Head blackish, tinged with brown scales; labial palpus blackish-brown, scattered yellow or brown scales; second segment plumpish, thicker than first and second segment; third segment small, elongated. Ground colour of thorax dark brown. Prothorax pale brownish, furry. Mesothorax yellowish-brown, with light grey. Metathorax brown. Patagium reddish-brown. Tegula yellowish-brown, with light grey fore part, with dark brownish dividing line. Femur and tibia of forelegs reddish-brown, furry; tarsus greyish-brown. Femur and tibia of mid-legs brown, furry, tibia with a pair of spurs in the lower part; tarsus greyish-brown, with spines. Femur of hind-legs yellowish-brown; tarsus brown, furry, with two pairs of spurs in the middle part and lower part; tibia yellowish-brown, with spines. Ground colour of forewing greenish brown; Distinct line straight, anteriorly reddish-brown, posteriorly dark brown, represented from apex to base along the subcostal vein. Six lines: basal one reddish-brown, straight; antemedial one reddish-brown, slightly leaning to apex; median one thin, wavy, sticking out to base at posterior part; postmedial one yellowish basally, weakly dark brown distally; subterminal one brown, diffused, zigzag; terminal one yellowish-brown, wavy. Cilia brown. Orbicular spot dark brown, small. Ground colour of hind-wing brown. Five lines: antemedial one straight; median one wavy; postmedial one straight; subterminal one brownish, dotted; terminal one yellowish. Cilia brown. Abdomen light brown.

Male genitalia (Fig. 4 View Figure 4 ). Uncus short, broad, bifurcated, with pointed apex, basal part broadened rectangular shape; tegumen curved, with long hairy setose; valva ear-shape, with strongly setose at sacculus, apex with one pointed spine; costa curved, slightly sclerotised, weakly setose; clasper weakly sclerotised; harpe sclerotised, curved, upturned; juxta plate-like, bifurcate in the middle part and lower part; hair pencil 2.5 times longer than valva, elastic; vinculum thin, with risen top and basal part; saccus inverted triangle shape; aedeagus slender, bent, 1.5 times longer than valva, with weakly sclerotised carina, apex pointed.

Female genitalia. Unknown.

Diagnosis

This species is similar to E. torsa in having forewing line from apex to base along the subcostal vein; line patterns from forewing to hind-wing ( Guenée 1852). However, they can be distinguished by the following characters: the head with simple antennae; dark brown ground colour of wings; the forewing with distinct straight reddish line from apex to base along the subcostal vein and orbicular smaller than E. torsa .

Distribution

Palaearctic: Korea (new record); Oriental: Nepal, Bangladesh, India, Sri Lanka ( Guenée 1852, Walker 1865, Haruta 1993).

Ecology

Hostplants Pithecellobium dulce (Roxb.) Benth. [Leguminosae (M)] ( Robinson et al. 2023).

Notes

This species is thought to be widely distributed from India to Southeast Asia, but is poorly documented ( Holloway 2005). The discovery in South Korea represents the species’ northernmost known occurrence, applying that it is expanding northwards. The specimen used in the present study has a 48 mm wing-span. However, earlier, Guenée (1852) measured 55 mm wing-span in this species.
