Adult ( Fig. 2 ): Wingspan 15.0–17.0 mm. Filatima asiatica is superficially similar to F. pagicola ( Meyrick, 1936 ) . It can be distinguished by the forewing without a cream white spot at the costal margin, and in the male genitalia by the absence of the anellus lobes and the phallus with three cornuti ( Fig. 22 ); in F. pagicola , the forewing has an indistinct cream white spot near basal 3/4 of the costal margin ( Fig. 6 ), the anellus lobes are well developed, and the phallus has two cornuti ( Fig. 26 ). This species is similar to F. karsholti Ivinskis & Piskunov, 1989 in male genitalia, and it can be distinguished by the saccus distinctly narrowed to narrowly rounded apex, and the phallus with weakly sclerotized, folded bands in distal 2/3; in F. karsholti , the saccus is subparallel to before obtuse apex, and the phallus has a triangular sclerite in the distal 2/3 ( Fig. 23 ). Variation. The number of the teeth in the middle of the cornutus varies: two teeth are found in specimens collected from Ningxia and Qinghai ( Fig. 22-c ), while one tooth is present in specimens collected from Hebei ( Fig. 22-b ). There are some variations in the shape of the saccus: the distinctly narrowed saccus is longer than the sacculus in the specimens from China , whereas the slightly narrowed saccus is shorter than the sacculus in the specimens from Russia ( Bidzilya & Nupponen 2018 : fig. 37). Distribution. China ( Hebei , Ningxia , Qinghai ), Kyrgyzstan , Mongolia , Russia . Note. This species is newly recorded in China .
