Remarks.

This species can be distinguished from the other species of this genus by the pair of fingerlike aedeagal processes, the short preatrium and the expanded apex of aedeagal shaft in lateral view (Figs 9, 10).

Etymology.

The specific name is derived from the Latin words “nigra” (black) and “linea” (line), referring to the brown longitudinal marking on the fore wing (Fig. 1).
