata with photographs of the holotype of S. orientalis allows us to establish S. iciculata Omelko, 1999 as a junior synonym of S. orientalis Li & Zheng, 1998. The pattern of the forewing and the male genitalia in ventral aspect of both species are almost identical. Small diferences in the male genitalia are seen in the length of the valvella, which is slightly longer in specimens from Far Eastern population, and in the size of the saccus, which is wider in Chinese population; these represent intraspecific variability. Genitalia of Japanese specimens were not studied.
