description: 30. Argyresthia (Argyresthia) longa, sp. nov. (Figs. 38, 107, 163, 219, 268)
Description. Adult (Fig. 38) wingspan 13.0̄14.0 mm. Head yellowish white. Labial palpus yellowish white, mixed with fuscous laterally. Antenna with scape pale yellowish white, pecten brownish yellow; flagellum white, ringed with blackish gray. Foreleg with femur, tibia, and tarsus blackish gray on inner surface, tibia dotted with blackish gray near base, at middle, and on distal part dorsally, tarsus black on distal part of each tarsomere dorsally, remainder yellowish white; midleg mostly yellowish white, femur dotted with black ventrally at middle, tibia dotted with gray near base, at middle, and on distal part dorsally, tarsus gray on distal part of each tarsomere; hindleg white on inner surface, gray on outer surface. Thorax grayish white; tegula brownish fuscous. Forewing ratio 4.5; grayish fuscous; costa interspersed with grayish-fuscous and yellowish-white dots on basal 7/10, with yellowish-white dots more apparent on basal 3/10, with a yellowish-white dot at distal 1/5; a few white scales along veins R5 and M; grayish-fuscous streak below basal 2/5 of fold, sometimes extending to dorsum distally; dorsal band yellowish white, dotted sparsely with fuscous scales, extending to end of fold; dorsal fascia black, from before middle of wing, reaching before distal 2/5 of costa, or barely intersecting costa; cilia yellowish white adjacent to yellowish-white costal dots, blackish fuscous around apex, dark gray on termen and near tornus. Hindwing and cilia uniformly gray.
Male genitalia (Figs. 107, 163, 219): Tuba analis shorter than width of valva. Socius covered with 18̄19 scale-like setae, bearing two setae posteriorly (Fig. 219). Gnathos slightly inflated distally, with eight long thick setae apically. Valva oval, widest at basal 2/7, narrowed from 2/7 to bluntly rounded apex; with a row of thick setae from disc near ventral margin to distal area. Saccus shorter than width of valva, more or less triangular. Phallus straight, 4.1 times as long as width of valva (Fig. 163). Second sternite with about 10 micro-setae in each row; eighth sternite V-shaped. Coremata present.
Female genitalia (Fig. 268): Ovipositor equal to ductus bursae + corpus bursae in length, 2.7 times as long as eighth segment. Anterior apophysis nearly equal to posterior apophysis in length, with a short slender branch at middle disconnected with opposite branch, thus ostium bursae membranous wholly. Lamella postvaginalis narrowly triangular on anterior half, with anterior margin deeply concave, linear on posterior half. Antrum funnelshaped, 1/3 length of eighth segment. Ductus bursae sparsely spinulate before and near opening of ductus seminalis; ductus seminalis originating from middle of ductus bursae. Corpus bursae nearly round, covered with dense micro-denticles; signum with basal plate short, horns extending outward, slightly curved inward, overall somewhat water caltrop-shaped.
