( Figs. 7 , 13, 14 , 19 , 23 ) DIAGNOSIS Eudarcia longiphalla sp. nov. is externally similar to E . gwangneungensis sp. nov. , but it can be distinguished by termen margin of forewing without light yellow hairs. The male genitalia are similar to E. prolongata Xiao & Li, 2009 , but differ from male genitalia in the shorter elongated uncus, and fairly wide uncus and tegumen part. Furthermore, the male genitalia differ from E. dentate Gaedike, 2000 and E. prolongata . The gnathos is very short and fused with middle of uncus and tegumen part; phallus is relatively slender and long. In addition, this species can be identified readily based on female genitalia; antrum well developed; ductus bursae without spines and very long, relatively small, and very sclerotized. Figs. 21-24.

Hindwing slightly narrow: L/W ratio 4.16;costa straight;Sc + R straight to 4/5 of the costa;Rs terminating at the apex; base of M weakly developed; M 1 and M 2 fused, M 1 + 2 and M 3 forked; CuP absent; CuA 1 and CuA 2 forked,1A + 2A weak;3A present but considerably weak. Legs: epiphysis present; covered with light brown hairs. Abdomen: covered with brown scales; corethrogyne absent. Male genitalia ( Figs. 13, 14 ). Tegumen, vinculum, and uncus fused with slightly wide triangular shape; uncus very short, elongated, hooked; vinculum V-shaped; saccus elongated downward, slightly thick, 0.86 times as long as the height of the ring; valva wide; ampulla (apex of valva) rounded and apical part hooked; harp relatively short and blunt (lateral view); transtilla slender, slightly short and well developed; phallus long and slender, cylindrical, longer than 2.66 times the height of the ring, cornuti present with 2 spines. Female genitalia ( Fig. 19 ). Ovipositor very long and narrow; papillae anales narrow, some short satae at apex; ostium bursae located at anterior margin of sternum VIII, slightly narrowed bell-shaped; apophyses posteriores very thin, 2.7 times longer than apophyses anteriores; basal part of apophyses anteriores thick and slightly short; antrum wide and well developed; ductus bursae narrow and very long; corpus bursae narrow and well sclerotized.
