Diagnosis. This species can be distinguished from its congeners in the male genitalia by the distally bifurcated socius and the subquadrate valva.
Description. Adult (Fig. 3 b): Wingspan 7.0‒11.0 mm. Head snowy white. Antenna with scape white, pecten brown; flagellum white except basal four flagellomeres deep brown on dorsal surface. Labial palpus white, first and second palpomeres mixed with greyish brown scales deepening to darkish brown on outer surface. Thorax white, with a brown transverse-band on posterior 1/4. Tegula white, with a large dark brown spot at base. Forewing with M3 and CuA1 separated; white; costal margin with basal 1/3 black, distal half yellowish brown, diffused ventrad across M2, darkened along distal 1/4 and somewhat forming a narrow band, from beyond 1/2 to 3/4 with three white strigulae extending obliquely and parallel outward to about anterior 1/5, alternated three yellowish brown wider strigulae which are edged with black scales along its inner margin anteriorly; dorsal fascia wide, shining dark brown, margined with black scales, narrowed gradually to beneath first yellowish brown strigula from costa; cilia white, greyish brown along costal margin, with a brown line near middle along termen. Hindwing with M3 and CuA1 connate from lower angle of cell; greyish brown, deeper in distal half; cilia white, pale brown along costal margin and in basal part of distal half on dorsum. Foreleg deep greyish brown except coxa white; mid- and hindlegs white, midleg with tibia covered with blackish brown scales distally, tarsi of mid- and hindlegs blackish brown at apex of each segment on outer side. Abdomen yellowish white on ventral surface, greyish white on dorsal surface.
Male genitalia (Fig. 4 b): Socius elongate, longer than valva, slightly widened from base to apex, with sparse setae in distal half, bifurcated distally: dorsal branch stout, subtriangular, slightly hooked apically, with a short spine at base; ventral branch slender, about three times length of dorsal one, with two apical denticles. Tuba analis membranous, with ventral sclerotized band extending from base to middle. Gnathos transversely banded, concave medially on posterior margin, forming triangular process posterolaterally. Valva subquadrate, ventral margin arched slightly, with a small proximal process, with numerous denticles scattered along apex and along distal part of ventral margin, apex truncate. Saccus short, nearly squared. Aedeagus twice length of valva, with numerous tiny protuberances in distal 1/5 except before apex; cornutus absent.
Female genitalia (Fig. 5 a): Apophyses anteriores as long as apophyses posteriores. Lamella postvaginalis subelliptic, covered with dense setae, about 1/3 width of eighth tergum. Seventh sternite concave in heart shape at middle on posterior margin, with large sclerotized fan-shaped plate placed on lateral side of concavity, heavily sclerotized along inner margin. Antrum indistinct; ductus bursae approximately three times length of corpus bursae. Corpus bursae ovate.
Distribution. China (Guangdong, Guangxi, Tianjin, Zhejiang).
Etymology. The specific name is derived from the Latin adjective truncatus, meaning truncate, referring to the truncate apex of the valva in the male genitalia.
