Leptophion radiatus ( Uchida, 1956)

Stauropodoctonus orientalis Morley ; Dutt, 1923: 17. In part. Misidentification (cf. Gauld & Mitchell, 1981).

Spilophion radiatus Uchida, 1956: 18 . Holotype female, Taiwan (Hokkaido University Insect Collection, Japan).

Specimens examined. Male, Taiwan: Fenchifu, Chial hsien, 12–13. viii. 1983 (I. Kanazawa, light trap). Females, Taiwan: Lushan-wenchuan, Nantou hsien, 15. v. 1984 (S. Yoshimatsu, light trap); Fenchifu, Chial hsien, 12–13. viii. 1983 (I. Kanazawa, light trap).

Diagnosis. This species can be distinguished from other species of Leptophion by the following combination of character states: (1) distal pecten of tarsal claws of hind legs distinctly longer than true apex of claw and other pectens; (2) hind wing without apparently elongated penultimate hamulus on vein R 1; (3) the angle of an intersection of two veins of hind wing, R 1 and Rs, around 45°; (4) vein Rs of hind wing, straight to weakly curved; (5) proximal areas of marginal cell and second subdiscal cell of fore wing with a clouded area; and (6) AI, 0.7–1.0.

Distribution. Oriental region ( Taiwan, India, Malaysia, and Nepal) ( Yu et al., 2012).

Remarks. This species has a clouded area on proximal areas of marginal cell and second subdiscal cell of fore wing, and the angle of an intersection of two veins of hind wing, R 1 and Rs, is around 45°. In Leptophion , these character states are recognized only in this species.
