Diagnosis.
This species is similar to
A.
(
A.
)
alpha
and
A.
(
A.
)
taiwanensis
in having a short broad white dorsal band on the forewing, a white dorsal spot beyond the middle of the wing, and a dark dorsal spot before the middle of the wing (between the preceeding white band and spot).
Argyresthia
(
A.
)
beta
can be separated from the latter two species by the forewing having a triangular white dorsal spot beyond the middle of the wing, which is subtrapezoidal in the latter two species. In the male genitalia of
A.
(
A.
)
beta
the phallus is 3.8 times as long as the width of the valva (
Figs. 134
,
190
), whereas it is 7.0 times as long as the width of the valva in
A.
(
A.
)
alpha
(
Figs. 133
,
189
) and
2.8 in
A.
(
A.
)
taiwanensis
.
Argyresthia
(
A.
)
alpha
can be further separated from
A.
(
A.
)
taiwanensis
by the forewing having a quadrate golden-brown dorsal spot before the middle of the wing, which extends obliquely outward in the latter species.
