Liu, Tengteng, Wang, Shuxia & Li, Houhun, 2017, Review of the genus Argyresthia Hübner, [1825] (Lepidoptera: Yponomeutoidea: Argyresthiidae) from China, with descriptions of forty-three new species, Zootaxa 4292 (1), pp. 1-135 : 18-19

4. Argyresthia (Blastotere) affinicineretra , sp. nov. ( Figs. 16 , 87 , 144 , 200 )

Description. Adult ( Fig. 16 ) wingspan 8.5 mm. Head white, face tinged with golden. Labial palpus yellow, mixed with gray laterally. Antenna with scape white, tinged with pale fuscous, pecten yellowish fuscous; flagellum white, ringed with grayish black. Foreleg with femur densely covered with gray transverse striae on inner surface, gray laterally, tibia and tarsus blackish fuscous; midleg yellowish white mixed with gray, tibia dotted with blackish gray dorsally near base and at middle, tarsus grayish fuscous distally on each tarsomere; hindleg grayish white except tarsus black at apex of each tarsomere. Thorax white; tegula golden fuscous. Forewing ratio 4.5; ground color pale grayish white, dotted with blackish gray; costa with three black spots, largest one before middle, one at distal 1/6, one near apex, a white dot before and beyond the last; golden fuscous stripes below basal 1/5 of costa and fold, each approximately 1/3 width of wing, stripe below fold well defined, rectangular; large black spot at middle of cell; dorsal fascia black, from before middle of wing obliquely outward to beyond costal 2/3; large black spot at tornus; cilia blackish gray along costa and apex, white at place of white costal dots, gray near tornus. Hindwing gray; cilia grayish white. Abdomen dark silvery gray dorsally, pale silvery gray ventrally.

Venation: Forewing with R4 and R5 stalked; hindwing with M3 and CuA1 from same point.

Male genitalia ( Figs. 87 , 144 , 200 ): Tuba analis with length equal to width of valva. Socius covered with 15̄18 scale-like setae, bearing a single seta posteriorly ( Fig. 200 ). Valva with basal half nearly uniform in width, distal half narrowed to rounded apex; transtilla broad, parallel-sided. Saccus with basal 2/3 wider, distal 1/3 apparently narrowed, clavate. Phallus straight, about 4.1 times as long as width of valva; cornutus about 1/3 length of phallus, with approximately seven strong denticles, distal four equal in size, others shortened towards base ( Figs. 144, 144 a). Second sternite with about ten micro-setae in each row; eighth sternite Y-shaped. Coremata present.

Female unknown.

Type material. CHINA: Holotype, Ƌ, Mt. Jizu (25.96°N, 100.39°E), Dali City , Yunnan Province, 2228 m, 27.vii.2014, leg. Kaijian Teng, Wei Guan, Xiuchun Wang and Shurong Liu, slide no. LTT12710.

Distribution. China (Yunnan).

Diagnosis. This new species resembles A. (B.) cineretra superficially. It can be separated by the forewing having a well-defined rectangular stripe below the fold, the valva with the basal half nearly uniform in width, and the cornutus with about seven strong denticles in the male genitalia. In A. (B.) cineretra the forewing pattern below the base of the fold is poorly defined, the valva is widest in the basal 2/5, and the cornutus has about 10 strong denticles.

Etymology. The specific name is derived from the Latin prefix affin -, meaning similar, and the specific name of its congener A. (B.) cineretra , indicating the similarity of the two species.
