Key to the Taiwanese species of Leptophion

1. Hind wing with non-uniform shaped hamuli on R1, penultimate hamulus significantly elongated ( Fig. 13 ). Proximal part of marginal cell of fore wing with an infumate area ( Fig. 32 ). Postero-proximal part of second subdiscal cell of fore wing entirely hyaline without an infumate area ( Fig. 32 ). Proximal corner of marginal cell of hind wing about 95° ( Fig. 32 ). Lateral carinae of scutellum developed on anterior 0.8–0.9 ( Fig. 11 )................................ L. maculipennis ( Cameron, 1905)

- Hind wing with uniform hamuli on R1, penultimate hamulus not elongated ( Figs 21 , 30 ). Proximal part of marginal cell of fore wing with an infumate area ( Figs 33, 34 ). Postero-proximal part of second subdiscal cell of fore wing with an infumate area ( Figs 33, 34 ). Proximal corner of marginal cell of hind wing about 45° ( Figs 33, 34 ). Lateral carinae of scutellum developed on anterior 0.2 ( Figs 19 , 28 )................................................................................ 2

2. 1m-cu of fore wing strongly sinuous ( Fig. 33 ). Postero-distal corner of second discal cell of fore wing forming an obtuse angle, about 105–110° ( Fig. 33 ). Fore wing with AI=1.1–1.4; ICI=0.9–1.0; SDI=1.1–1.2 ( Fig. 33 ). Fore wing weakly infumate except for proximal part of marginal cell often with a more or less distinct infumate area (but occasionally no more infumate than apex of cell), and postero-proximal part of second subdiscal cell with a distinct infumate area ( Fig. 33 ). Fore wing 17.0–21.0 mm............................................................... L. giganteus Shimizu & Watanabe , sp. nov.

- 1m-cu of fore wing abruptly curved ( Fig. 34 ). Postero-distal corner of second discal cell of fore wing forming an acute angle, about 85° ( Fig. 34 ). Fore wing with AI=0.8–0.9; ICI=0.5–0.7; SDI=0.9–1.0 ( Fig. 34 ). Fore wing hyaline except for proximal part of marginal cell and postero-proximal corner of second subdiscal cell each with an infumate area ( Fig. 34 ). Fore wing 13.0–15.0 mm.................................................................... L. radiatus ( Uchida, 1956)
