Diagnosis.
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).
