Description. Adult ( Fig. 1 ) with wingspan 8.0−11.0 mm. Head: Grayish brown. Frons white. Antenna brownish black. Labial palpus white, second segment longest, terminal segment extended forward. Thorax: Dorsum and tegula brownish black. Forewing ground color grayish brown; costal strigulae white, nine pairs; 1st and 2nd pairs appear as a single indistinct white mark; basal fascia grayish black, between base and 1st pair of strigulae; 3rd and 4th pairs seemingly splitting into four pairs of narrow strigulae by fine black lines at middle of each pair; subbasal fascia grayish black, between 2nd and 3rd pairs; 5th pair emitting a short plumbeous line; a short black median fascia running from between middle of 4th and 5th pairs of strigulae to upper corner of cell; a black postmedian fascia running from between middle of 6th and 7th pairs of strigulae to upper 2/5 of termen; 7th pair emitting a plumbeous line that reaches upper 1/3 of termen; 9th pair largest and pronounced, splitting into two conspicuous white spots; preterminal fascia between 8th and 9th pairs; submedian patch black, sloped outward, extending upward from basal 2/5 of dorsum to 1/3 width of forewing; dorsal blotch adjacent and parallel to submedian patch, formed by two pairs of yellowish-white lines; cilia pale yellowish brown. Hindwing brown, costal margin grayish white on basal 2/3, cilia gray. Abdomen: Male genitalia ( Fig. 7 ) with tegumen long and narrow, with a pair of ear-like flaps on its lateral wall. Valva long and narrow; costa straight, with some bristles; neck of valva slightly swallowed ventrally, with bristles; cucullus narrow, almost parallel-sided, with bristles and spines, the bristles of cucullus from ventral basally to the middle of the neck of valva. Aedeagus wide in basal 3/4, abruptly narrowed in distal 1/4; cornutus absent. Female genitalia ( Fig. 12 ) with papilla analis narrow, as long as apophysis posteriores; apophyses anteriores about same length as apophyses posteriores; ostium bursae roundly surrounded by an incomplete sclerotized ring; ductus bursae short and narrow, almost entirely sclerotized; corpus bursae ovoid, with two small, horn-shaped signa. Sterigma consisting of a weakly sclerotized plate in relief on the sternite VIII, U-shape concaved posteriorly to the ostium.

Diagnosis. This species can be easily distinguished from its congeners by the narrow, elongate cucullus in the male genitalia, and the U-shaped concave sterigma in the female genitalia.

Distribution. China (Henan, Tianjin).

Etymology. The specific name comes from the Latin prefix angusti- (narrow) and cucullus, in reference to the narrow cucullus in the male genitalia.
