Material examined. CHINA: Shanxi Province: 3Ƌ, Mt. Mianshan, Jiexiu, 1370 m, 18.vii.2014, leg. Tengteng Liu, Meiqing Yang and Sihan Lu, genitalia slide No. LLJ15044; Hubei Province: 2♀, Taohuachong, Yingshan County, 635 m, 23.vi.2014, leg. Wei Guan and Meiqing Yang, genitalia slide No. LLJ15048.
Redescription. Adult (Fig. 8). Wingspan 11.5–13.0 mm. Head white. Labial palpus white; second segment with basal half brown on outer surface; third segment brown at basal 1/3 and 2/3. Antenna with scape white; flagellum alternately black and white. Thorax grayish white, mixed with brown or ochreous brown scales; tegula grayish white, ochreous brown at base. Forewing ground color white, suffused with brown and dark brown scales, tinged with black scales, apex black; markings black, overlaid with raised scales: costa with spot at base, at 2/5 and 2/3 respectively; discal, discocellular and plical spots overlaid with raised scales, fold with raised white scales at 2/3; tornus with an ovate spot; cilia white, tinged with black along termen, grayish at tornus. Hindwing and cilia grayish brown. Foreleg brown, tarsus black, each tarsomere white apically; midleg brown, tibia white; hindleg pale yellowish white.
Male genitalia (Fig. 18). Uncus with basal 2/3 rectangular, distal 1/3 triangular, posterior margin rounded, densely setose. Gnathos with anteromedian process small. Tegumen furcate from anterior 2/3, having a large membranous ventral process. Glandiductor symmetrical, about same length as tegumen, dilated triangularly at base, slender distally, curved. Valva subrectangular; outer lobe clubbed, setose, exceeding tip of glandiductor; inner lobe thicker, triangular, tapered to apex. Juxta about 1/2 length of outer lobe of valva, acute at apex. Vinculum inverted triangular; saccus concave at middle on anterior margin. Aedeagus about 1/2 length of tegumen-uncus complex, slender, curved, dilated basally, distal 1/4 truncate.
Female genitalia (Figs. 28, 35). Apophyses anteriores about 2/3 length of apophyses posteriores. Ostium bursae with lateral lobes small, rounded. Ductus bursae about same as length as corpus bursae, with a triangular sclerite posteriorly. Corpus bursae ovate, with sparse granules on inner surface; signum subtriangular, spines anterolateral.
Diagnosis. Parastenolechia collucata differs from its congeners in the male genitalia by the tegumen having a large membranous ventral process, and in the female genitalia by the extremely small rounded lateral lobes of the ostium bursae.
Distribution. China (Gansu, Hubei, Shaanxi, Shanxi), North Korea, Russia.
