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 : 49

37. Argyresthia (Argyresthia) trochaula Meyrick, 1938

( Figs. 46 , 115 , 171 , 227 )

Argyresthia trochaula Meyrick, 1938 , In: Caradja & Meyrick : 22; Clarke , 1965: 288. TL: China (Yunnan). TD: BMNH (Lectotype, female).

Description. Adult ( Fig. 46 ) wingspan 16. 0 mm.

Male genitalia ( Figs. 115 , 171 , 227 ): Tuba analis shorter than width of valva. Socius covered with 26̄30 scale-like setae, bearing two long setae posteriorly ( Fig. 227 ). Gnathos not inflated distally, without long thick setae apically. Valva widest in basal 2/5, dorsal margin nearly straight, slightly arched at middle, ventral margin distinctly rounded before middle; a clump of thick setae at center, some brush-like distally. Saccus shorter than width of valva, with distal half narrowed, nearly uniform in width, rounded apically. Phallus straight, 4.0 times as long as width of valva ( Fig. 171 ). Second sternite with about 20 micro-setae in each row; eighth sternite V-shaped. Coremata present.

Material examined. Xizang Autonomous Region: 2Ƌ, Lage (29.47°N, 95.01°E), Motuo County, 3300 m, 8.viii.2003, leg. Xinpu Wang and Huaijun Xue, slide no. LTT12335.

Distribution. China (Xizang).

Diagnosis. The diagnosis is given under A. (A.) chlorella , sp. nov.

Remarks. The male genitalia of this species are described here for the first time. Although no female specimens are available, the superficial characters of this species match the original description in Meyrick (1938) and the figure in Clarke (1965). Moreover, the longitudinal central streak in the mesothorax is unique so far in the genus Argyresthia .
