Remarks.
This species is easy distinguished from other species of
Angustuma
Xing & Li, 2013
by the dorsal coloration and marks. Its male genitalia are very similar to those of
Angustuma nigricarina
(
Li, 1986
)
, but the shapes of the aedeagal shaft and ventral apophysis (
Fig. 28
) in lateral view are different.
Etymology.
The specific epithet, a combination of “flavus”, meaning yellow, and “macula”, meaning spot, refers to the forewing having a large yellow spot on the lateral margin.
