This species resembles S. sinevi Ponomarenko et Park in the male genitalia, but can be separated from it by the process of the uncus brachium located more distally and acute apically, and the saccular margin of the valva slightly concave near the base ( Fig. 3 ). In S. sinevi , the process of the uncus brachium arises near the middle and is narrowly rounded apically, and the saccular margin of the valva is almost straight ( Fig. 32 ). The wing pattern, the stout brachia of the uncus and the irregularly oval valva are very similar in S. percnaula and S. stagnigera . Besides differences in size (with wingspan 21.0–23.0 mm in S. percnaula and 17.0 mm in S. stagnigera ), there are no external differences. In the male genitalia the only tiny difference is the apex of the anellus acuminate in S. percnaula ( Fig. 3 ) but slightly rounded in S. stagnigera ( Fig. 31 ). Scaeosopha stagnigera should be a geographic variation of S. percnaula is therefore considered as a junior synonym of S. percnaula herein.
