( Figs. 13 , 34 , 53, 53 a–c)

Anarsia choana Park, 1995: 61 ; Ponomarenko, 2009: 345. TL: Taiwan (Taipei). The holotype in USNM.

Diagnosis. Adult ( Figs. 13 , 34 ): Wingspan, 11.5 mm. The species is superficially similar to A. patulella (Walker) , but can be distinguished from the latter by the forewing: the blackish streak below costal patch in cell poorly developed, the long hair pencil on the underside of forewing absent, and the second segment of labial palpus in male ( Fig. 34 ) greatly elongated anteriorly with long scale tufts. It can also be easily distinguished by the male genitalia with the hook-shaped basal process near the base of the left valva and the short-stalked, palmate-modified scales.

Male genitalia ( Figs. 53, 53 a–c): Uncus short, broadened basally, pointed apically; socius ovate. Tegumen longer than valva, slightly narrowed medially. Left valva semiovate, with a long, narrow, strongly curved process basally and a patch of palmately modified scales distally. Right valva slightly elongate, with membranous semiovate lobes on costa medially; patch of modified scales similar to that of left valva. Phallus slender, curved, as long as valva.
