description: 3. Argyresthia (Blastotere) cineretra, sp. nov. (Figs. 2, 14, 15, 86, 143, 199, 255)
Description. Adult (Figs. 14, 15) wingspan 8.5̄10.0 mm. Head white, face tinged with yellowish white. Labial palpus pale yellowish fuscous, mixed with gray laterally. Antenna with scape white, pecten yellowish fuscous; flagellum grayish white, ringed with black. Foreleg with femur densely covered with dark gray transverse striae on inner surface, gray laterally, tibia blackish gray on inner surface, dotted with blackish gray at middle on outer surface, tarsus blackish gray on inner surface and on dorsoapical part of each tarsomere, remainder grayish white; midleg grayish white, tibia dotted with blackish gray dorsally near base and at middle, tarsus black distally on each tarsomere; hindleg gray, tarsus black on distal part of each tarsomere. Thorax white; tegula golden. Forewing ratio 4.0; ground color gray, tinged with golden fuscous below base of costa and fold; costa with a black spot near apex, with white dot before and beyond it; termen grayish white, with several black dots; black spot at costa before middle, at middle of cell, and below basal 2/5 of fold, arranged in an oblique inward directed line, anterior two spots sometimes joined; black spot at end of fold extending to tornus; dorsal fascia black, from before middle of wing extending obliquely outward to costal 2/3, darkened at costa; black streak from lower angle of cell oblique to costal 5/6, parallel to preceding fascia; cilia blackish gray basally and distally, white medially on costa and around apex, white at place of white costal dots, grayish white near tornus. Hindwing gray; cilia grayish white. Abdomen dark silvery gray dorsally, pale silvery gray ventrally.
Female (Fig. 15) similar to male in size and wing pattern, but forewing with dense golden scales below costa diffused a longer distance outward, sometimes reaching spot at middle of cell, making the latter paler, indistinct, or absent; golden streak below fold extending to middle of fold; black fascia from costal 2/3 to before middle of dorsum; black streak from lower angle of cell to costal 5/6, golden fuscous near costa.
Venation (Fig. 2): Forewing with R4 and R5 stalked; hindwing with M3 and CuA1 stalked.
Male genitalia (Figs. 86, 143, 199): Tuba analis shorter than width of valva. Socius covered with 11̄17 scalelike setae, bearing a single seta posteriorly (Fig. 199). Valva widest at basal 2/5, dorsal margin slightly concave at basal 2/5, ventral margin arched in basal half; distal half narrowed to bluntly rounded apex; transtilla broad and short, triangular. Saccus triangular, truncate apically. Phallus curved to almost straight, about 3.5 times as long as width of valva; cornutus about 2/5 length of phallus, with about ten strong denticles, shortened towards base (Figs. 143, 143 a). Second sternite with about ten micro-setae in each row; eighth sternite Y-shaped. Coremata present.
Female genitalia (Fig. 255): Ovipositor 2.5 times as long as eighth segment. Anterior apophysis 2/3 length of posterior apophysis, bifurcate from before distal 1/3; branch bifurcate a second time, its dorsal branch extending to lamella postvaginalis, ventral branch fused and forming ventral margin of ostium bursae. Lamella postvaginalis hourglass-shaped. Antrum funnel-shaped, about 5/6 length of eighth segment. Ductus bursae spinulate before opening of ductus seminalis; ductus seminalis originating from about posterior 2/5 of ductus bursae. Corpus bursae oval, with dense denticles; signum anvil-shaped, with lateral horns extending outward.
