21. Argyresthia (Argyresthia) papillata , sp. nov. ( Figs. 31 View FIGURES 28 – 35 , 100 View FIGURES 96 – 101 , 156 View FIGURES 154 – 157 , 212 View FIGURES 209 – 220 )

Description. Adult ( Fig. 31 View FIGURES 28 – 35 ) wingspan 11.5 mm. Head white. Labial palpus white dorsally, pale yellow ventrally. Antenna with scape white, pecten brownish fuscous; flagellum white, ringed with blackish gray. Foreleg with femur gray on inner surface, tibia and first tarsomere of tarsus blackish fuscous on inner surface, other tarsomeres black distally, remainder white; midleg mostly pale yellowish white, tarsus gray on distal part of each tarsomere; hindleg mostly grayish white, tibia and first tarsomere blackish gray on outer surface, other tarsomeres blackish gray on outer surface distally. Thorax white, tinged with pale yellow; tegula golden fuscous to dark fuscous. Forewing ratio 4.3; grayish fuscous; costa with several transverse black striae on basal 3/5, with a white spot at distal 1/10; blackish-gray streak below basal half of fold; dorsal band pale yellowish white, from base to middle of dorsum, elongate rectangular, straight apically; dorsal spot black, situated beyond end of dorsal band, extending to fold anteriorly; black dot at tornus and a white spot above it; termen with a few black dots; cilia white adjacent to costal spots, black around apex, dark gray near tornus. Hindwing and cilia uniformly gray.

Male genitalia ( Figs. 100 View FIGURES 96 – 101 , 156 View FIGURES 154 – 157 , 212 View FIGURES 209 – 220 ): Tuba analis slightly shorter than width of valva. Socius covered with 9̄10 scale-like setae, with a small posterior papilla that bears one to two setae ( Fig. 212 View FIGURES 209 – 220 ). Gnathos inflated distally, with 7̄13 long thick setae apically. Valva with basal 2/5 uniform in width, distal 3/5 narrowed, rounded apically; with a row of long thick setae from base near ventral margin to distal area. Saccus shorter than width of valva, distal half linear. Phallus straight, 4.2 times as long as width of valva ( Fig. 156 View FIGURES 154 – 157 ). Second sternite with 8̄11 microsetae in each row; eighth sternite V-shaped. Coremata present.

Female unknown.

Distribution. China (Hebei, Inner Mongolia, Shanxi).

Diagnosis. This species resembles A. (A.) trigonophylla , sp. nov., superficially. It can be separated by the forewing with the white dorsal band extending from the base to the middle of the dorsum; the socius with a small papilla posteriorly; and the phallus 4.2 times the length of the valva in the male genitalia. In A. (A.) trigonophylla , sp. nov., the dorsal band on the forewing extends to above tornus; the socius is triangularly protruded posteriorly; and the phallus is 5.6̄6.4 times the length of the valva in the male genitalia.

Etymology. The specific name is derived from the Latin papillatus, meaning papillary, referring to the small papilla of the socius.
