Ceratostigma gracilis Li, 2002

( Figs 1–15 View FIGURES 1–7 View FIGURES 8–15 )

Ceratostigma gracilis Li, 2002: 1595 . Type locality: China (Guangxi, Longsheng, Tianpingshan ).

Diagnosis. Male. Forewing ( Fig. 1 View FIGURES 1–7 ) basal one-fifth with a slightly curved greyish white stripe; radial fork with branches diverging at an angle about 90°. Epiproct ( Figs 3–4 View FIGURES 1–7 ) nearly triangular, pointed at apex, with a nearly Ushaped sclerotized area at base; hypandrium ( Figs 5–6 View FIGURES 1–7 ) with a broad ridge at middle. Female. Forewing ( Fig. 8 View FIGURES 8–15 ) with a grayish white striped marking at one-fifth base; radial fork with branches diverging at an angle about 90°. Pigmented area of subgenital plate ( Figs 14–15 View FIGURES 8–15 ) roughly T-shaped, distally flat; dorsal valve ( Figs 12–13 View FIGURES 8–15 ) anterior one-third with a slightly sclerotized area.

Distribution. China (Guangxi).

Material examined. Holotype male, CHINA: Guangxi, Longsheng, Tianpingshan [25°39’N, 109°55’E], 680 m, 12.VII.1982, Fasheng Li ( CAU) GoogleMaps ; Paratype: 1 female, same as holotype; 1 male, 1 female, CHINA: Guangxi, Jiuxiu, Dayao Mountain [23°58’N, 110°07’E], 720 m, 23. VI GoogleMaps .1982, Fasheng Li ( CAU) .

Remarks. Ceratostigma gracilis is similar to C. macrostigmatum in male forewing basal one-fifth with a slightly curved greyish white stripe; radial fork with branches diverging at an angle less than 90°; epiproct nearly triangular, pointed at apex, with a nearly U-shaped sclerotized area at base; hypandrium with a broad ridge in the medium. C. gracilis can be distinguished from C. macrostigmatum by the hypandrium rounded apically, while the hypandrium of C. macrostigmatum is narrowed distally.
