13. Anarsia choana Park, 1995

(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.
